10 Best Dog Weight Gainers 2025 in the United States

Bully Max Dry Dog Food is a specialized product designed to support muscle and weight gain in dogs. One of its standout features is its high caloric content, providing 535 calories per cup, which is beneficial for dogs needing extra energy and weight gain. This high density also means smaller serving sizes, making it cost-effective in the long run. The protein content is substantial at 30%, predominantly sourced from chicken meal, which supports muscle development effectively. Additionally, the fat content stands at 20%, contributing to overall weight gain and energy levels.

The formulation includes quality ingredients like chicken fat, brown rice, and whitefish meal, which are known for their digestibility and nutritional value. The inclusion of dried plain beet pulp adds fiber, aiding in digestive health. Flavor-wise, the chicken blend is likely to be appealing to most dogs, enhancing palatability. However, the product's pellet form might not be suitable for very picky eaters or those with dental issues. The nutrient-rich composition includes essential vitamins and minerals, contributing to overall health and vitality across all life stages and breeds.

Notably, Bully Max adheres to high safety standards and has a strong reputation with no recalls reported. This makes it a reliable choice for dog owners seeking a high-performance diet. On the downside, the 5-pound bag size might be insufficient for owners of larger dogs or multiple pets, requiring frequent purchases. Additionally, while the high protein and fat content is beneficial for active and growing dogs, it may not be suitable for less active or overweight dogs. Bully Max Dry Dog Food is an excellent option for those seeking to enhance their dog’s muscle mass and weight in a healthy manner, though consideration should be given to the dog’s specific activity level and dietary needs.

The All American Canine Dog Weight Gainer is designed to help dogs gain weight quickly and healthily. It comes as a powder supplement, which is convenient to mix with your dog's regular food. One of its strengths is its rich blend of high-quality ingredients like beef broth protein, whey protein, flaxseed, and various powders from liver, sweet potato, and pumpkin. These provide a good balance of protein and fats, essential for building muscle and increasing energy.

It also includes probiotics and vitamins to support digestion, joint health, and overall well-being, which is a thoughtful bonus for dogs recovering or needing extra care. The flavor is duck liver and dressing, which many dogs find appealing, making it easier to encourage picky eaters. Importantly, the formula avoids artificial additives, trans fats, and unsafe substances, focusing on natural, safe components. The product does not specify exact calorie or macronutrient numbers on the label, so estimating precise intake might require some trial and error. Additionally, dogs with specific allergies or sensitivities to items like whey or liver should check with their vet before use.

The size is good for regular dosing with 60 servings per container, which should last well for most dogs. This supplement is well suited for dog owners seeking a natural, nutrient-rich option to help their dogs gain weight, especially when combined with a balanced diet. It may be less suitable if you want very precise nutritional tracking or if your dog has known allergies to the included proteins.

Bully Max 11-in-1 Muscle Gain Power Chews are designed for dogs needing extra muscle growth and recovery support. These chews are high in protein and calories, providing 5x more protein and 4x more calories per serving than many competing products. This makes them a potent option for enhancing muscle development in dogs of all breeds and all life stages, including puppies and adult dogs.

The inclusion of BCAAs like L-Leucine, L-Isoleucine, and L-Valine aids in muscle recovery and strength, which is beneficial for active or working dogs. Furthermore, the chews feature advanced antioxidant protection with astaxanthin, which supports overall health and immune function. The advanced time-release technology ensures optimal nutrient absorption throughout the day, enhancing their effectiveness.

These chews are also vet-recommended and safe for pregnant or nursing dogs. On the downside, the high caloric and protein content may not be suitable for dogs with specific dietary restrictions or those prone to obesity. Additionally, while the chews are designed to be tasty, individual dogs’ flavor preferences can vary. Finally, the chews require daily administration, which might be cumbersome for some pet owners. Bully Max chews are a high-quality option for supporting muscle growth and health in dogs, especially those involved in high physical activities.
