Well, there are an awful lot of questions about your post:
1. Why are you posting, and not your X, as it seems that your X would be the one that would need to figure out what to do with the dog if it is his dog. I think anyone that agrees to help in any phase of rehoming the dog would need to get the information from the dog's owner as to the behavior/problems, etc.
2. When you say that the dog is an amazing dog, can you elaborate on that?
3. What time and attention does the dog need and how is he displaying that he needs it?
4. How old is the dog? Do you have pictures?
