Coronavirus in dogs: description, symptoms, treatment. Coronavirus infection in dogs - Radan Veterinary Clinic

A serious infectious disease - coronovirus infection in dogs develops after the penetration of the dangerous pathogen Canine Coronavirus into the body. IN initial stage pathologies with a latent form specific symptoms absent, the pet can infect other pets. IN advanced cases, with a hyperacute form, against the background of exhaustion and dehydration, the death of a sick individual is possible.

It is helpful to know how to recognize the coronavirus (FCS) in dogs. Types and forms of the disease, clinical picture in the development crown viral enteritis, effective methods of treatment and prevention are described in the article.

Causes of the disease and ways of infection

In nature, there are several varieties of coronavirus. The pathogen can be found almost everywhere. Infection of dogs occurs when Canine Coronavirus enters the body.

Pathogen dangerous infection common among animals, but not all four-legged pets get sick. Active reproduction pathogenic microflora occurs against the background of weak immunity, under poor conditions of keeping the animal, chronic infections negatively affecting the defenses.

Coronavirus enteritis in dogs was first diagnosed in Germany in the early 1970s. Later, the pathogen was identified in other regions of the world.

Ways of infection

FAC transmitted:

  • when an infected animal communicates with other dogs, cats. Animal coronavirus is also transmitted to pigs;
  • fecal-oral route;
  • less often - fecal-drop way of infection;
  • with contaminated water.

To the action of the pathogen corona viral infection sensitive four-legged pets of all breeds and categories, but greatest danger the pathogen is for puppies who are under 5 months old. Weak immunity, imperfection digestive system- factors that increase the risk of developing a dangerous infection.

General rules

Therapy scheme:

  • the use of immunostimulants;
  • appointment of vitamin complexes;
  • antiviral drugs;
  • the introduction of therapeutic and supportive solutions (droppers) to replenish the level of fluid and electrolytes;
  • symptomatic drugs: enterosorbents, to prevent internal bleeding;
  • antibiotics if secondary bacterial infection;
  • antihistamines for dogs with the development of allergies;
  • analgesics and pain medications;
  • medical diet;
  • disinfection of objects, utensils on which the pathogen may remain, boiling water.

Most drugs are not used orally, but are administered intravenously and subcutaneously. Frequent bowel movements and vomiting interfere with the full absorption of drug components oral administration: It is important to consider this point.

Coronavirus dies after exposure to certain substances and procedures:

  • chloroform, ether;
  • a strong solution of soda with a concentration of 10% (the pathogen loses its viability after 10 minutes);
  • exposure to a temperature of +56 C kills the pathogen in ten minutes.

Coronavirus in dogs cannot exist for a long time without a host: the pathogen persists in the feces for no more than two days.

Antibiotics

The optimal drug is selected by the veterinarian. Previously, a mucous mass or smear is taken to identify the pathogen. The result of the antibiotic sensitivity test gives the answer: which agent is more effective in combating the identified bacteria.

Immunotherapy

For effective therapy new generation immunomodulators are used:

  • Vitan.
  • Likopid.
  • Ribotan.
  • Galavit.

Immunomodulators not only stimulate nonspecific immunity in dogs, but also prevent severe form intoxication.

Fighting dehydration

An important element of treatment for reducing the risk of heart failure and lethal outcome. Preparations for stabilization water-salt balance injected subcutaneously and in the form of droppers.

Ready solutions:

  • Acesol.
  • Fizrastovr.
  • Quartsol.
  • Trisol and others.

Health food

The first two days after the cessation of vomiting in dogs is prescribed starvation diet. It is important that the weakened gastrointestinal tract started to recover.

On the third day, small portions of dry and wet food series "Veterinary Diet". Many well-known companies offer medicinal feed for dogs with sensitive digestion. Brands Akana, Orijen, Eukanuba, Royal Canin, Brit have lines for feeding weakened pets.

External funds

With the development of coronavirus infection, ointments and medicated creams used for application to the anus strong irritation and inflammation of delicate tissues. With frequent bowel movements, acute diarrhea stool with mucus and blood irritate the skin anus often develops redness and inflammation. Must be washed prior to application boiled water problem area, lubricate with an external agent.

