6 Factors That Cause Dog Food Allergies
Food allergies in humans are a result of intolerance to a particular food ingredient and it happens in the same way in dogs as well. These are also called adverse reactions to food. Adverse reactions are classified as food allergies when the immune system is involved, and food intolerance when it is not. Here are some causes of food allergies in dogs. 1. Higher Quantities of Certain Foods The more a dog is exposed to a particular type of food, the higher are the chances of the dog developing an allergy to it. A dog must be exposed to food to be allergic to it. This is why the proteins present in non-vegetarian food is one of the most common allergens of dogs. 2. Dairy Some dogs find it difficult to digest lactose and end up developing an intolerance to it. Some of the common physical problems due to dairy intolerance include diarrhea, acid reflux, and vomiting. Even if there is an allergy to these products, the symptoms are similar; thus it gets difficult to understand whether the dog has an allergy or is intolerant to dairy. The common difference is that lactose intolerance causes indigestion while allergy can lead to itchiness on the skin and other symptoms.
