Grain-Free Cage-Free Chicken & Sweet Potato Formula Dry Dog Food
Verified Jun 14, 2026
This is a grain-free dry dog food that uses chicken and chicken meal as its primary protein sources, with sweet potatoes, peas, and lentils providing most of the carbohydrates. It’s formulated for all life stages, including large-breed puppies, and includes added omega fatty acids, probiotics, and taurine to support digestion, skin and coat, and overall health. The moderate protein and fat levels make it suitable for many normally active dogs, as long as grain-free and legume-based diets are appropriate for them.
Nutritionally, this is a solid, mid–higher protein grain-free option that can work for many dogs, including large-breed puppies, since it meets AAFCO standards for all life stages including large-breed growth. It offers animal-based protein, added taurine, and probiotics, which are all nice features. The main nutritional drawback is that peas and lentils are prominent ingredients, so I would be a bit cautious using this as the sole long-term diet in breeds already at higher risk for heart disease.

KibbleLab Review
Strengths
- Chicken and chicken meal provide good-quality animal protein as the first ingredients.
- Formulated to AAFCO standards for all life stages, including large-breed puppies, which is an important safety check.
- Includes added omega-3 and omega-6 fatty acids from flaxseed and salmon oil for skin and coat support.
- Contains probiotics and chicory root, which may help maintain a healthy digestive tract.
Considerations
- Peas and lentils are high in the ingredient list; legume-heavy grain-free diets have been linked to heart issues in some dogs.
- Chicken is a very common allergen, so this food would not be ideal for dogs with chicken sensitivities.
- Grain-free is not necessary for most dogs and removes nutritious grains that many dogs do well on.

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
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.
