Symptoms of Food Allergies in Dogs
Food allergies are a common problem that often affects pets. According to PetEducation.com, food allergies account for approximately 10 percent of allergies in both cats and dogs. Dogs often develop food allergies to products containing beef, chicken, dairy products, eggs, pork, soy, corn and fish. Preservatives can also cause food allergies.
Food allergies can develop in dogs of any age or breed. A dog can suddenly develop a food allergy even if the food previously did not cause any problem. If there is a change in ingredients in a dog's regular food, a food allergy may result. Fortunately, food allergies can usually be easily corrected by making the necessary dietary changes.
