Oh, that's hard, Jello, when pets aren't cared for and allowed to run "wild". I'm surrounded by dogs (have 2 cats) and we don't have fences really, just little not even waist-high things or split rails. The one dog, Amber, on my left always jumps the waist-high and heads over to the other yard on my right :-) to poo there where there's grass (her owner's more or less bricked the tiny townhouse backyard and they have 3 dogs they let out there!) and then she wanders around front and I guess goes in their front door. Sometimes though she goes in our yard. I don't say anything since it's neighbors and doesn't happen often, etc. I hate the do-I-get-along or do-I-kill-the-neighbors delimma. But were townhouses and on the water so everyone is out there all summer, would make it ugly to not get along. And our neighbors help us as we're newbies, old, and clueless about our boat, etc.
