Granddad Dog is a character in Peppa Pig.
Granddad dog appears to be smart, with a knowledge in both sea-related things and mechanic work. He has a bit of a short temper when dealing with the other Grandfathers, and sometimes bickers with Grandpa Pig and insults his skills as a captain - as Grandpa Pig does with him, but he cares about his friend a great deal. He is kind to the children and women however.
A pale grey-brown dog with wrinkles, brown lips, and white facial hair. His cheeks are dull light red, and he has a black nose. He wears a dull, dark green-blue outfit with black shoes. Usually he wears a hat, either that for sailing or mechanic work.
