No, seriously, you're not giving us anything to work with here. We don't know you or how much you know about the game, and we can't look at your world, so you have to tell us how you got your dog and what happened before it stopped behaving the way you expect. Otherwise I'll have to ask you a million questions, like "Did you tame this dog yourself? How long have you had it? Has it ever sat for you before?" and so on. That would take us a long time to get to the problem. It'll go a lot faster if you try to give us all that kind of information up front.