At chronic diarrhea many formulations are ineffective if the animal relieves itself very often. It is not worth completely abandoning the use of ointments: the treatment of inflamed tissues reduces itching and irritation for a certain period.

Prevention

Vaccination is an effective method of preventing severe intestinal infection in dogs.

Domestic and foreign vaccines are used for immunization:

  • Vanguard Plus 5 L4 CV,
  • Multican 4, 6 or 7,
  • biocan,
  • Nobivac.

The prognosis for detecting coronavirus infection in dogs largely depends on the form and stage at which treatment is started. With a hyperacute variety of FAC, the prognosis is unfavorable, acute form may result in recovery or death of the animal. At hidden current Coronavirus enteritis recovery occurs in about ten days. The main thing is to start complex treatment on time. Veterinarians advise dogs to be vaccinated on time to avoid the severe consequences of FAC, up to and including death.

coronavirus infection dogs- This is a disease caused by an RNA-containing virus (Canine coronavirus), which has peculiar protrusions in the form of crown teeth on its shell, which was the reason for its name. The coronavirus is ubiquitous.

Puppies aged 1-3 months are most susceptible to the disease, but adult dogs, especially those participating in competitions, exhibitions and other events associated with the accumulation of animals, are also at risk. The route of infection is alimentary, most often infection occurs by eating feces.

When infected, the coronavirus enters the body of an animal and penetrates into the cylindrical epithelium within a day. thin department intestines ( lower section). It destroys epithelial cells, which are gradually rejected and this leads to atrophy of the intestinal villi.

Another unpleasant feature of the canine coronavirus is its prolonged release even after the recovery of the animal. That is, a cured dog continues to be a potential threat to unvaccinated dogs against coronavirus. for a long time.

Coronavirus infection is usually associated with a mild or subclinical form of the disease. The most characteristic symptoms of canine coronavirus are vomiting and diarrhea, which usually appear within 5-7 days after infection. With diarrhea, feces are usually watery. Apathy and weight loss may also occur. Bloody diarrhea, fever, and leukopenia are uncommon in uncomplicated caronavirus infection; such signs are indicative of other concomitant infections. Spontaneous recovery occurs in 7-10 days, although sometimes diarrhea can last several days. Deaths are very rare, most of them related to neonatal infections. The prognosis for complete recovery is favorable.

Definitive diagnosis can be made by detection of viral particles by electron microscopy or by virus isolation. PCR method. At the same time, fresh feces are examined (no later than 48 hours), since viral particles are very unstable and are destroyed when long-term storage and therefore false negative results are common.
specific treatment coronavirus infection does not exist. Carry out symptomatic therapy:

  • intravenous infusions with a significant loss of water;
  • systemic antibacterial drugs with secondary bacterial infections or the perceived danger of their development, as evidenced by fever, leukopenia, the appearance of blood in the feces;
  • immunostimulants with confirmed carriage of the virus.

For the prevention of coronavirus infection great importance has compliance with the rules of personal hygiene and maintaining cleanliness in the premises where the dog is kept, preventing the dog from eating feces during a walk. But certainly the most effective method prevention is dog vaccination against coronavirus infection. This applies to dogs of any age, gender, breed, and first of all to those animals that visit training grounds, exhibitions and other places where there is a mass accumulation of animals. The importance of vaccinating dogs against coronavirus for those animals that are used in breeding is invaluable. To date, protection against coronavirus infection in dogs is provided by the vaccines Duramune DHPPi4L + CvK (Duramune MAX 5 4L / CvK), which is the development of the American company Fort Dodge and the Multican-6 vaccine, manufactured by NPO Narvak, Russia.

The schedule for the use of the Duramune MAX 5 4L/CvK vaccine is as follows: the first vaccination is given to puppies at the age of 2 months, followed by a revaccination 21 days later. Subsequent vaccinations are carried out annually. If the first vaccination was made after the age of three months, revaccination is carried out after 14-21 days.

Multican-6 is administered to puppies at 8-10 weeks of age and again after 21-28 days. Revaccination of puppies is carried out at the age of 10-12 months. Adult dogs are vaccinated once a year. The vaccine is administered intramuscularly in the thigh area in a volume of 2 ml immediately after dissolution. small dogs and ornamental breeds vaccinated in a volume of 1 ml.


