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.[1] He's been with the Louds before Lincoln met Clyde, as shown in "Deal Me Out". 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.
