he's a little younger, having turned 27 last month but also had a few issues when he first woke up as human. he too has gotten much better about it, though he still sometimes needs to be reminded he can't exactly drop his pants and go to the bathroom in public. maybe pre-spell sven was/is a volunteer for your guys rescue, and then when the spell happened he could have noticed a drastic change because i imagine sven would be apprehensive about canines at first, given his whole issue with wolves and whatnot. though i'm sure he'd have gotten over that by now.
