About Stewart
Stewart Pet Products has manufactured freeze-dried single-ingredient dog treats in Dayton, Ohio since the 1970s, earning a reputation among professional dog trainers as the gold standard for high-value training rewards.
Heritage & History
Stewart Pet Products is based in Dayton, Ohio, where the company has produced freeze-dried animal protein treats for dogs for decades. The Pro-Treat line was developed to meet the exacting standards of professional dog trainers, who need a treat that is high-value enough to motivate dogs during demanding training sessions but pure enough not to cause digestive disruptions during long training days.
Freeze-drying was Stewart's method from the start. The process removes moisture from raw meat at low temperatures, concentrating flavor and protein while preserving the natural nutrients and enzymes that heat-based drying destroys. The result is a treat that smells intensely of fresh meat — which is exactly why professional trainers prefer it over baked or cooked alternatives. When a dog can smell a reward from across a training yard, that's a high-value treat.
Made in Dayton, Ohio
Stewart's Pro-Treat line is manufactured in Dayton, Ohio from 100% USA-sourced meats. The beef liver, chicken breast, pork liver, duck liver, and turkey lines all start with a single American-raised animal protein — no blends, no fillers, no binding agents. The freeze-drying facility in Ohio processes each protein to the same standard: pure single ingredient, no artificial preservatives, no salt, no additives of any kind.
Professional dog trainers have made Stewart Pro-Treat their go-to for a reason that's easy to understand: dogs work for what motivates them, and a pungent, single-ingredient freeze-dried liver treat from Ohio motivates most dogs better than anything from a bag of mass-market treats. The 2-oz tub is designed for training portability — small pieces break off easily, and the quantity is sufficient for a full training session without bulk. The larger 14-oz containers serve multi-dog households and professional trainers who go through treats quickly.
