exactly the same thing only with fur. he isnt being tramatized by crate time so dont worry about it. For sanity's sake he needs it. Shasta would go and go and go and after a few crate sessions she started to chill on her own outside of it. That pup will go until she drops, literally. She'll just skid to a stop, flop down and start snoring a minute later. Dont worry. You're pup sounds perfectly normal.
