In a recent article by Deborah Huth Price of The Berthoud Recorder, Castle Cleaning and Oriental Rug Company located in Berthoud, Colorado, one of the more popular staff members is a Golden Retriever by the name of "Dude."
Why have a dog on staff? Rugs which come in for cleaning need special attention prior to the process. Sometimes UV lights are used to located areas of soiling which are not immediately apparent to the naked eye. Owner of Castle Cleaning and oriental rug Co., Phil Auserehl, stated that "Dude" is 100% competent when it comes to locating urine and other stained areas of customers rugs.
Apparently Dude can do several other things, including greeting customers with a paw shake, and even do simple math.
