Looking for the fic where Tony thinks he's a dog

[bwolf-20011.livejournal.com]

A while ago I ran across a fanfic where something happened to Tony, I think a hit on the head or something and when he comes to, he starts acting like a dog. The other Avengers are confused and they are left letting Tony run about acting like a dog until he can snap out of it or it wears off. I recall it was a Steve/Tony pairing which I'm not crazy about but the subject of Tony thinking he's a dog (not literally turned into one) was interesting. I think it went as far as Steve giving him a bath.
If anyone knows this fic and where to find it, I'd appreciate it. If there's another such story out there with this subject, i'll gladly take it :)