This infectious disease can hardly be called one of the deadliest for animals, but this is not a guarantee that other infections will not join it while the body is weakened. Coronavirus infection in dogs is very insidious and sometimes becomes a trigger for a number of problems.

Symptoms of coronavirus in dogs

So, why is the coronavirus in dogs so insidious and dangerous? The virus itself got its name for the processes on the outer shell, very reminiscent of the crown. After infection, he goes to the lower intestine and proceeds to the destruction of the cylindrical epithelium. As a result, we get the following picture: over and over again, the epithelium begins to be rejected and the intestinal villi atrophy. That is why the virus itself may not hit the body hard, but paired with others, it can kill the animal. But fortunately, we have to admit that there are not so many deaths.

The second reason why coronavirus in dogs is an insidious disease is its huge and ubiquitous contagiousness. It's like chickenpox in humans: the animal is perfectly healthy in appearance, but remains a carrier of the disease for a long time. The only difference is that the virus is still active after the dog has been treated and recovered.

As for symptoms in dogs, the classic development of coronavirus is diarrhea and persistent vomiting. Very easy to confuse with . But often these two signs are paired with depression in a dog, often this is a sharp exhaustion of a pet. To confirm our fears, we definitely go to the veterinarian and remember if there were any contacts with other animals about a week ago. It would be nice to know about the well-being of the pets of your friends if you often walk in pairs.

Unfortunately, in the acute phase, there is no way to make any tests that clearly show the presence or absence of the virus. But you can take a blood test, and after a few weeks, observe whether the antibody titer in the blood serum rises.

Treatment for coronavirus in dogs

There is no cure as such. Or rather, there are no drugs specifically for defeating the virus. The task of the dog owner and veterinarian is to prevent joining secondary infection and consequences for the body after fluid loss.

For coronavirus infection in dogs, intravenous infusions are prescribed if there is a dangerous degree of fluid loss. If the owner is confident in the diagnosis (it is known for sure that there was contact with an infected animal), immunostimulants are usually additionally given. It almost always works out. If the stool has changed and bloody fragments have appeared, the dog has an increased or other symptoms, you have to additionally resort to antibiotics.

Coronavirus in dogs: description, symptoms, treatment

Parvovirus-like coronavirus in dogs - description, symptoms, treatment and prevention. Intestinal and respiratory forms of coronavirus infection.

Viral diseases are currently in the stage of deep study. Veterinary and medical virologists are constantly discovering new pathogens as they develop. modern technologies and gain new knowledge in this area. Coronavirus in dogs is no exception. This variety of the causative agent of a viral infection was discovered in 1971, in Germany, when researchers drew attention to the characteristic clinical signs of enteritis in sentinel shepherd dogs, which proceeded in the same way in all animals within the kennel. Let's take a closer look at this disease.

General information about the disease

Like, coronavirus in dogs infects mucosal epithelial cells small intestine, but unlike its relative, it is not characterized by a severe course and in most cases it is asymptomatic. However, in some very common cases, parvovirus and coronavirus simultaneously infect an animal, mutually exacerbating the pathological effect of each other. In addition, it happens that the intestinal form of coronavirus can develop separately in dogs and leads to classic symptoms viral enteritis - diarrhea, dehydration, vomiting and weight loss of dogs.

In 2003, a new strain of canine coronavirus was discovered by UK veterinary virologists, which was later classified as the second, or respiratory type of infection (CRCoV). This type of coronavirus does not develop the intestinal form of the disease, but is localized exclusively in the epithelium of the upper respiratory tract. It is believed that the ancestor of the coronavirus in dogs of the second type are viruses of cattle and humans, which cause similar cold symptoms. Since this respiratory infection transmitted from dog to dog by airborne droplets, re-infection of animals is possible only when they are crowded. It is for this reason that the phenomenon has received the name "kennel cough of dogs" - like people, animals infect each other with a similar "cold", where characteristic symptom is coughing and sneezing.

To date, there are two separate forms of coronavirus infection in dogs - intestinal and respiratory.

Intestinal form of coronavirus infection

The nomenclature of viral diseases in dogs has changed since the discovery of the respiratory form of the coronavirus. It is possible that in the near future other forms of pathogens will be discovered that explain the symptoms in this species of animals, which have not yet been identified.

