Adult Dog Lamb Meal & Rice Formula Dry Dog Food
Verified Jun 15, 2026
This is a dry kibble formulated for adult dogs, using lamb meal as the primary animal protein along with rice and other grains for energy and fiber. It includes added omega-3 and omega-6 fatty acids for skin and coat support, plus a blend of probiotics and fiber sources aimed at supporting healthy digestion. Superfood ingredients like kale, chia seed, pumpkin, and blueberries contribute additional vitamins, minerals, and antioxidants.
Overall, this is a solid, well-rounded adult dry food that should suit many healthy adult dogs. It offers moderate protein and fat levels, lamb meal as the main animal protein, and a mix of rice and other grains for digestible carbohydrates. The added probiotics, taurine, L-carnitine, and omega fatty acids are nice extras for digestive and general wellness support, as long as they fit your dog’s individual needs and any food sensitivities.

At a Glance
KibbleLab Review
Strengths
- Lamb meal is a named, concentrated animal protein source, providing good quality protein for adult maintenance.
- Uses rice, barley, sorghum, and oatmeal as primary carbohydrates, which are generally well tolerated and provide fiber and nutrients rather than empty calories.
- Includes added omega-6 and omega-3 fatty acids, which can help support skin and coat health in many dogs.
- Fortified with probiotics, prebiotic fibers, and a variety of “superfood” ingredients (like kale, pumpkin, chia, and blueberries) that contribute additional micronutrients and antioxidants.
Considerations
- Contains egg product and chicken fat, so it is not suitable for dogs with known chicken or egg allergies despite being lamb-based.
- Protein level is moderate rather than high; very active, working, or underweight dogs may need a higher-protein option or careful portion adjustments.
- Includes dried yeast, which is safe for most dogs but may not be ideal if your dog has had sensitivities to yeast-containing foods in the past.

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.
02
White Rice
White rice is a highly digestible carbohydrate commonly used in pet foods as an energy source, binder or filler and is often included in bland diets to help manage gastrointestinal upset. It supplies readily available calories but contains little protein, fat, fiber or micronutrients (so complete diets must be balanced), and should be used judiciously in overweight or diabetic pets due to its high glycemic index; prolonged exclusive feeding is not recommended.
03
Barley
Barley is a cereal grain used in pet foods primarily as a digestible carbohydrate and source of dietary fiber (including soluble beta‑glucans), along with modest amounts of B vitamins and minerals. It can support healthy digestion, help moderate post‑meal blood sugar and aid weight management in dogs, but provides limited protein for obligate carnivores like cats, must be cooked/processed for good digestibility, and may be unsuitable for pets with grain sensitivities or calorie‑restricted diets.
04
Grain Sorghum
Grain sorghum is a gluten-free cereal grain used in pet foods primarily as a carbohydrate and fiber source that also contributes modest plant protein, B vitamins, and minerals, often serving as an alternative to corn or wheat. It supplies energy and dietary fiber for dogs and cats but is relatively low in certain essential amino acids (like lysine), and some tannin-containing varieties can reduce palatability and nutrient digestibility—processing and balanced formulation mitigate these issues, and sourcing should guard against mycotoxin contamination.
05
Egg Product
Egg product is used in pet foods as a high-quality, highly digestible animal protein and palatability enhancer, providing complete essential amino acids, fats, vitamins (such as A, D and B12), minerals and choline, and it often serves as a binder or emulsifier when included as whole, dried or concentrated egg. It supplies bioavailable nutrients for dogs and cats but can be a food allergen for some individuals, may be higher in fat depending on yolk content, and should be properly processed (pasteurized or cooked) to reduce microbial risk.
