I have two dogs in this fight, and I must say, their pee does indeed kill the grass. First it turns yellow, then it dies, then weeks later it grows back. It could be the fact that they are big dogs, or it may be the breed (a former one killed the grass too). In our neighborhood the people with big dogs don't let them pee on other people's yards. I don't get bent out of shape--the little dogs don't seem to harm our lawn.

One of our dogs is trained to pee in the landscaping stones (doesn't kill the bushes). The other one is too rickety to balance on that and so is systematically beating the heck out of one part of the backyard. A small price to pay for having this old guy.
