There are three main types of dog allergies, skin allergies, food allergies and flea allergies. They can sometimes be very difficult to diagnose because they don’t exhibit as symptoms that you would find consistent with what you would expect from an allergy. Things like diarrhea and vomiting from your dog could be an allergic reaction.

Treatment of your dog’s allergies can sometimes also be very difficult to carry out, particularly if you’re having trouble working out exactly what it was that triggered the allergic reaction. Methods of changing the dog’s environment or removing items from the dog’s immediate surroundings may work as could altering your dog’s diet.

Whatever course of action you choose it should first be discussed with the vet and any action should be carried out under his supervision or direction.
