Detecting food allergy: Your dog reacts with these symptoms

If your dog is constantly scratching, biting or chafing, fleas do not always have to be blamed. Even a food allergy can be the trigger of itching. The symptoms are nonspecific and are therefore often misinterpreted.

Itching in the dog is often associated with a flea infestation or other parasites. Scratching and biting on various parts of the body is one of the most common symptoms of food allergies.

Food allergy causes itching and skin problems

The itching is usually accompanied by sore skin, caused by the constant scratching of the dog. In particularly bad cases, the skin can become chapped and it can be caused by entering viruses or bacteria painful inflammation. However, itchy skin rashes can also be triggered by other allergies or skin diseases, so that their appearance alone can not give a clear indication of a food allergy.

Other symptoms of food allergy

Just as frequently, a food allergy manifests itself through gastrointestinal problems. Vomiting, diarrhea, bloating or loss of appetite, which often recur, indicate chronic gastrointestinal irritation. Behind it allergic reactions to ingredients of the feed can hide. However, the same applies here: the symptoms can have many other causes in addition to food allergy.

To find out which problem is behind the complaints, a detailed medical history by the veterinarian is necessary. The blood and the organs are examined in detail in order to exclude other diseases. Usually, the dog is then placed on a special exclusion diet, where he may only take food with certain ingredients. If the symptoms improve during the diet, a food allergy is very likely.
