Long story short, I believe these are the remains of a stray dog that had been hanging around the neighborhood since Saturday. Last night she was alive and somewhat well. She would only get wishing five feet or so of you if you had food. That was it. This morning, I was driving to the gas station and there was an SUV parked about where I had seen her bedded down last night. It looked as though he was petting her, but I didn't really slow down and couldn't see. Later, it dawned on me that he may have hit her by accident and that's how he was able to get that close to her. This afternoon I went to see if she was still around and she wasn't. Then I stepped on this (it was dark).
That's her paw, about five feet from where she was bedded down the night before. The rest of the pictures show ribs, teeth and vertebrae and what looks like another part of her leg. There was no skull, no other skin or fur and, most importantly, no blood.
I am guessing she got hit, made it 200 feet or so, and died. Then, vultures? Some other type of scavenger bird? We have a fox in the area, but they wouldn't eat a dead dog. Any guesses at what would pick a dog clean, leave no blood or skin and might take the skull and bigger bones away?
