I think Misty should be fine but i don't think there is anything you can do about the other dog.If youv'e already tried a very experienced trianer I'm sorry but I would have to say you should put him down.I just wantd to tell you the Petsmart trianers don't work for some diffrent types of dogs.It worked really well for my beagle and rotweiller but didn' work at all for my belovd but evil cockapoo.I'm really sorry for the oher cockapoo but there is probably nothing you can say or do to fix that dog.
