How to tell if a dog is allergic to food: signs and symptoms

Food hypersensitivity in pets is often disguised as dermatological diseases or parasitic infestations. The owners unsuccessfully treat itching and dandruff, unaware that the cause of the disorder is the animal's daily diet.
Timely recognition of specific clinical manifestations helps to adjust the dog's menu in time and avoid chronic complications from internal organs. Diagnosis requires a systematic approach and the exclusion of other possible pathologies.
The main skin manifestations of food allergies
Severe itching becomes the first signal of intolerance to a particular protein in the feed. The animal begins to continuously comb its ears, muzzle, armpits and groin area, damaging the skin until it bleeds.
Bald spots form in place of permanent combs, the skin darkens, thickens and acquires a characteristic unpleasant odor. The following local symptoms indicate that the body is affected by allergens:
- redness of the skin between the toes and their constant licking;
- frequent otitis media, accompanied by the release of dark exudate;
- the appearance of a small rash on the hairless areas of the abdomen.
Such dermatological disorders require examination by a veterinary dermatologist to rule out fungal infections. Without eliminating the food trigger, topical treatment with ointments gives only a temporary relieving effect.
Gastrointestinal symptoms
Food intolerance is often manifested by chronic digestive disorders of varying severity. The dog's intestines react to foreign protein by malabsorption of nutrients and inflammation of the mucous membrane.
The regeneration of mucosal cells slows down, which leads to systemic failures. To accurately record violations, the owner must keep a detailed observation diary, noting in it:
- meal time and exact portion composition;
- frequency of bowel movements and consistency of stool;
- the appearance of vomiting or rumbling in the abdominal cavity.
The systematization of this information allows the veterinarian to quickly identify a potential irritant when analyzing the diet. Digestive problems are often accompanied by a general depression of the animal's condition and a decrease in activity.
The exclusion diet method for diagnosis
The only reliable way to confirm the diagnosis is to conduct an elimination diet under the supervision of a doctor. Laboratory blood tests for food allergens in dogs often show unreliable results.
All the usual sources of protein and carbohydrates are completely excluded from the pet's diet for eight weeks. The animal is transferred to new types of meat or hydrolyzed veterinary feed, broken down to safe amino acids.
If the signs of itching and digestive disorders disappear during the specified period, a provocative test is performed, returning one old product. The return of symptoms within a few days definitively confirms the nutritional nature of the pathology and helps to form a safe lifelong menu. 1xBet met à votre disposition tout ce dont un parieur moderne a besoin.
