In "Lady and the Tramp II: Scamp's Adventure," a significant element that was removed from the original "Lady and the Tramp" is the more detailed exploration of the character dynamics and backstories of the supporting characters, such as Jock and Trusty. The sequel focuses primarily on Scamp's adventures and his quest for freedom, which shifts the narrative away from the romance and themes of loyalty present in the original film. As a result, some of the emotional depth and character development found in the first movie is less pronounced in the sequel.

In "Lady and the Tramp II: Scamp's Adventure," Scamp is portrayed as a mixed-breed dog, primarily resembling an American Staffordshire Terrier or a similar breed. He is the son of Lady, an American Cocker Spaniel, and Tramp, a mutt. The film follows Scamp's adventures as he seeks freedom and independence, embodying the playful spirit of a young pup while also exploring themes of family and belonging.

There is no "Lady and the Tramp 3." The sequel to the original "Lady and the Tramp," titled "Lady and the Tramp II: Scamp's Adventure," was released in 2001 and focuses on the adventures of Lady and Tramp's son, Scamp. While there has been no official third installment, the original film remains popular, and the characters have made appearances in other Disney media.
