The Fox mothership has this story about a woman's dachshund that, "gnawed off her right big toe while she was asleep."
She is 56 and diabetic--hence the lack of feeling in her toe.
The dog was 1-year-old--was, because of the lack of feeling in her heart.
She had the dog put down, "for the safety of others." (Emphasis mine.)
Yeah, riiight. She was actually afraid that she'd be left without a leg to stand on.
At least her dogs won't be barkin' now.
