Begin by shampooing and brushing the dog to remove any matted hair. When cutting a dog's coat down to 1/2 inch or less, you must use the pet attachment to keep the dog's skin in place. Do not cut more than 1/2 inch of hair off at a time.
Patented in 1986 by Rick E. Hunts, the Flowbee is a home haircutting system with recessed blades that connects to a vacuum. The suction of the vacuum pulls the hair into the blades to the length you select and then cuts it in 1/4-inch increments. Hair ranging from 1/2 inch to 6 inches long can be cut, and additional spacers are available for longer lengths of hair. According to the Flowbee website, a major benefit is that it cuts hair evenly and precisely with minimal effort, eliminating the need to visit expensive hair salons and pet groomers.
Use the Flowbee on cats and dogs with hair that is at least 1/2-inch long. At one point, a Pet Groomer Flowbee was available on the market, but it is no longer available as of 2015. A pet attachment is available to use with the regular Flowbee product. Purchase the Flowbee online and in some speciality stores. An instructional video is available from the manufacturer's website.
