Cocker Spaniel
Cocker Spaniels split into American and English types with distinct sizes, coats, and histories. This article details their hunting origins, physical differences, and health considerations for owners.
Two distinct breeds exist under the name Cocker Spaniel: the American Cocker Spaniel and the English Cocker Spaniel. While they share a common hunting ancestry, they diverged significantly in the 20th century into separate breeds with different physical standards and temperaments.
Origin and the split from Springer Spaniels
The term "cocker" derives from the breed's original purpose: hunting the Eurasian woodcock. Spaniels were first mentioned in the 14th century by Gaston III, Count of Foix, and by the 19th century, the "cocker" was a type of small field spaniel. Prior to 1901, the only requirement for a dog to be classed as a Cocker Spaniel was that it weighed less than 25 pounds (11 kg). Larger dogs were classed as Springer Spaniels.
The separation into distinct breeds was driven by selective breeding rather than a single genetic event. In the United States, the English Cocker was recognized as a separate breed in 1946, while the American type was recognized in the UK in 1970. Two dogs are considered the foundation sires of both modern breeds: Ch. Obo, the father of the modern English Cocker, and his son, Ch. Obo II, the progenitor of the American Cocker.
Physical differences define the breeds
The major difference between the two is that the American Cocker is smaller with a shorter back, a domed head, and a shorter muzzle, while the English variety is taller with a narrower head and chest. The American Cocker was bred smaller because American woodcocks are smaller than their European relatives, and breeders later favored a more stylish appearance.
According to the AKC, the American Cocker stands between 14.5 and 15.5 inches (37–39 cm) for males and 13.5–14.5 inches (34–37 cm) for females, weighing typically 24 to 30 pounds (11–14 kg). The English Cocker is slightly larger, standing 15.5–16.0 inches (39–41 cm) for males and 15.0–15.5 inches (38–39 cm) for females, with a show dog weight of 28–32 pounds (13–15 kg).
Show versus working strains
In the United Kingdom, two distinct strains of the English Cocker Spaniel have developed: the show strain and the working strain. Show Cockers are bred to meet breed standards, featuring domed skulls, longer ears, and a thicker, silkier coat with prominent feathering on the legs, chest, and tail. Working Cockers are bred for field performance, resulting in dogs that are slightly taller and leaner with flatter skulls, shorter ears, and shorter, finer coats.
Working Cockers have minimal feathering to reduce debris caught during field work, and they possess higher stamina and a more intense drive to work. While both strains share the friendly and affectionate traits of the breed, the high energy levels of working Cockers can make them more demanding as household pets without proper training and mental stimulation.
Coat colors and rare occurrences
Cocker Spaniel coats occur in a variety of colors, including black, liver, red, and golden in solids. Variations include black and tan, liver and tan, roans, tricolors, and solid colors with white markings. While an all-white cocker is usually bred by selective breeding of very light golden strains, they can appear uncommonly in dark-colored lines.
A noted occurrence of this happened in 1943, when a grandson of My Own Brucie, a Westminster Kennel Club Dog Show winner, was born all-white. The American Cocker Spaniel is judged in three separate breed classes under AKC rules: "black", "parti-color", and "any solid color other than black" (ASCOB).
Popularity and show history
The English Cocker Spaniel is the most popular dog breed for showing in the UK at Crufts, winning Best in Show seven times between 1928 and 2009. The American Cocker Spaniel has won Best in Show at the Westminster Kennel Club Dog Show four times. In terms of general popularity, the American Cocker was the most popular dog in America for 25 years, ranking number one from 1936 to 1952 and again from 1983 to 1990.
In 2009, the American Cocker was ranked 23rd-most popular in the US, a decrease from its 13th place ranking in 1999. In the UK, the American Cocker is far less popular than its English relative, with 322 registrations compared to the English Cocker's 22,211 in 2009. The English Cocker remains the second most popular breed in the UK, beaten only by the Labrador Retriever.
Health and temperament
The English Cocker Spaniel is an active, good-natured, sporting dog known as the "Merry Spaniel" due to its constantly wagging tail. It is noteworthy for producing one of the most varied numbers of pups in a litter among all dog breeds. Both breeds share similar coat colors and health issues, though specific genetic risks can vary by line.
Owners should be aware that the physical differences between show and working lines affect their needs. While show dogs require regular grooming to maintain their luxurious coats, working dogs require intense physical and mental activity to prevent behavioral issues stemming from their high drive. The breed's history as a gun dog means they are naturally inclined to use their sense of smell to flush birds and retrieve game with a soft mouth.
