BloomingPaws Vet Clinic would like to share some facts on the health and care of dogs and cats infected with Canine Adenovirus.
Canine adenovirus (CAV-2) is a DNA virus that is commonly
associated with canine infectious tracheitis, also known as ‘canine cough’.
Transmission of Canine Adenovirus
- Spread directly from dog to dog through infected respiratory secretions (coughing/sneezing) or by contact with contaminated feces or urine.
- Clinical symptoms will occur 3-10 days after exposure.
Clinical Symptoms for Canine Adenovirus
- Dry, hacking cough
- Retching and gagging
- Coughing up white foamy discharge
- Conjunctivitis – sometimes
- Fever, lethargy, anorexia
- Nasal discharge
- The infections is most times self-limiting; however, in some cases (young puppies), it can lead to pneumonia.
Diagnosis for Canine Adenovirus
- Presumptively based on clinical signs and patient history (vaccine status and possibility of exposure)
- Rarely specific testing is done for this particular virus.
Treatment for Canine Adenovirus
- There is no cure for canine adenovirus. Treatment is aimed at supportive care which includes maintain hydration status, nutritional support and possibly antibiotics for secondary infections.
- Isolation from other dogs
Prevention of Canine Adenovirus
- Vaccination. However, it is important to realize that the vaccine does not completely prevent dogs from contracting CAV-2. Rather, the vaccine limits the severity of infection so that vaccinated dogs typically experience a milder form of the disease. The CAV-2 vaccine also protects against canine adenovirus type 1 (CAV-1) which causes canine infectious hepatitis—a dangerous and potentially fatal infection affecting the liver.
- This vaccine is given as part of the puppy series and then a booster is given yearly to every 3 years thereafter.
Canine Adenovirus is still commonly found in the Bloomington, IN area in
those dogs that are unvaccinated or under-vaccinated. With the current use of
the vaccine, the severity of the infection is lessened significantly.
