What can I use to neutralise the smell of dog pee in my garden without killing my lawn. I hose down a couple of times a day but it's. It enough in this heat and it's getting whiffy. I just keep the back doors open when it's nice so don't catch him every time To hose as I go. If I didn't want to protect the plants I'd zoflora/bleach and dilute in a watering can. What do you think? Tips welcome.
