PetiGreenI have a Bichon Frise who is just adorable, but the lawn spots he leaves are not! I purchased Pet-I-Green and applied it every six weeks during the Spring and Summer, and my lawn was green and beautiful by October. Currently is covered with snow, but I'll be back applying Pet-I-Green in the Spring. I just put into my hose sprayer and let it fill with water and then covered my lawn. It is very easy to use.
