10 Best Dog Weight Gainers 2025 in the United States

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.

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.

Under the Weather Pet's Ready Cal for Dogs is a gel-based high-calorie supplement designed to support dogs who need help gaining weight or getting proper nutrition. Its gel form makes it easy to administer, and the measured tubing helps ensure accurate dosing. The supplement is rich in calories and includes 10 essential vitamins, 7 minerals, and omega fatty acids, which contribute to health and nourishment.

This mix of nutrients benefits dogs recovering from illness, those with poor appetite, or underweight dogs of all breeds and life stages. The flavor is formulated for dogs, making it generally palatable. The ingredient quality appears solid, and the product is made in the USA, which can be reassuring.

As a gel supplement, it may work best as a temporary booster rather than a complete meal replacement. If your dog struggles with eating solid food or needs a quick calorie boost, this product could be helpful. Those seeking a more balanced macronutrient profile or specific protein levels might consider additional food or supplements.
