Hi- I have an ongoing problem with my bulldog's urine making my backyard smell horrible. After years of his urine killing my lawn, this year I have him going in one spot of mulched yard. While this has been great for my grass, having it all concentrated in one area has made the smell worse than ever! Any tips on how to eliminate the odor? I see some expensive sprays (Dawgon, Odorzout) that claim to eliminate odors and if they work I'm willing to spend the money, but I'm afraid to try them without being sure. Also, does anyone know if those treats/sprays you can feed your dog to reduce odors/lawn burn are safe? Thanks for any advice!

Laurie
