My 8 years old healthy Labrador is down with Wheezing,Dry Cough accompanied by episodes of fainting ( syncope and not seizure !) . Fainting has been there occasionally but wheezing,gagging and breathing discomfort has increased over the last 2 months or so ! Vet feels its acidity,reflux related and has prescribed ; Pantaprazole,Augmentin 625 and PPF! Eating healthy but at times declining and activity has come down,may be due to hot and humid conditions these days ! Breathing difficulty is seen with belly heaving,elbows sticking out,head down stretching ahead and gagging as if trying to throw out! Please help.
