Katie is a young tomboyish girl who works as a pet groomer and doctor at the local pet parlor. As said in "Pups Save a Train", she has a grandmother, but whether she is paternal (on her father's side of the family) or maternal (on her mother's side) is never said. She is seen to be a big sister figure to Alex.
Katie cares about animals and makes sure they are healthy, well-bathed, and happy. Katie is kind, loving and caring.
Katie has pale skin with blue eyes and blonde hair with a red hairband with two pink hearts. She wears a pink striped shirt, blue short pants, and purple shoes. In "Pups Save a Pool Day", Katie wears a pink-striped bathing suit with a white skirt and red slippers. In "Pups and the Ghost Pirate", she dresses up as a witch.
