Thats what I worry about too how easy it is for someone to throw something bad over your fence to them. We have had someone leave poisoned meat in parks frequented by dog walkers and there were a couple dogs who died from it { assumed was offleash dogs owners didnt see} but numerous sick dogs from that. As well as another case last year someone was leaving out bowls of anti freeze in the forests , alot of sick people. I always walk my yard to check things out but who is to say if someone hates this breed so much they dont start poisoning them in there own yards. Need to be careful .That's scary, I don't keep my dogs outside because of idiots throwing cooked bones over the fence, toys that could easily be choked on, etc. Even caught people sticking fishing poles through the fence. And a dog murderer? Hopefully people are taking their dogs inside in that area.
