I also hate loose dogs as they pose problems for others.
We had a neighbour who used to send his dog over to poop on our lawn.. can you imagine .... Wayne finally got sick of it and went out our back yard picked up every poop he could find and a few more from the front and threw it over to the guys front lawn ,takes a lot to rile my man but he sure was mad that day

Another problem arises if big dogs are on the loose they can actually jump fences and harm another persons small dog
