Proteins are the most common food allergens in dogs. However, dogs are not born with allergies to specific proteins in their diets. They develop these allergies over time.

When dogs feed on the same food over and over, the body may become less equipped to break down that particular food. They, therefore, become intolerant to such foods. So, the more you feed your dog a specific diet, the more likely they will develop intolerance to that particular food.

Symptoms of Protein Allergies in Dogs

Protein allergies can have dangerous to your canine. It is, therefore, essential to understand the symptoms of protein allergies in order to seek medication.

The first sign of protein allergies is usually vomiting. Other signs may include; itching, diarrhea, excessive licking, facial swelling, runny nose and many more.

Common Protein Allergens in Dogs

To prevent protein allergies in your dog, you must understand the protein that dogs are most allergic to.  Below are the common proteins that dogs are allergic to:

  1. Beef

Beef is one of the most common foods directly fed to dogs. It is also a common ingredient in most dog foods and treats, which may be the reason why most dogs are allergic to it. According to BMC Veterinary Research, beef constitutes to about 34% of food allergies in dogs.

2. Dairy Products

Another common protein food allergen is dairy products. About 17% of dog food allergies result from eating dairy products. Most dogs have difficulties digesting lactose, a component found in milk.  Lactose intolerance on dogs can lead to various symptoms, including vomiting, diarrhea, skin itchiness, among others.

3. Chicken

Just like beef, most dogs are allergic to chicken because it is a common protein. The dog’s immune system perceives chicken as an intrusive substance and reacts to it aggressively causing the allergic reaction. The common symptom of allergies caused by chicken is skin reactions around the face and toes.

4. Soy

Soy is a source of protein in most dogs’ diets. However, when some dogs eat soy, their defensive mechanism causes a hypersensitive reaction that may result in itching. Besides being an allergen, soy is reported to cause health issues like growth problems, thyroid, reproductive issues and liver diseases.

5. Lamb

Lamb is labeled as a glycoprotein that brings allergic responses to dogs who have developed a sensitivity to glycoproteins. Lamb allergies make up 5% of reported dog food allergies. In most cases, symptoms of lamb allergies in dogs are usually subtle for a long time.

There are many other proteins that cause food allergies to dogs, including eggs, pork, and fish. Since dogs develop allergies with time, it essential to switch your source of proteins to reduce the risk of developing further protein allergies.
