Senior Medium Breed Dry Dog Food
Verified Jun 20, 2026
This is a dry kibble formulated specifically for senior medium-breed dogs, using chicken and chicken by-product meal as the main protein sources. It provides moderate protein and fat levels suitable for older, still-active dogs, along with added glucosamine, chondroitin, and fish oil. Antioxidants like vitamin E and beta-carotene, plus prebiotic fibers, are included to support immune, joint, and digestive health in aging dogs.
Nutritionally, this is a well-balanced senior formula for medium-breed dogs over about 7 years old who remain reasonably active. It offers good-quality, animal-based protein, joint-supporting nutrients, and a sensible calorie density for seniors. It should suit many older dogs without specific medical issues, especially those that do well on chicken- and grain-based diets.

At a Glance
KibbleLab Review
Strengths
- Chicken and chicken by-product meal provide good-quality, highly digestible animal protein as the primary protein sources.
- Protein (27%) and fat (12%) levels are appropriate for many senior, medium-breed dogs who still have a moderate to high activity level.
- Includes glucosamine and chondroitin sulfate, which can help support joint health in aging dogs, plus added DHA and fish oil for brain and skin/coat support.
- Contains prebiotic fiber (beet pulp, fructooligosaccharides) and antioxidants (vitamin E, beta-carotene) to support digestive and immune health, and is formulated as a complete and balanced diet for senior dogs in the stated weight range.
Considerations
- Chicken and egg are common food allergens, so this formula would not be appropriate for dogs with known sensitivities to these ingredients.
- Grains like wheat and corn are prominent carbohydrate sources; while nutritious for most dogs, they may not suit individuals with specific grain allergies (which are less common but do occur).
- Calorie density is fairly high at about 330 kcal per cup, so portion control is important for seniors prone to weight gain or with lower activity levels.

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.
02
Chicken By-Product
Chicken by-product is a common protein ingredient in pet foods made from edible parts of the bird not typically consumed by people—such as organs (liver, heart), necks and other tissues—and is used to add protein, flavor and nutrient density. It can provide concentrated protein, essential amino acids, B vitamins and minerals (and may contribute taurine when organ meats are included), but composition and quality vary by source, so pet parents concerned about sourcing, higher ash/fat content or chicken allergies should check the manufacturer’s labeling and quality standards.
03
Wheat
Wheat is a common cereal grain used in pet foods as a source of digestible carbohydrates, some plant-based protein, B vitamins, minerals, and dietary fiber, and it also helps with kibble texture and binding. It provides energy and fiber for many dogs but can cause food allergies or gluten sensitivities in a minority of pets and is generally less ideal as a primary ingredient for obligate carnivores like cats, so pets with known grain or wheat sensitivities should avoid it and calorie intake should be monitored to prevent weight gain.
04
Corn
Corn is commonly used in dog and cat foods as a digestible source of carbohydrates and calories, and it also provides some plant protein, fiber, B vitamins and minerals while helping with kibble structure and palatability. While generally safe and economical, corn is relatively high in starch and has an incomplete amino acid profile for obligate carnivores (cats), can be a source of mycotoxin contamination if poorly stored, and although true corn allergies are uncommon, some pets may be sensitive, so quality and proper formulation with animal proteins are important.
05
Chicken Fat
Chicken fat is used in dog and cat foods as a concentrated energy and flavor source that supplies essential fatty acids (notably linoleic acid) and aids absorption of fat‑soluble vitamins, improving palatability and supporting skin and coat health. Because it is calorie‑dense, diets must account for added fat to prevent weight gain, and quality (proper rendering and antioxidant protection to prevent rancidity) is important; although fats are less commonly allergenic than proteins, pets with poultry sensitivities may still react in some cases.
