A highly infectious upper respiratory disease caused by various airborne bacteria and virus. It spreads easily and quickly among dogs in close quarters as when they are confined to kennels or shelters. Symptoms may include a dry cough, sneezing, gagging, and vomiting. Sometimes, but not always, the dog may have a fever. Dogs normally recover after a few weeks. The primary concern is that secondary conditions such as pneumonia may develop.
Vaccinations are available that can provide some protection but are not foolproof. Much like flu in humans, there are many causes and it is difficult for a vaccine to protect against all the possible pathogens that exist. If treatment is necessary, antibiotics and cough suppressants are used.
