When we were invited into the wolf enclosure we were instructed to sit down because the wolves would otherwise knock us over. The wolf greeting is to come up, nibble and lick your teeth, and we were told to grimace with our teeth exposed, and lips drawn back ... and not show fear. The wolves were much larger than dogs, and had yellow eyes. We all sat in a line, and the wolves came to us and each in turn politely, if not somewhat aggressively, licked our teeth.
