So I have this dog, he's about 4 years old. He was a rescue, but he was obviously somones pet because he knew sit on command, and he was potty trained. He's the best dog we've ever had, he's ALWAYS went to the door when he's gotta 'go' and he used to get to the point where he would bark at us to let him out. Just recently he started running off, like across the woods by a neighborhood with my lab and theres a HUGE pack of dogs over that way, so I havent been letting him outside offleash and he's been going to the bathroom in the floor. He doesn't even go by the door anymore to let us know. What would make him do that? I take him out when I take my border collie out (about every 2 hours or so) if I let him of leash he'll run off. Now my parents are getting a little bit frusterated with me because I wont let him go, but I don't want him to get shot, eaten (hes a small-ish dog) or run over. am I making a mistake by not letting him go? And what would ya'll do about it?
