The Benadryl knocked him out last night. He fell asleep on my bed rather than go into is crate (which he prefers). At 2am he woke up crying so I was concerned. I finally figured out that Cooper was laying with his squeaky toy

I gave him the squeaky toy and he played in the living room from 2-3am
Last night it was tough to keep him from licking is leg. I put a leg warmer on him and that seemed to work! Thanks for all the concern. I love YT.
