Charles is the Loud family's pet dog. He was adopted into the family when Lana found him and cried until they agreed to keep him. He has been with the Louds before Lincoln met Clyde. Although he generally does not play a large role, Charles makes frequent cameo appearances throughout the series. Because he seems to hang in Lincoln's room, and around Lincoln most of the time, it is possible he is mostly Lincoln's dog.
Charles is a Pitbull Terrier dog with small white ears, a small black nose, and a black spot over his left eye. He has freckles and a black concentric circle on his back.
