Yes golden, and while some posters suggest she just up and end her relationship, I would rather suggest ways she can work around this challenge and even look at it differently. A dog doesn't have to be considered a shared child either, lots of couples each have their own dogs. I think the OP should just let him have this dog and go out and get her own little dog that she can train for herself. He is not depriving her of being able to enjoy her own dog.

What her husband should have done is tell the OP he wanted his own dog to begin with. The OP talked about getting a dog they both could have, that's what was in her own mind, the picture SHE had. Well, he had his own idea and decided he wanted his own dog. The problem is not so much the dog but how the OP and her husband communicated. The OP has talked about how MOST OF THE TIME they got along and she was happy. Well, now there is a challenge and how can SHE work this challenge out?
