i agree with bb, he needs to take resposibility for that dog. not you. i lost a few chooks to a dog earlier this year. i collared the dog, dragged it up the road and told the owner in no uncertain terms that if it did it again id shoot it. i havent got a gun, but he doesnt know that. since then hes been nice as pie, bringing wood over for me, and we actually get on really well. maybe standing up to your neighbour may well earn his respect.
