Muscle+ Protein Powder Helps Your Dog

This powerful mix of all-natural, active ingredients delivers 5 key benefits.



Muscle Mass and Power

ProDog Muscle + is loaded with ProDog’s revolutionary tri-protein blend of hemp, pea & kelp protein, delivering a world first 76% natural protein per serving; ensuring the full amino acid spectrum needed to attain optimum physical condition is delivered in abundance. This plant-based protein combination supports energy levels, aids lean muscle and weight gain to give long-lasting strength and definition, whilst also being kind to a dog’s digestion.




Muscle+ aids repair of fibres broken down within the dog’s muscle after work or training, supporting larger and stronger rebuild and delivering long term gains. 




This cutting edge formula supports fitness, strength and health by replenishing vital vitamins and minerals naturally depleted through active lifestyle. Our signature, tri-protein blend delivers the amino acids required for muscle gain and long-lasting definition, whilst also supporting regulation of the glandular system, heart health, healthy cholesterol and blood pressure levels and simultaneously working to nourish the nervous system.




Formulated using 100% species-specific ingredients. ProDog triple protein blend is a plant-based protein that is kinder to a dog’s digestive system than milk-based proteins – such as whey – that are often found in canine supplements. In addition the glucosamine component makes this all-natural blend highly nourishing to a dog’s digestive system whilst supporting effective nutrient absorption.


How it helps your dog



Increasing muscle mass requires a strong supporting structure and optimal foundational functions. The fish collagen and oil component of this formula makes it a plentiful source of Omega 3, 6 & 9 fatty acids, essential nutrients to support brain and gut function, aid joint mobility and flexible cartilage. Hugely supportive of the immune system, omega oils work to help maintain a balanced natural inflammatory response, assist detoxification, help to neutralise free radicals and aid regulation of the body’s natural energy mechanisms.


Who isProDog Muscle+ for

ProDog Muscle + is extremely beneficial to ALL dogs who require muscle bulking or safe weight gain. The powerhouse fusion of natural ingredients are all specifically selected to support increased muscle mass and aid optimisation of strength, speed and stamina, regardless of size or breed. Rigorous testing and customer feedback have proven Muscle + to be a highly effective formula, delivering outstanding results.
