My 16 year old terrier mix, Beavis, has had a cough for over a year. My vet says it is from his tonsils and recommends antibiotics and
prednisone as needed. It doesn't help alot but does help some. He has had a chest x-ray and only has a small murmur, which isn't causing the cough. Also had his teeth cleaned within the past year. His cough is worse in the morning and with exertion ie barking. Being 16, he really doesn't exert himself much. But two questions: One, what else could his cough be from? Should I be worried? Also, I know there is a human cough medicine that would be safe for him, but I can't remember which one. Anyone know what I could give him to ease his coughing? Thanks in advance.
