Dog pee problem? Absoultely. We replaced our small front lawn with mulch, and mixed small shrubs and thyme and for some reason, the neighborhood dogs think it's their personal toilet area. It smells like a barnyard everytime I open the front door. I tried various spray repellants, mothball chips and finally resorted to small fencing. Nothing has worked. I actually caught a dog-owner with his pet doing his business there and asked him to go in front of his own house. The man replied that he can't help where he dog decides to stop and pee. What's up with that?? Anyway, are you concerned about your own dog or others? If it is your own, can you train it to go elsewhere??
