Also I feel I must note that my back yard is fenced in with a 6foot high wooden security fence. No neighbor should ever step where my dogs poo. Even if I don't clean it out but once a week it's still not accessible unless, and we've had a couple of idiots do it, you jump our fence.
I have big dogs, my male dog is almost 100 lbs and while he is a perfect sweetie sometimes my neighbors do things like hit/throw a ball into my yard and then think it's a good idea to try to climb my already dangerously high fence and get it from my dogs. I've had to ask people to not do that a few times. That's probably my biggest pet peeve regarding animals. My dogs are large and because of that I had a lot of flak when I got home owner's insurance. They basically told me that if my dog ever bit anyone, even if it was in defense of itself or me, I would lose my insurance unless he was put down and we've had neighbors do stuff like throw garbage at him, throw sticks at him. One time, a few weeks after my girly dog had puppies my idiot neighbor tried to go over the fence and pick one up to show his daughter. I noticed and asked him not to then I picked one up and showed her, Duke didn't give a shit, but about a week later when the neighbor was over with her, he let me handle them, let the little 7 year old girl handle them, but the moment the guy tried to go near them he went all pissed off. So, I was like, "Just think what would have happened if I hadn't been here and you had jumped the fence last week. Getting over it is hard when you're trying to climb over unhindered, but with Duke trying to tear off your ass I think you'd have had a hard time." He was like, "Oh jeez, I didn't even THINK OF THAT."
