With the advent of lamb and rice diets many people feel that they are preventing or treating food allergies. The fact is that nothing could be farther from the truth. The entire process of a pet being sensitized to a particular agent in food and the complicated antibody response that occurs in the intestinal tract in pets with food allergies are not very well understood. Despite our lack of understanding of the actual disease process, there are many things that we do know including the symptoms, how to diagnose food allergies, and also how to treat them in dogs and cats. Dogs and cats develop allergies to those foods that are most frequently fed.
Food allergies affect both cats and dogs.
Unlike atopy there is no strong link between specific breeds and food allergies. Food allergies affect both males and females and neutered and intact animals equally. They can show up as early as five months and as late as 12 years of age, though the vast majority of cases occur between 2 and 6 years. Many animals with food allergies also have concurrent inhalant or contact allergies. There is a distinction that needs to be made between food allergies and food intolerances.
