Some dogs simply burn more calories than they can replace through regular feeding. Pennwoods Body Builder 4000 is a high-calorie, high-protein supplement designed for hard keepers, working dogs, hunting dogs, and highly active or high-metabolism dogs. With 40% fat and 26% protein, it delivers maximum calorie density to support healthy weight, muscle maintenance, endurance, and sustained energy without increasing meal volume.

Formulated with a complete amino acid profile, Body Builder 4000 helps maintain lean muscle, aid recovery, and support performance during periods of heavy activity, training, or work. Highly palatable and easy to top-dress, this practical, small-batch formula fits seamlessly into your dogs feeding routine.

Pennwoods, producing performance nutrition for horses since 1985, has developed Body Builder 4000 as a new line for dogs, bringing their decades of expertise in results-driven, performance-focused formulas to canine companions. Maximum Calories. Minimal Volume. Built for Dogs That Work.
