Dumbledore an animagus?

I was reading book 2 and noticed that Tom Riddle said that 
Dumbledore was the transfiguration professor. This made me wonder D 
could possibly be an animagus, because if he is interested in 
transfiguration, why not? McGonagall, who is the transfiguration 
professor is is an animagus. 

But then I remembered that about the list of registered animagi that 
Hermione was talking about in book 3, and presumably it would have 
been mentioned if Dumbledore was listed on it.  I can't see 
Dumbledore being an unregistered animagus, so I decided there was 
nothing in my theory.

Also, if Dumbledore *was* an animagus, what type of animal do you 
think he would turn into?
