I had a pasture that bordered a subdivision and would constantly get there leaves, limbs, dead flowers, dead shrubs, rocks, and everything else across the fence. It all would get tossed back over and I would try my best to hang it up in their tree limbs so they would get the message. One house started throwing their dog crap across the fence, and I mean big loads of it. I just figured if it was OK to pitch poo one way it would bee OK to pitch poo the other way, except I did not have a dog so I just had to pitch cow pies. After about an hour my arms were getting tired and their pretty backyard was well fertilized anyway. Message received!
Country life don't mean you get to let your dog run loose.
