There is a website that offers an online test to determine what your dog's personality is. Note that I have not tried this website out, so please don't take this as an endorsement. But, according to its press release, the test, which is referred to the "Canine Behavior Type Index®" offers 26 questions about your dog. It then produces a report describing your dog's personality.

The type index was developed by Dr. Jacqeline Perkins, an animal behaviorist, after studying dogs in domestic settings for years. It was incorporated into this website and marketed as a "game" which ultimately reveals your dog's inner pooch. You can visit the website to take a look: http://www.petconnectgame.com

There is a fee of $9.95 (Australian Dollars) to play the game.
