He can not be made in real life, as cutting off a head is pretty much death, and there is no Living Spray in real life. Petey's red cardigan sweater and tie were based on the clothing often worn by beloved children's television host, Fred Rogers from Mister Rogers' Neighborhood. Dog Man also makes an appearance in Frogzilla from Cat Kid Comic Club: Collaborations along with Chief. Turns out Booger Breath adopted the dogs, and his bulldog is chewing on the building.
