Every day has its dog. In the mid-’80s, the cocker overtook the poodle as most popular breed. Last year, the Labrador retriever sprang into second. Though the cocker is expected to remain the prime canine, style-wise the BICHON FRISE, a descendant of the water spaniel, will be the new hot dog, perhaps reaching the Top Five by the late ’90s. The affectionate little devil (8″ to 12″ tall, 12 lbs. to 15 lbs.) was a favorite of European royalty in the 1500s and was often portrayed by Goya. The French name translates as curly lap-dog, and laps it now adorns include those of Kathie Lee Gifford, Betty White and Andrea Evans.
