Your vet may recommend you put your pooch on an elimination diet, which is a diet that will allow you to gradually add more foods until you discover what your pup may be allergic to. If this doesn't work he may be allergic to a medication, or just have outside allergies. You'll have to play detective and communicate well with your vet.

Many seemingly random symptoms can be signs of a food allergy in a dog. These include:
