My dogs have kennel cough. Will they keep passing it back and forth?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 40 lbs

Adopted a puppy from shelter, brought home & he started acting lethargic, heavy/labored breathing, sneezing, hacking/coughing, runny nose. my 6yr old dog now has the same symptoms and my puppy seems to be getting a little better. Vets just tell me its nothing. but i assume it's kennel cough. Puppy was on anitibiotics now my adult dog is on them, will they keep passing it back and forth?

They should not pass it back and forth once they have recuperated from this strain of infection kennel cough is caused by a variety of viruses and bacteria. It can take up to 6 weeks to pass. Usually it is an uncomplicated infection. Unfortunately kennel cough is rampant in shelters.
