We got a pound dog a while ago. He has bad seperation anxienty. We got him a friend and that helped a bit but when he isn't with people he whines and cries and carries on whether he is outside, inside, or in teh crate. Any ideas on how to help him out with it? I have tried a kong with him filling it with hotdog chunks and peanut butter but its onle a matter of time before he has it empty then he is his whinny self.
