A few months ago we got some new next door neighbors. They have a few small kids and a few weeks ago they had a party and the kids threw some stuff (balls and toys) into our yard. Kids will be kids right? Their parents apologized after they saw our dog, Tiger, popped the balls and chewed on the toys and said they would talk to their kids. A few nights ago I found 4 flattened balls, 2 water bottles, and a cup and threw them all away and talked to them (again). Last night there was another toy back there, all mashed and mangled up cause Tiger got to it again, I spoke to the father (again) and yet again, this afternoon I find another cup thrown over. I spoke with the father (again). I've about had it and don't know what to do. Obviously talking isn't working. Does anyone have any suggestions?
