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 2-in-1 Muscle Builder Power Tabs are chewable tablets designed to support muscle gain and comprehensive health for dogs of all ages and breeds. This product excels in offering a blend of muscle-building and multivitamin benefits, with nine key ingredients to promote muscle growth. Additionally, it includes essential vitamins and minerals for health support, including heart health, joint support, and cognitive function.

The tablets come with a blend of natural ingredients, ensuring a safe and potent formula without harmful additives. They are flavored to be appealing to dogs, making them easy to administer daily, which is a significant advantage for pet owners.

While the product is made in the USA with globally sourced ingredients, some pet owners might prefer locally-sourced ingredients only. These tablets are a good choice for dogs needing support in weight management, muscle development, or overall vitality, and they come highly recommended by veterinarians.
