I purchased a plug in called Comfort Zone. I think it help. It is a plug in
with a small bottle attached that omits a scent like the mother dog gives
off to her off spring! If he is confined in one room it might help. Just keep
the plug in in a plug where he can not get to it. I found it in the Foster Smith
catalog. Petco & Petsmart also carry it. You can not smell anything but
the pup will.
