Fic!Search PetXander

I'm looking for either consort or pet!xander fics which involve Angel or Angelus in some way. Not as the romantic interest (I leave that one all up to Spike) but either forcing the bond or helping afterwards. I've read quite a few, but am looking for suggestions. Longer fics are love.

I also wanted to know if anyone knew of any Pet-type fics out there with Spike as the submissive one rather than Xander? I've been unsucessful in my search for them if they exist...
