Underdog, also known as Shoeshine, is a canine superhero and the titular protagonist of the live-action film of the same name. He was previously a normal dog until he was exposed to a variety of DNA of different animals, which modifies the beagle's DNA and gives him supernatural powers and abilities (see character infobox). He is able to speak like a regular human. He is also able to emit a bark that is so strong it can shatter glass.
