A food allergy is a reaction by an individual animal to a particular substance in their food. This occurs when the bodies’ response to normal food becomes ‘confused’, causing abnormal reactions. Frequently the food has been part of the diet for a long time. We cannot stop this abnormal reaction so the only effective treatment is to avoid eating the food that causes the problem.
The most common causes of food allergy in the dog include beef, mutton, chicken, wheat, corn, soy, dairy foods and eggs. Occasionally chemicals such as preservatives, additives or food dyes are also the culprit.
The most common causes of food allergy in the cat include fish, beef and dairy products.
