Next door neighbor moved in almost 2 yrs ago. Our driveways are right next to each other so you kinda see more that you want to sometimes. They have a pretty big dog. We were told by the previous neighbors that they would be putting up a backyard fence as soon as they moved in. No big deal to us. We don't have a fence in the backyard and its pretty far down on my priority list. They never put up a fence. Everything was fine until about a month ago. I walk around the side of the house and there are piles of dog stuff in their backyard as well as mine. I thought maybe they didn't have time to pick it up and let it go. Today I go to mow the entire yard and once again, there are piles in my side yard and backyard. Whats a nice way to approach this. I don't want to cause WWIII but I don't want the stink in my yard either. Anyone?

Good luck!
