"Happy Dan the Whistling Dog," by Ward Greene, was published in a 1945 edition of Cosmopolitan magazine.

Cocker Spaniels were originally bred as hunting dogs in the United Kingdom, with the term cocker deriving from their use to hunt the Eurasian woodcock.

Tramp likes to dine on scraps from Tony's Italian restaurant.

On Christmas morning, 1909, in a quaint Midwestern town, Jim Dear gives his wife Darling an American Cocker Spaniel puppy that she names Lady.

Their change in behavior is due to Darling expecting a baby.

The dog catcher captures Lady, Tramp, Peg, and Bull at various times throughout the movie.

Lady enjoys a happy life with Jim & Darling and befriends two local neighborhood dogs, Jock, a Scottish terrier, and Trusty, a bloodhound.

After the baby is born, Jim Dear and Darling leave for a trip, with Aunt Sarah looking after the baby and the house.

The spaghetti scene almost didn't happen. It was cut from the film's first storyboards by Walt Disney himself. He wanted the dogs to have human emotions but couldn't wrap his head around the idea of two dogs romantically sharing a strand of spaghetti. Fortunately, animator Frank Thomas worked up a rough version of the scene that changed Disney's mind.

Aunt Sarah's two trouble-making Siamese cats deliberately mess up the house and trick her into thinking that Lady attacked them. Aunt Sarah then takes Lady to a pet shop to get a muzzle.
