Food intolerance can have a range of symptoms. Some of the more common ones are: Vomiting Diarrhoea Tummy pain (causing things like abnormal stretching or standing with an arched back) Loss of appetite Lack of energy or lethargy Gas (flatulence) Red or itchy skin, especially around back end, face, groin and between front legs and body (axilla) Hair loss Repeated ear problems and skin infections Coughing and wheezing may sometimes be seen. Food intolerance is usually suspected based on the symptoms. Tests may be needed to rule out other diseases: Faeces tests to rule out intestinal parasites and some infections Blood tests to rule out diseases of internal organs, such as pancreatitis or liver disease Skin scrapes to rule out mites. The final diagnosis of food intolerance is usually achieved by doing a strict diet with a special food for 6-8 weeks. If vomiting has been a problem, a short period (4-12 hours, depending on age and other factors) on an empty stomach may help things settle. Small, frequent meals and an easy to digest diet for a few days will feed the healing of the gut while reducing the symptoms. Chicken/white fish and white rice can help in many cases if your dog is not intolerant to these.

The clinical signs of a food allergy are usually itchy skin, paws, or ears or digestive disturbances such as vomiting or diarrhea. Other more subtle changes can also occur, including hyperactivity, weight loss, lack of energy, and even aggression. The most common food allergens in dogs are proteins, especially those from dairy, beef, chicken, chicken eggs, soy, or wheat gluten. Virtually any food ingredient can produce an allergy, however. To be a true elimination trial, this special diet must not contain any ingredients that your dog has eaten in the past. If your dog's allergy symptoms resolve while on the food trial, the next step is to perform a food challenge by re-introducing your dog's old food. If your dog's symptoms resolve with the food trial and return within one week of a food challenge, your dog has been definitively diagnosed with a food allergy.
