Update
Robbie continues to play the shy boy in that he still refuses to take a treat from the hand but we are making painfully slow progress with the cuddles.
He will now allow us to sit him on our knee for a very short time only but if you attempt to cuddle him he is away to hide in his crate.
We feel we are making progress and will continue to help him as much as we can but he is one happy little puppy who plays really rough with the big ones and can give as much as he gets.
We love him so much just as much as we love the other three.
