The name given to a dog found by Brian Tanner. Alfina's true owner is a girl named Hannah, whose father taught Alfina to do all the wrong tricks (i.e. respond to the wrong vocal commands). The dog's real name is Francesca.
ALF becomes jealous of the attention and affection that Alfina gets from the family and gives the dog to a mean old lady named Ethel Buttonwood, who only pretended the dog was hers so she could sell it.
