Kennel Cough is fairly contagious among dogs. It can also be picked up by cats, rabbits, pigs and guinea pigs. Classically, the infection is picked up when dogs are amongst other dogs such as at the kennel, groomer, dog park, obedience class, animal shelter, vaccination clinic, etc. The coughing usually begins somewhere between 2-14 days after exposure and a dog is considered contagious for 7-10 days after the coughing subsides. Dogs are considered more at risk when under stress or exposed to heavy dust, cigarette smoke, cold temperature or poor ventilation. It is a condition generally treatable with cough suppressants alone or in combination with antibiotics. It can develop into a serious condition when it affects the very young.
