Common Triggers for Food Allergies in Dogs
Before diving into allergies, it’s essential to understand the difference between an allergy and an intolerance.
An allergy is an immune system overreaction to specific substances, which may be found in dog food. However, allergens such as pollen or insect bites can also trigger allergic reactions. When a dog experiences an allergic reaction, symptoms may include itching, skin rashes, digestive issues and other related problems.
In contrast, an intolerance is not an immune response but rather a negative physical reaction to certain food products or ingredients that the dog’s body cannot digest properly. Symptoms of an intolerance typically include gastrointestinal issues such as diarrhea, vomiting, and bloating. In summary, an allergy involves the immune system, whereas an intolerance is related to digestive difficulties.
Most food allergies in dogs are caused by common protein sources such as beef, chicken, or pork. Other triggers include eggs, dairy, and wheat. These allergens are often used in various concentrations in the industrial fodder production. Therefore, transparency about what’s in your dog’s food, and avoiding known allergens, is another reason homemade dog food is recommended.
However, a dog can develop a food allergy to virtually any ingredient, even in small amounts such as a tiny piece of cheese, a treat, or an unidentified ingredient in processed feed. It does not come down to the frequency: Even if your dog gets the improper protein or carb only once a week it could already be enough for an allergic reaction.
