Official Description

(Can only be found in Mothering Heights)

He has the head of a Dog, The body of a man, and the heart of a hero!!! He is employed as a cop, and is occupied at home with the creativity of Lil' Petey and 80-HD.


  • Kindness


  • Easily distracted


Being Greg the Dog with Officer Knight's body from the neck down, his personality is that of Greg's. Dog Man is very playful and likes to greet visitors with a friendly lick and jump like he does to Chief. Even though chief hates it. But when trouble arises, Dog Man acts seriously, just like Officer Knight did. He always gets the job done, no matter what it takes. He is also very cheerful and happy when nothing bad is happening in the city. He is loving and caring to everyone, especially Li'l Petey, whom he adopted. He also cares for Petey at times when he is not acting cunning and evil, such as in the 5th Dog Man book, Dog Man: Lord of the FLEAS. He is mute, although he can still bark, growl, et cetera, like a dog, most likely because he has Greg's head. He is not an anthropomorphic dog; there aren't any anthropomorphic dogs in the series either.


The Wrath of Petey


One day, due to his stinky nature, a cop tells Dog Man that he needs a bath. Dog Man then runs away, due to the fact that he hates baths. The cops search all over the city, but Dog Man is nowhere to be seen. Dog Man in hiding, discovers that Petey had escaped, which made him feel guilty. Dog Man searched for Petey and found his hideout. But Petey had been waiting with a hose, and said, "it's bath time!" Dog Man dug a hole to get away from him, but Petey just followed him anyways. Dog Man dug under the zoo, and came up to the skunk cage. The skunks sprayed on him, and Dog Man ran away, and Petey hates the smell, holds his nose, and runs away in disgust. Petey gets caught in a cop's net and goes to jail. Dog Man takes a bath and is clean for the first time.

The Tongue of Justice


Dog Man accidentally barfs on Chief's chair, causing him to get angry. He tells Dog Man to "straighten up or else." Then, Petey escapes and creates an evil air freshener and puts in the cop's cars, and they all become mindless zombies. Dog Man, however, liked to put his head out the window, so he never smelled it. Dog Man chases Petey into his lab, and spots the toilet. Dog Man drinks the toilet water and comes upstairs, surrounded by Petey and his zombies. Petey says he has his antidote, but he hid it in his toilet bowl. Dog Man realizes that he drank the antidote the whole time, so he barfs up all of the liquid, the cops are no longer zombies, and Petey is put back into Cat Jail.
