You have to wonder what this dog was thinking... 

He went from enjoying a nice day out on the water with his owner to spinning endlessly in an out-of-control boat.

The video, posted to YouTube, makes it look like the dog is doing donuts in the raft-like vessel.

The dog's dizzying ordeal started when his owner fell overboard off the coast of Australia.

The man swam to safety, leaving his canine friend spinning, and spinning, and spinning some more.

The dog was eventually rescued.
