I thought I had posted an update. So here goes.
I decided to take my original pick because both dogs were interested in a duck wing but the silver one was actually making a retrieve on it, as much as you might expect a 7 week pup to do. The special one just didn't have the coordination. I told my wife that it would never be able to swim. The vet had told them that they should find an older person looking for a companion dog, and the Vet just shrugged her shoulders when they said it might go to a family with 9 kids.
I am going to really try to help them find a home for the special one. She was so sweet and friendly. She would still make a great dog for someone really wanting a pet that needs a mother. My wife doesn't need to be a mother to one more living thing.
I appreciate all the comments. I know I am nutz that is why I came here for some cold truth. Everyone was plenty civil. So thanks again.
