Dog urine is a concentrated solution of ammonia AND salts. It overwhelms grasses and soils, creating a "dog spot" or "dog hot spot" where grass no longer grows.
Guard Dog™ attacks the problem in three ways:
consumes the ammonia
binds the salts
increases soil permeability
This unique, multiple-action formula provides homeowners with consistent performance.
