Strong Choice
This food offers a relatively high protein level for an adult maintenance diet, with multiple named meats and meat meals leading the ingredient list. It’s a grain-free, legume-heavy formula, so it may suit dogs who truly need to avoid grains, but it’s not automatically better than grain-containing options. It’s best suited for healthy adult dogs who tolerate lamb and pork and don’t have issues with higher-calorie kibbles.

KibbleLab Review
Strengths
- Multiple named meats and meat meals provide rich animal protein sources for adult dogs.
- The 35% minimum protein and 14% minimum fat support active adult dogs with higher energy needs.
- Flaxseed and sunflower oil provide omega fatty acids that can support skin and coat health.
- Formulated to meet AAFCO nutrient profiles for adult maintenance, so it is complete and balanced.
Considerations
- This diet is grain-free and uses peas, chickpeas, and lentils heavily, which have been linked to diet-associated heart issues in some dogs.
- Lamb and pork are included, so it will not be suitable for dogs with known allergies to these proteins.
- At about 400+ calories per cup, it is quite calorie-dense and may require careful portion control for less active dogs.

Top 5 Ingredients Explained
01
Lamb
Lamb is commonly used in dog and cat foods as a high-quality animal protein that supplies essential amino acids, iron and B vitamins and is often chosen for its palatability or as a “novel” protein in elimination diets. It can be higher in fat and calories than some other meats and may still cause allergic reactions in sensitive animals, so owners of overweight pets or those with food sensitivities should consult a veterinarian and use proper handling/cooking practices if feeding raw or homemade lamb.

03
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.

05
Pea Protein
Pea protein is a concentrated plant-based protein and functional ingredient in pet foods used to raise protein levels, improve texture and contribute soluble fiber, vitamins and minerals. It can be a useful, digestible protein source for dogs and a supplemental protein in some cat formulas, but because it is lower in certain essential amino acids (and cats are obligate carnivores), diets relying heavily on pea protein should be formulated to meet AAFCO nutrient profiles and owners should note potential legume sensitivities and the debated link between high‑pulse, grain‑free diets and canine heart concerns.