Concerning intestinal form coronavirus in dogs, over the past almost 50 years, researchers have been able to obtain some information about this disease.

General information about canine coronavirus enteritis

Incubation period illness is from one to three days. Coronavirus is highly contagious and is spread through the feces of sick dogs, which typically continue to shed the virus for six to nine days, but in some cases up to six months after infection, regardless of symptoms and treatment of the infection. Infection of a healthy animal is possible through direct contact with the excrement of a sick dog or household items that could be stained with feces.

The coronavirus is found in dogs all over the world. This pathogen is specific to the entire canine family, both domestic and wild. Among pets, all breeds are susceptible, regardless of age and gender differences. Other species of animals and humans do not get sick with canine coronavirus, they are not carriers.

The virus multiplies inside the cells of the mucosal epithelium of the small intestine and is limited to the upper two-thirds of this organ and adjacent lymph nodes. Infection is generally considered to be relatively mild illness with sporadic symptoms or no symptoms at all when compared with a similar canine parvovirus infection. However, if the coronavirus infects a dog at the same time as parvovirus or other enteric pathogens, the consequences can be much more serious. Only a few deaths among puppies have been registered from the pathological effect of the coronavirus infection alone.

Coronavirus enteritis in dogs - symptoms

The symptoms of the infection are variable and atypical for any given dog. In adult animals, most cases of the disease are asymptomatic, so owners often do not notice any changes in their pet. Sometimes, the symptoms of coronavirus enteritis in a dog can manifest itself in the form of a one-time vomiting, and after a few days - explosive, but short-lived diarrhea. The feces are watery, yellow-green or orange in color. Fever is usually very rare, while anorexia ( strong weight loss) and loss of activity of the animal are more common symptoms of an enteric-type coronavirus infection.

Dog coronavirus. Symptoms characteristic of the disease - explosive diarrhea without blood impurities.

IN rare cases, a dog infected with coronavirus may experience mild respiratory problems associated with a general weakening of the immune system. Puppies often have symptoms of prolonged diarrhea and dehydration. In general, this age group most at risk of developing serious complications associated with the development of the coronavirus. Severe enteritis (inflammation of the small intestine) in puppies, in some cases can cause death.

Among other things, in a dog with coronavirus enteritis, provided there is no additional infection, the following symptoms are distinguished:

  • Loss of playfulness, lethargy.
  • Decrease or complete absence appetite.
  • Frequent urge to vomit.
  • Watery, offensive diarrhea.
  • Weight loss due to general dehydration.

Features of the diagnosis of coronavirus enteritis

When contacting a veterinary clinic, the doctor first of all pays attention to the symptoms. As has already become clear, the symptoms of coronavirus in dogs are similar to many intestinal infections, for example, a particularly dangerous parvovirus infection, which often occurs in combination. If the veterinary clinic has the ability to carry out complex and expensive diagnostic measures on the differentiation of viruses, then it is better to agree to them. In this case, it will be immediately clear what can be expected in the prognosis, and the treatment for coronavirus enteritis will be much less aggressive.

If it is not possible to differential diagnosis, veterinarian will proceed from the most severe variant of the disease - a combination of corona-, parvovirus and canine distemper, so as not to miss the chance to provide timely help. In addition, it will be very useful for the specialist to know whether the dog has been vaccinated against viral diseases, including coronavirus and others.

Treatment of the intestinal form of coronavirus in dogs

Puppies infected with coronavirus infection show the most severe course of the disease and the corresponding symptoms, so maximum attention should be paid to this age group of dogs. Veterinarians know what they are at first glance simple symptoms coronavirus in dogs, like vomiting and diarrhea, can lead to the death of a young animal in just a couple of days. Today, a puppy may continue to frolic and even eat a little food, and tomorrow it may no longer be.

Most adult dogs are able to recover from a coronavirus infection on their own without the need for medication. But such an approach is possible only if accurate diagnosis and the veterinarian will know for sure that apart from the coronavirus, the dog has no other infections.

