Medalseries High-Protein Senior Chicken & Lentils Recipe Dry Dog Food
Verified Jun 11, 2026
This is a grain-free, high-protein dry food formulated for senior dogs, with deboned chicken, turkey meal, and fish meal as the primary protein sources. Peas, lentils, and sweet potato provide carbohydrates and fiber, while added glucosamine, chondroitin, and L-carnitine support joint comfort and healthy weight in older, less active dogs. It also includes omega fatty acids and probiotics to support skin, coat, and digestive health.
This senior formula offers a strong protein level for an older-dog diet, with multiple animal protein sources and a moderate fat content that can work well for many aging dogs. It includes joint-support nutrients, omega fatty acids, and probiotics, which are all nice extras for seniors. It should suit most adult and senior dogs who don’t have issues with chicken or legumes and are at a normal or slightly heavy body condition.

KibbleLab Review
Strengths
- Animal proteins like deboned chicken, turkey meal, fish meal, and trout are all high on the ingredient list, giving seniors good-quality protein.
- Protein and fat levels are appropriate for many older dogs, supporting muscle while avoiding an overly rich formula.
- Includes glucosamine and chondroitin, which can help support joint health in aging dogs.
- Contains probiotics, salmon oil, and fruits and veggies that contribute to digestive and overall wellness.
Considerations
- Chicken and turkey are common triggers for food allergies, so this is not ideal for dogs sensitive to poultry.
- Peas and lentils are prominent ingredients; for breeds at higher risk of heart disease, discuss legume-heavy diets with your vet.
- Dogs needing very low-calorie or kidney-support diets may require a more specialized senior or prescription food.

Top 5 Ingredients Explained
01
Deboned Chicken
Deboned chicken is a common primary animal protein in pet foods, providing highly digestible essential amino acids and nutrients such as B vitamins and iron that support muscle maintenance, growth, and overall health in both dogs and cats. It is generally palatable and relatively lean, but can be a common food allergen for some animals and its nutritional and fat content varies with inclusion of skin or fat—ensure proper sourcing and handling to reduce contamination risk and consult a veterinarian if you suspect a food sensitivity.
02
Turkey
Turkey is commonly used as a primary animal protein in dog and cat foods, offering highly digestible, high‑quality protein and supplying essential amino acids along with B vitamins, phosphorus and zinc to support muscle maintenance and metabolism. Its fat level varies by cut so products can be lean or richer; some pets may develop allergies to poultry, cooked bones are hazardous, raw meat carries bacterial risk, and owners should rely on balanced commercial formulations (and ensure adequate taurine for cats) if turkey is a main ingredient.
03
Menhaden Fish
Menhaden fish is used in pet foods primarily as a high-quality animal protein and as a concentrated source of fish oil rich in omega‑3 fatty acids (EPA and DHA), which support healthy skin and coat, joint mobility, and anti‑inflammatory benefits for dogs and cats. It enhances palatability and provides essential micronutrients like iodine and selenium, but owners should be aware of possible fish allergies, caloric density and oil oxidation, and prefer products from reputable, sustainably sourced suppliers to reduce contamination risks.
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
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.
