What Should I Do If I Think My Dog Has Allergies? :
Visit your veterinarian. After taking a complete history and conducting a physical examination, he or she may be able to determine the source of your dog’s allergic reaction. If not, your vet will most probably recommend skin or blood tests, or a special elimination diet, to find out what's causing the allergic reaction.
