Strong Choice
Nutritionally, this is a well-designed limited-ingredient option for puppies, including large-breed puppies, who may need an alternative to more common proteins like chicken or beef. The protein and fat levels are appropriate for growth, and the added DHA, taurine, omega fatty acids, and glucosamine are nice supportive touches. It’s a good fit for owners looking for a duck-based, grain-free formula, though the reliance on potatoes and the grain-free, legume-free approach may not be ideal for every dog long term.

Strengths
- Duck and duck meal as the first ingredients provide clearly named animal proteins to support healthy muscle development in growing puppies.
- Formulated to meet AAFCO nutrient profiles for all life stages, including large-breed growth, with appropriate calcium and phosphorus levels for controlled growth.
- Limited-ingredient design (single main animal protein and simple carb sources) can be helpful for puppies with suspected food sensitivities to more common proteins or grains.
- Includes DHA from fish oil for brain and eye development, plus omega-3 and omega-6 fatty acids, taurine, and glucosamine for additional skin, joint, and heart support.
Considerations
- This is a grain-free formula that relies heavily on potatoes, sweet potatoes, and tapioca for calories; while it avoids legumes, some dogs do just as well or better on diets that include healthy grains.
- Duck is a less common protein but still a potential allergen, so it isn’t automatically hypoallergenic if your puppy already reacts to duck.
- At 25% minimum protein and 12% minimum fat, it’s adequate for growth but not particularly high-protein compared with some other puppy formulas, which may matter for very active or working-breed puppies.

Top 5 Ingredients Explained
01
Duck
Duck is used in pet food primarily as a flavorful animal protein and fat source, commonly included in limited-ingredient or novel-protein formulas for dogs and cats. It supplies high-quality amino acids and energy and can help pets with sensitivities to common proteins, but it is relatively rich in fat (so may be unsuitable for low‑fat or pancreatitis-prone animals), can still trigger allergies in some pets, and requires proper cooking/processing and handling to avoid bacterial contamination.

03
Potato
Potato is commonly used in pet foods as a digestible carbohydrate source and functional binder, supplying starch, fiber, and modest amounts of vitamins (B6, C) and potassium—often included as cooked or dehydrated flakes, starch, or protein concentrates. While it provides energy and helps formulate grain‑free recipes, potatoes are not a primary protein for dogs or cats (and are not nutritionally required for obligate‑carnivore cats), can contribute to excess calories or affect blood glucose in diabetic animals, and must be cooked and free of green skins or sprouts to avoid solanine toxicity; allergies are uncommon but possible.

04
Sweet Potato
Sweet potato is used in pet foods as a digestible carbohydrate and source of soluble fiber, vitamins (notably beta‑carotene), minerals and antioxidants, often helping with stool quality and serving as a binder or energy ingredient. It is generally well tolerated by dogs and can support gut health, but because cats poorly convert beta‑carotene to vitamin A and require preformed vitamin A from animal sources, sweet potato is not a substitute for meat-based nutrients; its relatively high carbohydrate content also means portion control is advised for overweight or diabetic pets and it should be cooked for best digestibility.

05
Tapioca Starch
Tapioca starch is a purified carbohydrate used in pet foods mainly as a thickener, binder and easily digestible energy source, contributing virtually no protein, fat, vitamins or minerals. It is low‑allergy and gluten‑free, but because it is a high‑glycemic, low‑nutrient filler it should be limited in diets for overweight or diabetic pets and not relied on for essential nutrition.
