let's figue out what my dog is

i posted my puppy about 2 years ago, he's in another thread. but now im curious to see what my fellow dog folks think my other dog is. her papers said boxer greyhound, but i only see the boxer. i'm thinking she is boxer/american pit (the lean one). everybody is always asking what breed is she and commenting how beautiful she is and saying she looks like a pure breed, but i know better lol. she originally came from a shelter in cocke county, tennessee.
