Food Allergy

What is food allergy?

Food allergy is one of the five most common allergies or hypersensitivities know to affect dogs.  Most people know someone who is allergic to certain foods, such as strawberries or nuts.  It is only recently that food allergies have become recognized in dogs.  The signs are usually itchy skin or an upset stomach.  Other more suble changes can also occur including hyperactivity, weight loss, lack of energy and even aggression.

What are the signs of food allergy?

Many dogs will occasionally react to something they ate.  This may be sesitivity to a particular type of food.  The symptoms are often not a true allergy, just mild gastrointestinal upset.  Once you associate the upset with a particular food and avoid it, the problem is usually solved.

Food allergy is different.  Antibodies are produced against some part of the food, usually a protein.  In a pet with food allergy, the immune system overreacts and produces antibodies to substances that it should normally tolerate.  This excessive response is termed an allergic reaction.  Most pets with food allergies have itching rather than vomiting or diarrhea.

Are some ingredients more likely to cause allergies than others?

The most common food allergies in dogs are proteins from dairy products or beef or gluten (from wheat).  Each time a pet eats food containing these substances, the antibodies react and symptoms such as itching, vomiting or diarrhea occur.

These are not the only food constituents that can cause food hypersensitivity.  Virtually any food or ingredient can produce an allergy.  Proteins are the most common cause but other substances and additives can also be responsible.

How is the condition diagnosed?

Feeding an elimination diet is the best way of determining the presence of a food allergy.  This is a hypoallergenic diet which contains none of the ingredients of your pet's previous diet.  Elimination diet trials have to be feed for a minimum of 8 to 12 weeks to see a change.

How is the condition treated?

Once the offending food substance has been identified, a diet is chosen that does not contain these particular ingredients.  Today there are a number of commercially available, palatable, hypoallergenic diets on which the dog can be feed for the rest of her life.

The only cure for food allergy is avoidance.  Some pets may require medication during severe episodes, but most pets can be successfully treated with a hypoallergenic diet.

Is it likely that my dog could develop other food allergies?

It is not uncommon for dogs that have developed an allergy to one particular food to develop other food related allergies.  Additionally, most dogs with food allergies are also allergic to fleas, pollens and other things in the environment.
