Daisy's urine is ruining the lawn at our new house. I've heard of a supplement called "green ums" which contains amino acids & b vitamins among other things that break down the nitrogen in the urine/feces. Have you heard of this? If so, should it work? Are the ingredients safe for long term? I've also heard of something called a "pee post", which is a stake treated with pheremones that you put into the ground where you want your dog to "go". What's your opinion on these things? Help!!
