Built for dogs who need to thrive, not just survive. Whether you're rebuilding an underweight rescue, fueling a working dog, or helping a senior keep their topline — Petterm Muscle Gain Soft Chews deliver real protein in a flavor your dog will actually want.

Lean muscle, the right way

Each chew packs 800 mg of Whey Protein Concentrate plus 200 mg of vegetable fat — the same building blocks athletes use, scaled for canine biology. No empty calories, no synthetic fillers.

Faster recovery, longer stamina

A targeted blend of L-Arginine, L-Lysine, Leucine, Isoleucine, and L-Histidine helps active and senior dogs bounce back from exertion and hold mobility as they age.

Skin and coat support built in

180 mg of Omega-3 fatty acids and 15 mg of zinc in every serving keep skin supple and coats glossy — visible results in 4–6 weeks.

Daily vitality bonus

Vitamin D3 and B12 fuel energy metabolism and bone strength; MSM, pumpkin seed, and brewer's yeast round out a complete nutritional foundation.

Salmon flavor dogs love

Soft, palatable chews made with natural salmon flavor, flaxseed, and rosemary extract. No struggle, no pill-hiding — just hand it over and watch it disappear.
