Strengths
- Turkey and turkey meal provide named animal protein sources at the top of the ingredient list.
- Formulated to meet AAFCO nutrient profiles for all life stages, including large-breed puppy growth.
- Includes added taurine, L-carnitine, and omega-3 and -6 fatty acids to support heart, muscle, skin, and coat health.
- Contains prebiotic fiber and multiple probiotic strains that can help support digestive health.
Considerations
- Peas and potatoes are major carbohydrate sources in this grain-free diet, which is a pattern linked in some studies to heart issues in certain dogs.
- Salmon oil and fish-derived omega-3s may be a concern for dogs with fish allergies.
- Protein at 24% is adequate but not especially high for very active or working dogs that may need more.
- Grain-free diets are not necessary for most dogs and may not be ideal for pets without a clear medical reason to avoid grains.

Top 5 Ingredients Explained
01
Turkey
Turkey is commonly used as a primary animal protein in dog and cat foods, offering highly digestible, high‑quality protein and supplying essential amino acids along with B vitamins, phosphorus and zinc to support muscle maintenance and metabolism. Its fat level varies by cut so products can be lean or richer; some pets may develop allergies to poultry, cooked bones are hazardous, raw meat carries bacterial risk, and owners should rely on balanced commercial formulations (and ensure adequate taurine for cats) if turkey is a main ingredient.

03
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.

04
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.

05
Pea
Pea is a plant-based ingredient used in pet foods as a source of protein, soluble and insoluble fiber, and micronutrients (often included as whole peas, pea flour, or pea protein concentrate) to boost protein content and improve texture. While peas can provide digestible carbohydrates, fiber, and some plant protein useful especially for dogs, they are not a complete protein for obligate carnivores like cats and — when overused, particularly in concentrated forms or as a major component of grain‑free diets — have been scrutinized for a possible association with canine dilated cardiomyopathy and can contribute to nutrient imbalances or excess calories, so balanced formulation and compliance with AAFCO nutritional profiles are important.
