This is a really difficult situation. My brother (who has a wife and three children) has bought the house next door to me and is currently renovating it (has been for the last year actually). They are not living there yet, they are living in a rented house five minutes down the road. About a year ago they bought a dog, a Blue Heeler cross Kelpie. It is currently living on a chain at the reno house. They havent bothered to train her so she jumps up all over you, doesnt sit or stay, doesnt come when called, doesnt heel when you walk her on a lead, and is basically the dictionary definition of unruly. She jumps the fences and gets in with my goats, where she just chases and chases and basically I have to chase her down and catch her because she doesnt come when you call her. They dont spend any time with her and she is stuck at a house by herself with no human contact, which is why she amuses herself by chasing my goats (she manages to get off her chain quite often, I'm not sure how). So if that wasnt enough, about three months ago they got three - yes three - mini jack russel pups. One for each of their kids, see. They are currently in a pen at the reno house too, because the rented house doesnt allow dogs. There three are already managing to get out of their pen, in fact one of my nephews said yeah I taught that pup how to climb up and out of the pen. A number of times now we have found them in my paddocks, chasing the goats (just because they are little doesnt mean the goats arent scared of them, plus they fit through my fences) and we have put them back, told my brother they are getting out and yet he doesnt do anything to modify the pen. And on top of it all, all four dogs are beginning to show aggression. The pups have on more than one occassion growled and run at me and tried to bite and my sister in law said they have done the same to the kids, and they often fight badly amongst themselves. The other night the heeler had knocked over her water and I went over there to see why she was yapping so much, I filled her bowl up and as I was leaving she nipped my hand. Honestly, I just dont know what to do. They werent looking after the first dog properly, now they have four that are being neglected, and they are posing a danger to my goats as well as people. Personally I believe any biting dog should be put down, but they dont see it that way. If it was anyone else I would simply catch the dogs once they were on my property and call the pound. But it is my brother which makes it a whole lot more complicated. I'm worried that someone (goat or person) is going to get hurt. I hate the way I'm thinking but I almost think it would be good if they tore into one of my goats, that way I would have a legal, legitimate reason to call the police and have the dogs taken away.
