Dog urine and lawns don’t always mix well. The fundamental problem is that urine is a waste product containing excess nitrogen resulting from the natural metabolism of protein within the body. When dogs urinate on grass, urinary nitrogen mixes with the nitrogen already present in the soil and “burns” the grass. Nutri-Vet lawn protection supplements are formulated to reduce urinary nitrogen and help reduce grass burn and maintain a “spotless” lawn. Grass Guard max chewables with probiotics and digestive enzymes liver flavor chewables for dogs contain a unique blend of probiotics, digestive enzymes, amino acids and botanicals to help prevent lawn burn and yellow spots on grass. Veterinary formulated to help neutralize nitrogenous waste and maintain slightly acidic urine, Grass Guard Max is easy to give, extremely palatable and very effective in maintaining a "spotless" lawn.
