What is "korovina" in dogs? - briefly
Korovina, also known as cowherd disease or bovine leukemia, is a viral infection that primarily affects cattle but can also be transmitted to dogs through raw milk consumption. In dogs, it can lead to symptoms such as fever, anemia, and enlarged lymph nodes.
What is "korovina" in dogs? - in detail
Korovina, also known as kennel cough or canine infectious tracheobronchitis, is a highly contagious respiratory disease that affects dogs. It is characterized by a harsh, dry cough that often sounds like a honk or bark, hence the name "korovina" which translates to "cow-like" in some languages. This condition is caused by a combination of factors, including bacteria and viruses, with Bordetella bronchiseptica being one of the primary bacterial agents.
The disease spreads rapidly through respiratory secretions, making it easily transmissible in environments where dogs are in close contact, such as kennels, dog shows, or pet stores. Puppies and senior dogs are particularly vulnerable due to their weaker immune systems. Symptoms typically appear within five to ten days after exposure and can last for several weeks.
In addition to the distinctive cough, other symptoms may include sneezing, runny nose, lethargy, reduced appetite, and in some cases, a mild fever. While korovina is generally self-limiting and resolves on its own within a few weeks, it can lead to complications such as pneumonia in severe or immunocompromised cases.
Diagnosis is usually based on clinical signs and history of exposure, although laboratory tests may be performed to identify the specific pathogens involved. Treatment primarily focuses on supportive care, including rest, hydration, and managing symptoms such as cough. Antibiotics are often prescribed to prevent or treat secondary bacterial infections, particularly if the dog is immunocompromised or shows no improvement within a reasonable time frame.
Vaccination is an effective preventive measure against korovina. Available vaccines typically target Bordetella bronchiseptica and other common pathogens associated with the disease. Regular boosters are recommended, especially for dogs frequently exposed to other animals in boarding kennels or shows. However, it's important to note that while vaccination reduces the severity of symptoms and lowers the risk of infection, it does not provide complete immunity.
Owners should also take precautions such as minimizing contact with infected dogs, ensuring proper ventilation in indoor spaces, and maintaining good hygiene practices to reduce the spread of the disease. Early veterinary intervention is crucial for managing symptoms and preventing potential complications.
