It is apparently a more complex spell than the simple circle of dust. Deaton can allow werewolves into and out of the back part of the office, kind of like inviting a vampire into your house. The waiitng room is also not warded at all, which is why any werewolf can walk in there, but not cross into the back office.

I think that Deaton didn't flinch when Peter threw the chair because you do not show fear to an angry wolf, and besides, Peter wouldn't get anything out of Deaton if he injured him behind the barrier because he still wouldn't have been able to cross it to reach Deaton. So if Deaton did not show fear of being hurt, then there was no further point to threatening him.

Since Deucalion was able to spear Morrell through a Mountain Ash barrier, I assume that non-magical objects thrown by werewolves can bypass it. Also, Deaton's Mountain Ash wards provided no protection against Jennifer's own druidic magic and she was able to snatch him right out of the examination room.
