I know that I have to spray my yard and clean with this mixture, but will my grass die off forever? I called a local nursery and they said nothing will ever grow back, the lawn care companys I called said it will eventually return. I'm confused. And what are any other tips for cleaning after he gets better? He has already been taken to the vet and is on medication and seems better already. As environmentally unfriendly as it may sound, all websites have said to clean with a 3:1 ratio of bleach water. It's better to kill the grass as opposed to infecting other dogs. I rent my home, so I don't want to have a professional come in to replace lawn. I'd rather put the work in myself than to pay and arm & a leg for someone else to do it.
