Strong Choice
This is a moderate-protein, grain-free kibble centered around fish-based proteins and legume carbohydrates, suitable for most healthy dogs at any life stage, including large-breed puppies. The added taurine, omega-3 and omega-6 fats, and probiotics are thoughtful inclusions for general wellness. Because it’s grain-free and relies heavily on peas and lentils, it’s best chosen with some extra discussion if you have a breed with known heart concerns.

Strengths
- Whitefish and fish meal as the first ingredients provide a clear, animal-based protein foundation.
- Formulated to meet AAFCO nutrient profiles for all life stages, including large-breed growth, so it can be used long term.
- Added taurine and omega-3 fatty acids from fish and flax support heart, skin, and coat health.
- Includes multiple probiotic strains and chicory root, which can help support a healthy gut microbiome.
Considerations
- This is a grain-free food that relies heavily on peas and lentils, which have been linked in some studies to heart issues in certain dogs.
- Fish is a common food allergen for some dogs, so this recipe would not suit fish-sensitive pets.
- At 24% protein, it is on the moderate side; very high-activity or working dogs may do better on a higher-protein formula.

Top 5 Ingredients Explained
01
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.
02
Fish
Fish is commonly used in pet foods as a highly digestible animal protein and an excellent source of omega‑3 fatty acids (EPA and DHA) that support skin and coat health, joint function, and cognitive development in both dogs and cats. It also supplies B vitamins and minerals but can be a common allergen, may contain environmental contaminants or mercury depending on species and sourcing, and raw fish can contain thiaminase—so choose properly processed, nutritionally balanced, and sustainably sourced fish ingredients.
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
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.

05
Lentil
Lentils are a plant-based source of protein, complex carbohydrates, fiber and micronutrients (notably folate and iron) commonly used in pet foods to add bulk, promote satiety and help moderate post-meal blood sugar. They can be a useful ingredient for dogs when properly processed and balanced with animal-derived amino acids, but lentil protein is less digestible and incomplete for obligate carnivores like cats; high legume inclusion can also increase gas or digestive upset and has been discussed in the context of diet-associated heart concerns in dogs, so lentils should be used in nutritionally complete, vetted formulations.