In some cases, diarrhea can last up to 12 days, followed by soft stools for several weeks. If the infection causes inflammation of the small intestine (enteritis), respiratory problems, and blood poisoning (sepsis), which can occur when a secondary bacterial infection occurs, antibiotics will become an integral part of the dog's treatment.

Severe diarrhea and dehydration will warrant intravenous supplemental nutrition. saline solutions. The need for these drugs is confirmed by appropriate blood and urine tests.

Once a dog has recovered from the coronavirus, there is usually no need to further monitor its health. However, the owner should be aware that the animal may still be a source of the virus that it sheds into environment with your feces. This phenomenon is due to the potential danger of infection with coronavirus enteritis of other dogs.

Disease prevention

There is a vaccine to protect dogs from enteric coronavirus, which is administered to animals in young age, in accordance with the instructions. There is no deficiency in this product, it can be purchased at any veterinary pharmacy or clinic. Practitioners tend to prefer the type of vaccine that has proven itself in their own experience. It is worth emphasizing right away that it is better to purchase vaccines against coronavirus in pharmacies or directly in clinics. Purchasing through online distributors is strictly not recommended.

Because canine coronavirus is a highly contagious infection, the best prevention for him is the immediate isolation of dogs that either show general symptoms disease or diagnosis they have already been made earlier. It is important to maintain cleanliness and hygiene, trying not to allow the dog to come into contact with the feces of other animals during the walk.

Respiratory form of the disease

Although canine cornavirus type 2 has been identified relatively recently, the course of the disease is not characterized by a complex or dangerous current. Compared to humans, dogs show all the signs cold infection. Let us consider in more detail the coronavirus infection of dogs of the respiratory type.

General characteristics of the virus

Canine coronavirus type 2 (RCoV) is capable of causing acute respiratory infection in this animal species and is part of a complex of viruses and bacteria associated with a group of canine infectious diseases. respiratory diseases wearing common name"kennel cough of dogs". This type of virus rarely occurs alone, more often I diagnose it along with others. pathogenic microorganisms such as parainfluenza virus, adenovirus, plague virus, herpes, influenza, bordetellosis, mycoplasmosis and streptococcosis.

How do dogs get infected?

The risk of contracting a respiratory coronavirus infection is very high in cases where a large number of dogs are placed together in a cramped room. Therefore, animals begin to “catch a cold”, as a rule, when they are kept in nurseries, shelters, after visiting exhibitions, and so on. Dogs of all ages and breeds are susceptible to the respiratory coronavirus. Other species of animals and humans do not suffer from this disease. For humans, there is a different kind of coronavirus that can cause cold symptoms.

Like other respiratory infections, "respiratory" coronavirus is transmitted by direct contact from dog to dog, airborne droplets and contact with a contaminated environment. The most effective transmission occurs through direct contact with sick, coughing and sneezing dogs, as the coronavirus is shed in large quantities. Although this type of disease is not dangerous to humans, canine respiratory coronavirus is often found in hand washings, which is transmitted to healthy animals when they try to lick their hands.

Symptoms of Respiratory Coronavirus in Dogs

Most dogs infected with coronavirus infection show benign symptoms:

  • Cough.
  • Sneezing.
  • Mucous discharge from the nasal cavity.
  • Increased body temperature. Occurs rarely.

Some animals have a subclinical infection without any significant severe symptoms coronavirus, but these dogs in any case shed a pathogen into the environment that can infect other animals. It is extremely rare that pneumonia develops, which is observed in the case of a combined infection with other pathogenic microorganisms that have entered the upper respiratory tract.

The incubation period for the respiratory form of coronavirus in dogs is unknown, but it takes about three days for the pathogen to develop. In most cases, symptoms disappear after 1-2 weeks, depending on the dog's immune status, age (longer in puppies and older animals) and the presence of a secondary infection.

Treatment for Respiratory Coronavirus in Dogs

No specific antiviral therapy has been developed against this form of the disease. Treatment consists of supportive care based on clinical signs. Antibiotics may be needed if signs of a secondary bacterial infection are observed. Because canine coronavirus is highly contagious, isolation of infected dogs is essential as the spread of the infection must be minimized.

Quarantine time for sick animals is not precisely determined by research, as it is very difficult to determine the period for which a dog continues to shed the virus after showing signs of recovery. A conservative estimate of the quarantine period is derived based on other respiratory viruses and is at least 3 weeks.

