Buying Guide
Hydrolyzed vs. Novel Protein for Allergies
Hydrolyzed protein is broken into fragments too small for the immune system to recognize as allergens. Novel protein foods use intact proteins the dog has never consumed. Both work, but hydrolyzed protein diets offer higher certainty of allergen avoidance.
Common Allergens in Medium Breed Dogs
Beef, chicken, dairy, and eggs account for the majority of canine food allergies. If your medium breed has been eating chicken-based food, duck or venison would be appropriate novel protein choices.
The Elimination Diet Process
Strictly hypoallergenic food for 8-12 weeks. No treats, flavored supplements, or human food. After the elimination period, reintroduce one ingredient every 2 weeks to identify specific allergens.
Prescription vs. OTC Allergy Diets
For severe allergies, prescription hydrolyzed diets offer the most rigorous allergen avoidance. OTC limited ingredient diets are effective for mild-to-moderate allergies and don’t require a veterinary prescription.
Frequently Asked Questions
How long does an elimination diet take for medium dogs?
8-12 weeks. Cheating even once (a single treat) can reset the process. Track symptoms weekly in a diary to document improvement throughout the trial.
Can medium breed dogs develop new food allergies as adults?
Yes. Dogs can develop allergies to proteins they have eaten for years. Repeated exposure sensitizes the immune system over time – which is why novel protein diets work by using proteins the immune system has not been previously sensitized to.
Is duck or venison better for a medium dog with allergies?
Both are excellent novel protein choices if your dog has not eaten them before. Duck tends to be more widely available and palatable. Venison is more exotic and better if your dog has been exposed to duck previously.
Do I need a vet prescription for an allergy diet?
Prescription hydrolyzed protein diets require a prescription. OTC limited ingredient diets and novel protein foods do not. For mild symptoms, OTC options are a reasonable starting point. For severe allergies, work with your vet.
