Guy I used to work with lived in town. Not a dog/pet owner, 3 different houses around him had big dogs and all used his lawn to crap on. Dogs ran free most of the time. He tried to talk to the owners but got no where. He went and bought a paint ball gun and pink paint balls and started doing some art work on the dogs in his yard. 2 of the neighbors got the message and built dog runs out in their back yard for their dogs. The other one was a big jerk, came over and cussed the artist out, and while there, his dog was craping right in front of the owner. There was no more communication with that guy. The artist went down to the local greasy spoon café and got a big can of bacon and burger grease, warmed it up till liquid and then ladeled the warm bacon grease on every dog pile in his yard. Jerks dog made a bee line for it and ate every pile of his own bacon flavored dog *****. Sort of like cleaned up his own crap in the yard. Well after all that bacon grease the dog had to have water assap, so it ran home and gorged itself on his water bowl, well all that water hit that bacon grease soaked dog dirt and guess what happened, dog voided everything in him on the owners carpet, Sort of made a relocated redeposit. The guy that owned him took him to the vet to get checked, lost a day of work and spent CASH at the vets office. Not to mention the carpet cleaning bill. Vet told the owner his dog got into some garbage and ate something rancid and he should not let his dog run loose. Some people you just cant deal with by talk, but at least he tried.
