Well now I've got an issue along these lines, and it's kind of complicated ...
Our house shares a lane with two other households. The first house is along the main lane, so everyone has to pass it going in, then it forks and we're at the end of one fork and another house is at the end of the other.
So the house on the main lane has a dog. No big deal. She's wary of people, will bark at anyone who goes by, but generally well behaved.
Then other neighborhood dogs started showing up to play with the dog that's actually theirs. One of them chases cars. Kind of a PITA when you're trying to get somewhere in a hurry, but still not that huge of a deal. This dog was eventually abandoned by his owners who moved out, and now my neighbor feeds him. She tried to bring him into her house, but he isn't housebroken, and at probably 6-7 years old, he wasn't interested in learning and she wasn't interested in cleaning up after him.
Lately yet another older dog showed up at their house that no one knows where he came from. He was near-starving and had an infected eye and ear. Now he's got a pack to play with and shared bowls to eat and drink from and no interest in leaving, and soft touch that my neighbor is (I'd do the same, no criticism to her) she decided against taking him to the pound and accepted him into their outdoor "household" too, got his eye and ear taken care of, got them all their shots, etc.
But. The latest dog, when he first showed up all sick and weak, let me skritch his ears. But as he became integrated into the neighbor's "pack," he became as wary of me as the other two. I've tried to coax them to me many times as I pass their house when I run, but they're just not interested. Fine if they don't want to be my friends. But the latest dog has started chasing me the length of their property, like 1/4 mile of rough gravel, climbing up on my heels, and the other day he actually nipped me in the butt. Slightly broke the skin. That is NOT okay. And worse, now I'm a little scared to go by there, though I've passed him twice now without him trying to bite again.
I haven't seen my neighbors to speak to them since this happened. I'm not quite sure what to say. It's still not really "their" dog and they've never had much control over the two that aren't really theirs. They've got a young daughter who loves all the dogs. A couple of years ago our other neighbor shot another semi-feral dog that hung out there, after he says it started killing feral cats, and that was a major incident between the two families. Animal control doesn't even bother with country dogs, it's on us to either shoot the dog or deal with it, and I'm not going to shoot him no matter what. Anyone have any better suggestions???
