American Cocker Spaniel

Form and Function

The smallest member of the Sporting Group, the Cocker should be compact and sturdy. Their gait is ground covering, strong, and effortless. The coat is silky, flat or slightly wavy, not overly long. Excessive coat can hinder the dog in the field. The head and expression are hallmarks of the breed; the expression is soft and appealing. The Cocker should still be able to spend a day in the field and should be balanced and athletic. It is true, however, that most Cockers now have too much coat for field work.

Date of Origin



The American version of the Cocker Spaniel is derived from the English Cocker Spaniel. In the late 1800s, many English Cockers were brought to America, but American hunters preferred a slightly smaller dog to hunt quail and other small game birds. The American Cocker is smaller, with a rounder head, shorter muzzle, and more profuse coat than its English ancestor. Just how this smaller Cocker was developed is not entirely clear; some credit the dog Obo 2nd, born around 1880, as the first true American Cocker. But other evidence points to crosses of the English Cocker with even smaller toy spaniels (that nonetheless arose from the same ancestral stock).

Initially the English and American Cocker Spaniels were considered varieties of the same breed, but they were officially separated by the AKC in 1935. Although Cockers were already popular, after the separation the American Cocker surged in popularity and has remained one of the most popular breeds of all time in America. In fact, it was the most popular breed for many years. So popular was it that it was eventually divided into three color varieties: black, particolor, and ASCOB, which stands for Any Solid Color Other than Black. Only recently has its popularity spread to England, where it was recognized by the English Kennel Club in 1968, and it has gained admirers steadily since.


This breed is known as the “merry” Cocker, and the name is most fitting. He is playful, cheerful, amiable, sweet, sensitive, willing to please, and responsive to his family’s wishes. He is not known for retaining his hunting instincts, but he is inquisitive and will appreciate a country outing. He is equally at home in the city and will happily walk on leash for his exercise needs. Some bark a lot; some are overly submissive.


Although he enjoys a romp, the Cocker can receive adequate exercise with a long daily walk on a leash. The coat of the Cocker requires a greater commitment than that of most breeds, although pets can be clipped short. In order to maintain a nice coat, he will need to be brushed and combed two to three times a week, in addition to professional clipping and scissoring every month. Special attention must be paid to ear and eye cleanliness in this breed. The profusely coated feet tend to carry debris. Cockers have a tendency to become overweight.
