Have a Wire Fox Terrier - 9 yrs. old. He began throwing up bile in the morning after he wakes a few months ago, off and on. Could this be a allergy to the food he's eating? He eats Nutro Lite dry with Nutro Lite wet in morning, and just Nutro dry in eve. Am puzzled by this.
My vet said give him an acid reducer in his food in morn., which I did, but didn't seem to make any difference.
Sometimes you can run 100 different tests and never find the reason for this but I agree with your vet. vetcare
