Those mysterious symptoms could mean your dog or cat has a food allergy. Pets can become allergic to protein in food, treats or table scraps. They can develop skin problems, such as rashes, itchiness, reddened ears and hair loss, or intestinal problems, including vomiting and diarrhoea.

The symptoms of food allergy can look like those caused by allergies to fleas, plants or pollen. Just like people, pets can be allergic to bites and some plants and they can have "hay fever." Usually though, allergies to pollen and plants show up during the spring and summer. Food allergies can occur any time of the year.

If your dog or cat does have a food allergy, it can be easily controlled. A new line of pet food has been developed using a process called hydrolysation. This same process is also being used to manufacture formula for human babies who are allergic to milk protein. It's the most innovative advancement yet for managing food allergies in pets.
