Ninja dog, or coincidence? Read.

A couple weeks ago, my dog learned a new trick, called "roll over". She's really good at this trick and she rolls over all the time, even when you don't tell her to do so. today, I said to my dog "Scarlett, roll over.", and so she did just that.

Here's the good part: Something interesting happened after that. Scarlett rolled over one more time and proceeded to spit a silver dollar-sized rock at my face. She got up and ran away while I sat on the ground with my mouth gaping in amazement.

She could be the next Rin-Tin-Tin...with spots and a bobbed tail.