Prevention

Unlike coronavirus enteritis, there is no vaccine against the respiratory form of the pathogen. In addition, it is reliably known that the vaccine against the intestinal form of coronavirus in dogs is not effective against the "cold" form. However, studies have shown that a respiratory infection generates antibodies in the body of a recovered dog, which reduce the risk of reinfection or, by at least, reduce clinical manifestations diseases. The duration of such immunity is unknown.


You got a second dog in the house: we will tell you how to introduce animals to smooth out large quantity problems of interaction between a puppy and an old dog.


Enteric coronavirus in dogs was first discovered in 1971. The incubation period for this form of the disease is 1-3 days. Infection can occur through the faeces of sick animals that continue to shed the virus for 6-9 days, but sometimes even within six months from the moment of infection, regardless of the symptoms of the disease and its treatment. A healthy animal can become infected through direct contact with the faeces of a sick animal or household items that may be contaminated with excrement.

The intestinal form of canine coronavirus is common. Its causative agent is specific to all dogs. All breeds of dogs are susceptible to it, regardless of gender and age. Humans and other animals do not get sick with canine coronavirus and cannot be its carriers.

IN The virus replicates in the cells of the mucous membrane of the small intestine. It occurs in the upper two-thirds of the small intestine and adjacent lymph nodes. The disease is considered relatively mild and manifests itself in the form of sporadic symptoms, but it can also be asymptomatic. In the event that a dog becomes infected with coronavirus and parvovirus at the same time, this can lead to much more severe consequences. However, only a few cases of puppy deaths have been reported from the coronavirus infection alone.

Symptoms of intestinal coronavirus in dogs

Symptoms of the disease are stable and atypical for each individual dog. In adult dogs, the disease is asymptomatic, because the owners often do not notice any painful changes at the dog. In some cases, the symptoms of coronavirus enteritis in dogs are manifested by a single vomiting, and after a few days - a strong and short-lived diarrhea, in which watery excrement that is orange or green-yellow is noted. Fever is rare, while anorexia and loss of activity in the dog are much more common with enteric-type coronavirus.

Very rarely, an animal infected with enteric coronavirus may experience minor respiratory problems that are associated with a drop in immunity. Puppies are observed long diarrhea and dehydration. It is the puppies in most at risk severe complications when infected with coronavirus. Sometimes coronavirus enteritis in puppies becomes very severe, causing death. But do not confuse with enterocolitis in a dog.

Symptoms of coronavirus enteritis in dogs are as follows:

    • lethargy, loss of playfulness;
    • frequent urge to vomit;
    • loss or significant decrease in appetite;
    • very watery diarrhea;
    • emaciation and dehydration.

Diagnosis of the intestinal form of coronavirus

The symptoms of canine coronavirus enteritis are similar to those of many others. intestinal infections, including a very dangerous parvovirus infection, often combined with a coronavirus infection. If the veterinary clinic has the ability to conduct expensive and complex diagnostic procedures differentiation of viruses is better to agree to this. In this case, it will become clear what the consequences may be. With coronavirus enteritis, it is used much less aggressive treatment than in the presence of parvovirus infection.

In the absence of the ability to perform a differential diagnosis, the veterinarian will allow the most severe option - a combination of parvovirus, coronavirus and canine distemper, which will not allow you to miss the opportunity to provide assistance. Also, the veterinarian clarifies whether the dog has been vaccinated against viral diseases, including coronavirus.

Treatment of coronavirus enteritis in dogs

Puppies infected with this disease show the most severe course diseases with corresponding symptoms, therefore this age group requires most attention. Veterinarians know that such simple manifestations of coronavirus as diarrhea and vomiting can lead to the death of a young dog in 2-3 days.

Adults can usually recover from this infection on their own without the use of drugs. However, this is possible only after a diagnosis is made, which will make it possible to reliably find out that, apart from the coronavirus, the dog has no other infections.

Sometimes diarrhea lasts 12 days, followed by soft stools for several weeks. If the infection has led to inflammation of the small intestine (enteritis), blood poisoning (sepsis), and problems with the respiratory tract, which sometimes occurs when there is a secondary bacterial infection, antibiotics will be required for treatment.

