You can help Walter a great deal if you can manage to put
on a happy & confident face when you take him there. You know
that you'll be back & he'll be a lot less stressed if you leave him
with the feeling that "I'll be right back". Dog's have no concept
of time as we do. I hope they allow you to bring along a shirt
or something with your scent on it for the overnight stay. It will
help too. Pretend you're an actor & give a great performance of
confidence & "rightness" to his visit & wait till you are back outside to worry or fret about it. Walter will take his que from
you. Let us know how it goes, o. k.?
