Hello, I'm hoping someone can help me... I have two dogs, they are both 11 yrs old and have been healthy their entire lives. About a month ago, one of them began coughing- a dry hacking cough that comes on suddenly or after what seems like some difficulty breathing. She is a jack russell terrier normally around 20lbs and has gained about 3.5 lbs in the past couple months, which I'm not sure has anything to do with her cough.
Anyway, she's been to the vet several times, they've done a EKG and chest x-ray. They ruled out kennel cough and thought maybe it was a cold turned pneumonia, so they prescribed antibiotics and anti-inflammatory- first for 10 days(5 for anti inflam), then again for 10 days (5 for anti inflam). She was better and stopped coughing during the last antibiotic treatment course, but its back again. The vet now thinks its an allergy. To me, that diagnosis sounds strange since she has been super healthy free of any other issues for 11 yrs.
Anyone had a similar situation and any advice about what this health issue is?
