Buying Guide
What Qualifies as a Novel Protein?
A protein is ‘novel’ specifically for a given dog – not for all dogs. Venison may be novel for a dog that has only eaten chicken and beef, but not novel for a dog that has eaten venison-based food for years. The key is finding a protein your specific dog has never been exposed to.
The Most Exotic Novel Proteins
When common novel proteins (duck, venison, rabbit) have all been tried, more exotic options include: kangaroo (New Zealand and Australian sourced), alligator (Cajun-sourced), wild boar, bison, ostrich, and even insect protein. These represent the last resort for dogs with severe multi-allergen responses.
Novel Protein Rotation Strategy
After successfully managing allergies with a novel protein, some veterinary dermatologists recommend a protein rotation strategy: cycling through 2-3 tolerated proteins every 2-3 months to prevent developing new allergies. This is preventive, not reactive.
Single Protein vs. Single Ingredient
A novel protein food should use a single animal protein source throughout – not just as the primary ingredient. Check for hidden protein sources in the ingredient list: chicken fat, beef broth, pork liver flavoring, and other secondary proteins can contaminate a novel protein diet.
Frequently Asked Questions
What is the most truly novel protein for dogs?
Kangaroo and alligator are among the most novel proteins commercially available, as they are rarely used in any dog food. Most dogs in the US and Europe have never been exposed to these proteins. For dogs that have tried duck, venison, rabbit, and still react, kangaroo or alligator are logical next steps.
How do I find a dog’s novel protein?
Review every food, treat, supplement, and flavored medication your dog has consumed. Any protein source they have eaten is no longer novel. Novel proteins must be ones they have genuinely never encountered. This requires a comprehensive diet history.
Can novel protein diets be complete and balanced?
Yes. Commercial novel protein diets from reputable brands are formulated to meet AAFCO nutritional requirements. They contain added vitamins and minerals to compensate for any nutritional gaps from the unusual protein source.
How long before I know if a novel protein is working?
Allow 8-12 weeks on a strict novel protein diet to assess efficacy. Skin symptoms typically improve before complete resolution. If no improvement occurs after 12 weeks, the dog may have environmental allergies in addition to food allergies, or may have been exposed to the novel protein through treats or medications.
