Nobody really knows what it is about chicken or anything else that causes the allergy. But basically its exposure, or over exposure. Just like with peanut butter in humans, dogs have been over exposed to ingredients like Chicken, Wheat, Corn, Turkey and Beef. Its not a coincedence that the most common food allergies in dogs are also the most common ingredients in dog food. It makes it hard to figure out what your dog is really allergic to though as our first step is often to switch to a different formula, lately holistic that doesn't include any of these ingredients. So people(and I don't mean anyone here, as I'm sure most of us know better) tend to think their dog is allergic to say, Chicken and therefore eliminate that ingredient from the food and the allergy dissappears. The trouble is, they may have actually been allergic to the corn or the wheat, which also got eliminated with the switch. So clinical testing or serious elimination diets are really the only ways to conclude what your dog is actually allergic to. And you can't do either of those switching from dog food to dog food.
As a side note, there is a difference between food Allergies and food Intollerances. Allergies cause typical allergic reactions like itching flaking skin, and watery eyes. Intollerances show up with digestive upset. For instance, Crusher, who I once thought was allergic to wheat and corn is actually intollerant of them. So he can have a bit, but not alot. Kind of like someone who can't handle much spicy food, but still sneaks a bite now and then because the small amount won't bother them. An allergy would show up no matter how much was ingested and with extreme cases can show up just by being exposed to the food, like kids who react to the PB on his buddies sandwich without ever eating any himself.
