" With their ever-wagging tails, handsome appearance, soulful eyes, and friendly temperament, the merry Cocker Spaniel has deservedly often been in the ranks of most popular dog breed. In fact, the breed was number one in AKC rankings from the late 1930s to the 1950s, and then again during the mid-1980s. " ​        
 
I would say, as soon as people realize that doodles DO shed (some of them shed enormously), cockers will be the most popular breed again!
