White Council
The guardian statues that the White Council uses to guard meeting entrances are modeled after Foo Dogs. In "Turn Coat", Ancient Mai is shocked that Harry has a Foo dog (exclaiming, "Where did you "get" such a thing? And "why" were you allowed to keep it?"), apparently not taking Mouse's wishes into account. However, she and several other wizards in attendance confirm his reliability as a witness, and Harry uses him and a set of surveillance photos to expose a traitor within the White Council.
