Thank you everyone
I will try through this winter to use the ideas you have posed. I really want to make this work out. We have another meeting with my son's psychologist next week and I will bring up the subject with her.
Yes, he is from a reputable breeder, but unfortunately since we got him, he has passed away, and his wife (co-breeder) has terrible Lupus. She will not be able to take him back in, but I'm sure she will know who would be willing to take him. He's an amazing dog with a wonderful temperament which is actually not typical of adult Shibas.
