It's a must have for super rich pet owners who want to pamper their pooch: a custom built doggy shower. From California to New York, the super rich are installing these in their mega-homes so their four-legged friends can be bathed in style. The canine shower can even be customized to the exact height of the lucky pooch. We found this high-end dog shower in a mansion in Alpine, N.J., known as "Stone Mansion." What else did we find in Stone Mansion? See No. 7 in our countdown.
