He is a Great Dane that looks exactly like Scooby. In Scooby's puppy years, he wears square framed glasses like his other son, Skippy-Doo, and a tie. When Scooby grew up, he wears a small vest and his fur has wrinkles.
Much like Scooby, he enjoys eating and can be scared easy, but when Buster McMuttMauler cornered a puppy, he bravely came to the rescue. He loves his family and children very much. He also hated wearing the Doo family collar which rubbed off on his oldest son, Scooby.
He waited impatiently for the birth of his son, Scooby, at Dooville Veterinary Hospital As soon he was informed by the nurse that the baby was born and it was a boy, he happily kissed her, gave her a dog biscuit and ran to his wife inside the hospital room. There, he heard the baby saying "Scooby-Doo", so he decided to name him that. 
While he and Mama-Doo were on a date they saw Buster McMuttMauler threatening a puppy and came to the rescue, they chased him to his truck and laughed when his boss took him to prison for stealing collars.