At severe diarrhea and dehydration will be required intravenous administration salt nutrient solutions. The need for their use is established on the basis of urine and blood tests.

The owner must remember that the dog may remain a carrier of the virus excreted in the feces into the environment. The phenomenon represents potential danger in the form of a risk of infection with the intestinal form of coronavirus in other dogs.

Prevention of the intestinal form of the disease in dogs

A vaccine against canine coronavirus has been created, which is administered to pets at a young age. shortages in this product No, you can buy it at every veterinary pharmacy or clinic. Usually veterinarians use this type of vaccine. The vaccine should be bought in pharmacies and clinics, it is not recommended to purchase it on the Internet.

Canine coronavirus - very contagious disease. Accordingly, the best preventive measure against it - the isolation of a dog that has general symptoms of the disease or it was diagnosed earlier. Cleanliness should be maintained, excluding the contact of your dog with the excrement of other dogs on walks.

Canine respiratory form of coronavirus

Respiratory Coronavirus in dogs was discovered relatively recently - in 2003. Its course is not heavy and dangerous. When infected with this infection, the animal shows symptoms similar to those of acute respiratory infections in humans.

The virus belongs to the RNA-containing. The name "coronavirus" comes from the presence of many angular crown-like protrusions on the virus shell.

Canine coronavirus type 2 causes an acute respiratory infection in dogs and belongs to a complex of bacteria and viruses that are associated with a group of canine respiratory infectious diseases called kennel cough. This type of virus does not often have a single course, in most cases it is diagnosed in combination with others. infectious diseases- adenovirus, influenza, parainfluenza, herpes, plague, streptococcosis, mycoplasmosis, borreliosis.

How do dogs become infected?

The likelihood of infection with the respiratory form of canine coronavirus increases when many dogs are located in one close quarters. Therefore, the disease is often found in nurseries and shelters, as well as after exhibitions. Respiratory coronavirus affects dogs of both sexes, breeds and ages. Other animals and people cannot get sick with the disease. Famous human species coronavirus that causes cold symptoms.

Like other respiratory infections, the virus is transmitted through direct contact one dog with another by airborne droplets, as well as through contact with an environment contaminated with a pathogen. The most effective transmission of infection occurs through direct contact with sick dogs, which develop sneezing and coughing, as the coronavirus is shed in copious amounts. The form of the disease does not pose a threat to humans, but hand washings often contain canine respiratory coronavirus, which is transmitted by healthy animals when they try to lick human hands.

Symptoms and treatment of the disease

Most dogs infected with this infection show the following symptoms:

  • sneezing
  • cough;
  • nasal discharge;
  • increase in body temperature.

Some individuals have subclinical infection in the absence of any pronounced manifestations coronavirus, however, such dogs shed the infection into the external environment and therefore can infect others. Very rare is the development of pneumonia, which is observed with a combination respiratory coronavirus with others infectious lesions upper respiratory tract in dogs.

The incubation period for canine respiratory coronavirus has not been determined, but the development of the pathogen occurs most often within three days. Mostly, the symptoms disappear after 1-2 weeks, the period is determined by the state of the animal's immunity, its age (the disease in older pets and puppies lasts longer) and the presence of secondary infections.

There is no antiviral therapy against this form of the disease. Treatment of the respiratory form of coronavirus in dogs includes supportive care, which is selected according to clinical signs. The need for antibiotics arises when symptoms of a secondary infection occur. Canine coronavirus is a highly contagious disease, and infected dogs need to be isolated to minimize the spread of infection.

The exact timing of necessary quarantine for sick dogs is not determined by research, as it is extremely difficult to determine the period during which an animal continues to shed the virus after signs of recovery have appeared. A conservative estimate of quarantine time is made based on other respiratory viral diseases, it is at least three weeks.

Prevention

There is no vaccine against canine respiratory coronavirus, unlike the intestinal form of the coronavirus. A vaccine used against the intestinal form is ineffective against the respiratory form of the disease. But some studies have led to the conclusion that a respiratory infection leads to the generation of antibodies in the body of an ill animal that reduces the likelihood of a second infection or at least suppresses the clinical manifestations of the disease. However, the duration of such immunity remains unclear.
