In this movie, Jim Dear and Darling give birth to a baby girl named Lulu instead of a boy name Jim Jr. Aunt Sarah comes to dog-sit lady and she did not realize that until she arrived. Jim Dear and Darling decide to take Lulu with them on their trip to see Jim's sister. During the scene with Aunt Sarah's cats, the new song is about them describing the things they are destroying in the house.

In earlier drafts of the original movie, Aunt Sarah was Darling's aunt instead and she was to have antagonistic feelings towards Jim Dear. That is exactly what they do to her in this movie. Jim Dear and Darling are actually the ones who take Lady home from the pound instead of Aunt Sarah and like the original draft Aunt Sarah is not redeemed. Both Jim Dear and Darling tell her how very unsatisfied they were with how she took care of Lady when they get home and she is sent packing immediately.

Tramp is also given a new backstory about how he once had a family, but they deserted him after a new baby was born. Lady also doesn't bond with Lulu until after Jim Dear and Darling take her home from the pound. After Tramp was mistakenly believed to have attacked Lulu when he really was after the Rat, Lady and the other dogs make the horse drawn dogcatcher's carriage turn over and it is Tramp instead of Trusty who gets injured. After Tramp gets up, Jim Dear and Darling tell the dogcatcher not to take Tramp away because he is their dog. The movie ends with Tramp officially becoming a member of the family and Jackie, the new version of Jock, has new puppy siblings that have been adopted from the pound and they hear Trusty's story at the ending.
