Strong Choice
This is a high-protein, grain-free dry food formulated for puppies of all sizes, including large breeds, and is also suitable for pregnant or nursing dogs. It features chicken-based protein, added DHA, and probiotics, which are all helpful for growing puppies. Because it relies heavily on peas and other legumes instead of grains, it does fall into the formulation pattern that has been associated with diet-related heart concerns in some dogs, so that’s something to weigh when choosing a long-term puppy diet.

Strengths
- Chicken and chicken meal provide concentrated, animal-based protein to support puppy growth.
- Formulated to meet AAFCO nutrient profiles for all life stages, including large-breed puppy growth.
- Includes added DHA from salmon oil, which is important for brain and eye development in puppies.
- Contains probiotics and prebiotic fiber to help support a healthy digestive tract.
Considerations
- Chicken and egg are common allergens, so this formula is not ideal for puppies with known sensitivities to these proteins.
- This is a grain-free diet that relies on peas, lentils, garbanzo beans, and fava beans as main carbs, a pattern linked to diet-associated DCM in some dogs.
- The calorie density is fairly high, so portions need to be measured carefully, especially for large-breed puppies to avoid overly rapid growth.

Top 5 Ingredients Explained
01
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.

03
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.

04
Chickpea
Chickpeas are a legume commonly used in pet foods as a plant-based protein, source of digestible carbohydrates, and supply of soluble and insoluble fiber that helps with stool quality and satiety. They can be a useful ingredient for dogs but are not a complete protein for obligate carnivores like cats and may cause gas or digestive upset if underprocessed; additionally, high inclusion of legumes in some grain‑free diets has been discussed as a potential factor in canine dilated cardiomyopathy so diets should be balanced and any concerns discussed with your veterinarian.

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.
