Is there any reason why the two dogs can be crated beside or near each other? And this can be case of SA starting. Agreed, put him in the crate ignore him and don't hover to close, ignore is ignore, the second he is quiet he gets to come out. Also agree with the c/r for quiet, also play the Your In, Your Out game. I would also recommend SG's Crate Games BUT he has to be quiet and not stressing in a crate before you start that program.
Ok, going to rant here...........why in hell do so many breeders not crate their puppies BEFORE they go to their new homes. It isn't fair to the pup on any level nor to the new owners either. So easy to purchase a crate, train the pup in it and then send it to the new home already crated trained with a mat and toys that smell familiar.
