Put up a fence, may cost you some now but in the long run it will be worth it. GOOD FENCES MAKE GOOD NEIGHBORS, when we bough our house in Fla every one around us was family, and one of the family had sold to us. the first thing we did was put up a fence, my DH told all the neighbors that since we had 2 dogs we did not want our dogs on anyone else's property, even tho they were toy poodles, we wanted them to stay home. Every one respected that and we got along great for 16 years until we sold.
