Short answer: A "novel protein" is simply a protein your dog has rarely or never eaten — and rabbit and duck are two of the most useful ones. Because most commercial foods rely on chicken and beef, many dogs have never been exposed to rabbit or duck, which makes them go-to options for itchy, sensitive dogs and for vet-guided elimination diets.
What "novel protein" actually means
Food sensitivities develop through exposure: a dog eats the same protein daily for years, and in some dogs the immune system starts reacting to it. A novel protein sidesteps that history — it is new to your dog's immune system, so it is less likely to trigger a reaction. "Novel" is personal, not absolute: duck is novel only if your dog has not been eating duck.
The usual suspects
In published veterinary studies, the ingredients most often reported in dog food sensitivities are the most common ingredients in dog food: beef, dairy, chicken, and wheat top the list. That is not because they are "bad" — it is because nearly every dog eats them constantly.
Signs it might be the food
- Itchy skin, paws, or ears that keep coming back year-round (seasonal itching points more to environmental allergies)
- Recurring ear infections
- Loose stool, gas, or an on-and-off sensitive stomach
Only a vet-guided elimination diet — one novel or hydrolyzed protein, fed exclusively for 8–12 weeks — can confirm a food sensitivity. And during a trial, treats count: one chicken biscuit can reset the clock. Trial treats must match the trial protein.
Why rabbit?
Rabbit is lean, mild, and low in fat — easy on sensitive stomachs — and it has historically been rare in commercial dog food, so most dogs are truly naive to it. It is a classic elimination-diet protein for exactly that reason.
Why duck?
Duck is rich and highly palatable — picky dogs that refuse "diet food" usually accept duck — while remaining a genuinely novel protein for most dogs. It is also naturally rich in iron and amino acids.
How to use novel proteins at home
- For a vet-run elimination trial: choose single-ingredient treats in the trial protein only.
- For everyday rotation: rotating proteins every few weeks spreads exposure and keeps meals interesting — a practical habit for dogs with mild sensitivities.
- Introduce slowly: mix a little of the new protein in over several days and watch skin and stool for two weeks.
FAQ
How long before I see improvement? — Skin signs of food sensitivity typically need 6–8 weeks on the new protein before you can judge; stomach signs often improve sooner. Judge after the full trial, not the first week.
Is duck good for itchy dogs? — It can help if the itching is driven by a sensitivity to the dog's usual protein, such as chicken or beef. Duck is not a treatment for environmental allergies, which are more common — if itching is seasonal, talk to your vet about allergy testing.
Can I rotate proteins instead of doing a full elimination diet? — For mild, occasional sensitivity, rotation is a reasonable everyday strategy and it is how many pet parents manage it. For chronic itching or ear infections, a proper elimination trial gives a real answer instead of guesswork.
Honest labels, from our shelf
Our freeze-dried duck breast is a single ingredient — 100% duck — which makes it a clean fit for elimination trials and sensitive dogs. Our rabbit bites pair rabbit with chicken and carrot: a great everyday rotation treat, but if your vet is running a strict chicken-free trial, the duck breast is the right pick. We would rather tell you that than sell you the wrong bag.
