“Dog Man: The Musical” plays for one January weekend in San Francisco

Plenty of people – parents and their kids, mostly – have heard of Captain Underpants, the tighty whitey-wearing superhero who fights crime with his unique “wedgie power.”

Perhaps fewer have heard of the spin-off character Dog Man, also created by writer and illustrator Dav Pilkey: He’s a hero with the head of a dog sewn onto the body of a policeman, who also fights crime despite being nonverbal and prone to canine habits like chewing on furniture.

Well, now Dog Man has his own theatrical production.
