I am wondering too how old Ozzy is. We had a smooth coated collie in obedience school and he was a real handful, but by the end of 10 weeks of classes the improvement was amazing! The instructor stressed that it only takes 15 min. a day of working with your dog until they start to "get it." It sounds like you pretty much have your mind made up so I'm not going to ask you to reconsider. You know your own situation. Many times a breeder will want the dog returned to them. This is a good place to start in your efforts to re-home Ozzy and it sounds like you have already considered that. (((Hugs))) to you as you go through this. I have never had to do this and I know if I ever had to give up one of my dogs it would just kill me!
