9. Lady and Tramp
Final Score: 26/40
Odds of meeting: A mutt from across the tracks and a pampered cocker spaniel may at first seem like an odd couple unlikely to meet, but these two prove that opposites attract.
Obstacles overcome: Si and Am wreack some havoc; Tramp's recklessness endangers Lady, and aunt Sarah muzzles the poor girl, who ends up in the pound.
Friendship: Even wildly different personalities can get along when there is understanding and compromise.
Likeability as a couple: It doesn't get much cuter than two dogs sharing a meal at the back of a restaurant.
