premise: My family 's dog since I was in high school , Gingersnap , was put down this morning at 9:30 . Ginger was a big sweetie with a very expressive face , stubby legs with big paws , and a wagging tail that would beat you half to death . She was diagnosed with lymphoma last spring , and although she lived well with it for several months , she was starting to obviously suffer for most of the time . What may have caused Gingersnap to pass away ?
hypothesis: She lost her legs .
