Quick answer: If you suspect your dog is sensitive to a certain type of meat, don't get a blood test—not because it's expensive, but because it's inaccurate. The American College of Veterinary Dermatology (ACVD) does not recommend serum IgE/IgG food allergy testing, because it is a perfectly normal immune response for a healthy dog to produce antibodies to food proteins, giving an extremely high false-positive rate. As of 2026, the elimination diet trial remains the only validated method for diagnosing food sensitivity. The correct approach has 6 steps: Step 1: Rule out other causes first—flea allergy and environmental atopic dermatitis are far more common than food sensitivity; running a food trial before dealing with fleas is a waste of time. Step 2: Understand why blood tests are unreliable—serum, saliva and hair testing are none of them recognised by veterinary dermatology. Step 3: Choose a single animal protein your dog has never eaten before—beef (34%), dairy (17%), chicken (15%) and wheat (13%) are the most common allergens and should be avoided. Step 4: Follow it strictly for 8–12 weeks—during this period zero treats, zero human food, zero flavoured medications; one slip and you have to start counting again. Step 5: Confirm…
