When a dog has an allergy, it may sneeze, scratch or lick itself. It sometimes has a rash or rubs its face. Often the dog is allergic to pollen, fleas, food, chemicals or fabric. Many veterinarians suggest over the counter (OTC) allergy aids for temporary relief. These simple remedies require no prescription. However, not all dogs respond the same to OTC treatments, so check with a veterinarian for suggestions and dosage.
