Why are my dogs coughing so much after new AC installation?

Updated On September 23rd, 2025

Pet's info: Dog | Goldendoodle | Male | neutered | 7 years and 5 months old | 72 lbs

We recently had forced air AC installed in our house and ever since we started running it, both of our dogs have been coughing a whole lot. They are both up to date on bordatella vax and are showing no other signs of illness. Does this seem like something that could be a result of the difference in the air in the house due to the new air conditioning?

Air conditioning units work by condensing the air which causes it to lose moisture which in turn makes it a lot drier. This will often cause coughing as it is more irritant to the airway, and it can contribute to chest infections. I would consider using it less often or letting the dogs spend more time outside. If they continue coughing it could be an infection so go to the vet.
