As hilarious as this may be. I hope that there was no damage to the dog's teeth while he was dropping cinderblocks on the Mormons.

If you live in Florida, you can try subbing the bricks with coconuts. Sound crazy, but the fibers of the husk can help floss your dog's teeth. My neighbor's bulldog were constantly chewing on coconuts, to the point where they were giving us the nut as they had too many.
