Dogs aren't always the most alert, but when they realize something is awry, they're on it.

Much like the corgi in this video, Turbo (the dogs name) is just chilling on the lawn while the owner takes some video.

Little did the owner know that she was going to catch the dog finally realizing what the dog thought was a rock isn't a rock at all, but a turtle.

Now for what I love about the video. The audible yawn "squeak" from Turbo, and that "What? Did you see that? What is that?" expression he had when he saw the "rock" start to move.
