[General Fantasy] Could a vampire survive on black pudding?

It seems like a much easier way to get blood then from people- but could they actually survive on it? Or does the blood need to be "fresh" or not from animals?

Depends. There are *many* different definitions of "vampire" and every universe seems to have its own. The ones from *Twilight* probably couldn't (given Meyer's "dead blood" excuse for why menstruation doesn't attract vampires), but Dracula might be able to.
