Mark Dearinger, owner of Dearinger Salon at 6875 La Jolla Blvd., recently announced that his Yorkshire terrier, Mini Cooper, won Best of Breed at the AKC/Eukanuba National Championship in Long Beach last month. Cooper was shown by handler Kirsten McGregor, while Dearinger was showing his other top-ranked Yorkie, Carlton. Dearinger said maintenance of Yorkies’ coats requires daily attention, which he provides with expertise from his salon. He said he enjoys having a hobby that allows him to bond with the dogs. “The dogs have to be very happy and healthy and they have to like doing shows in order to do well,” he said. “Keeping them happy is part of the job. They need to feel taken care of and catered to.” Dearinger has been showing his Yorkshire terriers in competitions across the U.S. for years, often taking top prizes. He and his Yorkies also have been featured in national magazines.
