How to tell if your dog has a food allergy ? Allergy to dog food.
Allergy to dog food
True food allergies are less frequent than food allergies. Food allergies reflect an immediate immune response. A classic example of a food allergy is anaphylactic shock that appears after eating peanuts or after a bee sting: Once a person or animal comes into contact with the allergen, their airways are closed and they cannot breathe. This response is fast. The antigen causes an immediate and sometimes life-threatening reaction due to hypotension and shock.
A less severe but still serious form of the allergic reaction is observed with skin signs such as hives, facial swelling and itching. It can be accompanied by gastrointestinal signs, such as severe vomiting and/or diarrhea. These signs occur fairly quickly but less so in an allergic reaction.

On the other hand, a food allergy (or intolerance) is usually a chronic condition and often does not involve an immune response. It is generally a cumulative response to the offending agent.
Although generally not life threatening, food sensitivities can affect many different aspects of a dog's physical health. Common signs of a food allergy include:
Gastrointestinal signs: often next-day diarrhea with or without vomiting.
Skin tags: weak skin or itchy coat. Chronic ear or foot infections (yeast and/or bacterial)
What to do if you suspect your dog has a food allergy
The first step in providing proper relief to dogs with food allergies is to consult your veterinarian to determine the exact problem. There are tests available to help detect the causative agent(s). With this information, you and your vet can begin to find a feeding plan for your dog with a diet that matches his body.
If your primary vet is unable to resolve the issue, you may be referred to a veterinary dermatologist. Finding the right answer may not happen quickly, but it is well worth the effort throughout a dog's life.
