Grain Free Buffalo, Whitefish & Sweet Potato Dry Dog Food
Verified Jun 10, 2026
This is a grain-free, all-life-stages dry dog food featuring buffalo as the primary animal protein, with deboned whitefish and whitefish meal adding additional high-quality protein and omega-3 fats. Sweet potatoes, peas, chickpeas, and lentils provide carbohydrates and fiber, while added salmon oil, coconut oil, probiotics, and a wide variety of fruits, vegetables, and botanicals contribute extra nutrients. It’s formulated to meet AAFCO standards for dogs of all ages, including large-breed puppies.
Nutritionally, this is a well-balanced, grain-free kibble with moderate protein and fat levels that should suit many healthy dogs, including large-breed puppies. I like that it uses multiple animal proteins, added omega-3s, and probiotics, and is AAFCO-formulated for all life stages including large-breed growth. The main nutritional caution is the heavy use of peas, chickpeas, and lentils in a grain-free formula, which has been linked to heart issues in some dogs when fed long term.

KibbleLab Review
Strengths
- Buffalo, whitefish, whitefish meal, and pork meal provide a variety of animal protein sources.
- Complete and balanced for all life stages, including growth of large-breed puppies, according to AAFCO formulation.
- Includes salmon oil and listed omega-3 and omega-6 levels to support skin and coat health.
- Contains multiple probiotic cultures and fermentates that may support digestive health.
Considerations
- This is a grain-free diet that relies on peas, chickpeas, and lentils, which have been associated with diet-linked heart issues in some dogs.
- Multiple protein sources mean it may not be ideal for dogs needing a true limited-ingredient or single-protein diet.
- Dogs with fish or pork allergies will need to avoid this formula due to the mixed animal proteins.

Top 5 Ingredients Explained
01
Bison
Bison is used as a high-quality animal protein in dog and cat foods, commonly included in limited-ingredient or novel-protein formulas for pets with food sensitivities. It supplies essential amino acids, iron and B vitamins and is typically leaner than beef—making it a lower-fat option that may require added fat or formulation adjustments for energy needs; as with all meats it should be part of a complete, balanced diet (especially for cats who need adequate taurine), be sourced and processed safely, and may still cause allergic reactions in some individual pets.
02
Whitefish
Whitefish (such as pollock, cod, or haddock) is commonly used in pet foods as a lean animal protein source that provides high‑quality essential amino acids, good digestibility, and some omega‑3 fatty acids to support skin, coat and muscle maintenance. While generally palatable and useful for weight‑managed formulas, pet parents should be aware of potential fish allergies and the importance of responsible sourcing and processing to minimize contaminants; cats also require adequate dietary taurine, so whitefish should be part of a complete, balanced diet.

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
Pork
Pork is used in pet foods primarily as a high-quality animal protein and flavor enhancer, supplying essential amino acids, B vitamins (especially B12 and niacin), iron and zinc, plus fat for calorie-dense energy; it can be suitable for both dogs and cats when balanced in a complete diet. Because pork can be relatively high in fat, it may be inappropriate for pets requiring low‑fat diets or those prone to pancreatitis, some animals may have sensitivities to pork, and raw or undercooked pork can carry parasites or pathogens so it should be properly processed or cooked.
