Details about her early life are unknown aside from being born a stray. However, it is known that she eventually joined up with Riley and his gang of stray dogs. She apparently has a rivalry with Ashcan and Pete, two vicious junkyard dogs, given her comments to them. She eventually decides to quit Riley's Gang (which Riley presumably allowed her to do) and travels over to Chance's house, using her smell and her heart, and is adopted as a member of the Seaver family.
