A Pup Named Scooby-Doo

Season two


Ruby as a puppy.

Ruby attended the Doo family reunion at the Knittingham Puppy Farm. As a puppy, she related a lot to Daphne Blake, sharing a common interest in fashion.[1]

Scooby-Doo and Scrappy-Doo (second series)

She gave birth to Scrappy at St. Bernard's Memorial Hospital. When she was being taken to the delivery room, she told Shaggy and Scooby not to worry, but when she entered they both fainted. Once the baby was born, he attacked the doctor for swatting him, who then says he was a scrappy little tyke, which she overheard and decided to name him Scrappy-Doo. Later, Scrappy told her that he couldn't find anyone to play with, then they saw Shaggy and Scooby getting chased by an angry hospital orderly, with Ruby explaining to her son who they were, so the newborn went after them. After Shaggy and Scooby got beat up, Scrappy asked if he could travel with them, to which she simply said, "We'll see."[2]
