Not many people realize that just like humans, dogs also have allergies to foods. Although there are a large variety of things dogs may be allergic to often times the symptoms are the same. A few symptoms to look out for include itchiness, diarrhea, vomiting, swelling on the face or body, itchy ears and sneezing. Some other rare and more serious symptoms include breathing issues, seizures and weight loss.

Now that you know the symptoms continue reading for more information on the top common dog food allergies:

1. Wheat

Just as with humans who suffer from wheat and gluten intolerance there are also dogs that suffer from gluten or wheat allergies. Wheat can be found in most brands of dog food. Although most dogs can digest wheat and it is often a good source of grains there are some who may have an intolerance for it. Some signs include vomiting and diarrhea after eating. To avoid this issue try feeding pups gluten free dog food.

2. Beef

Although for some it may be hard to believe there are many dogs who suffer from a beef allergy. Not only does their stomach have a harder time processing the beef it can also affect other parts of the body. Some common symptoms include ear infections, rashes, diarrhea and vomiting. Although it may be a little bit harder to find there are many dog foods that are plant-based especially for dogs who have a beef intolerance.

3. Dairy

Dairy is one of the most popular food allergens not only in humans but also in dogs and even cats. Many dogs have a hard time digesting milk products. Milk allergy symptoms often include diarrhea as well as vomiting and possibly even a rash.

4. Corn

Although corn is one of the top key ingredients in most dog food brands it can be a serious allergen for many dogs. Corn is not only harder to digest but it also lacks all of the nutritional benefits that other typical vegetables have. Some common symptoms of corn allergies include itching, vomiting, abdominal cramps and diarrhea.

5. Eggs

Some dogs have an allergic reaction to eggs which many researchers trace back to the high amounts of protein that can be found in eggs. Dogs often have a hard time breaking down protein especially in large abundances. Not only can it affect a dog’s immune system but it can also affect their overall health and well-being. Some key symptoms of egg allergies in dogs include itching, abdominal pain, diarrhea and even vomiting.

Over all these are just a few of the many different things that dogs can be allergic to. Dogs can also be allergic to chicken, soy, peanuts, cheese, yogurt, beans and even certain types of fruits and vegetables. For any dog showing signs or symptoms of an allergy it is best to have the pet checked out by a veterinarian to ensure nothing such as a food allergy or something more serious is going on.
