Are werewolves loners or come in packs and colonies?

I have another question about werewolf transformations that I’m not completly understanding.  When a werewolf transforms, do they completely transform into a wolf, or do they transform into a human-wolf hybrid (in other words, do they stand upright and still look like a human, or do they actually transform completely into wolves?)  I myself like to think that werewolves are human-wolf hybrids…but maybe they do transform completely into wolves.   And if werewolves transform completely into wolves, do they run with wolf packs? Do wolves accept them as one of their own?

Here’s what I think – werewolves tranform into a wolf-human hybrid. They are not accepted by real wolves. And they are not accepted by humans either.  But I do think that if a werewolf finds another werewolf they can form packs or colonies.  So yes, maybe werewolf are loners UNTIL they find other werewolves, then they become social.
