Hypoallergenic Dog food is needed by your dog if you are unable able to pinpoint which food is causing the allergy or if your pet has multiple sensitivities. When your dog suffers from any type of food allergy, common sense dictates changing the diet to exclude the allergic food.
Since your dog can be allergic to any of the ingredients in the normal packaged dog food – any of the major ingredients, preservatives, colorings, flavorings, or any of the multitudes of chemicals that go into the preparation of the dog food, you would definitely need to start giving your pet a diet prepared to exclude allergy-causing foods and chemicals.
Dog food ingredients can be difficult to understand. It may look healthy at first glance but a closer review might reveal a different story. Remember, no dog food can possibly be appropriate for every life stage, lifestyle or health condition. So, choose wisely. And when in doubt consult a veterinarian for help.
