Roxie doesn't have an apartment after burrying a bone in the floor, making it collapse. She later becomes Jade's roommate due to this. According to Jade, she and Roxie also live on the same street in the human world, causing the two to go back and forth with each other.
Roxie's energy and recklessness is the focus of multiple episode plots, as her relentless dedication often causes the central conflict for various episodes. She speaks rapidly in excitement which may be overwhelming to new pets, who she loves to see.
Being very dedicated to her owners, and optimistic over the world around her, she can often act naively, leading to mistreatment from Petula's posse or misunderstandings with another pet.
Roxie is a blue-eyed, large eared Boston Terrier with no major identifying markings. She is drawn with small, thick eyebrows, very slightly darker than her fur.
As Roxie maintains an active role in introducing new pets to Paw-Tucket, this mostly garners groans from passers-by, and even her own close friends, who at times grow tired of the act.
Roxie loves her owners and seems to worry a lot about what they think of her. In Pet, Peeved, she tells Jade that she chews her fur if her owners don't tell her "Good girl, Roxie!" enough times per day.
Roxie gets nervous and jumpy when she tries to "eat fancy."
Roxie had floating eyebrows in the first official drawing of the main pets, but in the show and subsequent artwork, her eyebrows are attached to her head.
