The doctor is a veterinarian in Bedrock.
He's rather incompetent, not knowing who to treat. He tried to make jokes, but he just came off as annoying.
He was called on by Wilma Flintstone when Fred was knocked out cold by a rock-hard car polish bottle. He thought Barney & Betty Rubble were the patients, before seeing Fred, who simply thought he was sleeping. He thought it was the cause of Wilma and tried to correct her method of what she should've done, so she shouted in his stethoscope to get lost. It turned out that he wasn't fit for treating humans, as he was a veterinarian.
