Dog breed
The English Cocker Spaniel is a breed of gun dog. It is noteworthy for producing one of the most varied numbers of pups in a litter among all dog breeds. The English Cocker Spaniel is an active, good-natured, sporting dog standing well up at the withers and compactly built. There are "field" or "working" cockers and "house" cockers. It is one of several varieties of spaniel and is the foundation of its American cousin, the American Cocker Spaniel. The English Cocker is closer to the working-dog form of the Field Spaniel and the English Springer Spaniel. English Cocker Spaniels are also known as the "Merry Spaniel" due to their constantly wagging tails.
Outside the US, the breed is usually known simply as the Cocker Spaniel, as is the American Cocker Spaniel within the US. The OED states that the word cocker is derived from the fact the breed was used to flush woodcocks.
Temperament: The English Cocker Spaniel ranks 18th in Stanley Coren's The Intelligence of Dogs, being of excellent working/obedience intelligence.
With a good level of socialisation at an early age, Cocker Spaniels can get along well with people, children, other dogs and other pets. This breed seems to have a perpetually wagging tail and prefers to be around people; it is not best suited to the backyard alone. Cockers can be easily stressed by loud noises and by rough treatment or handling. When trained with a soft hand and plentiful rewards, the Cocker Spaniel will be an obedient and loving companion with a happy, cheerful nature.
Description: The English Cocker Spaniel is a sturdy, compact and well-balanced dog. It has a characteristic expression showing intelligence and alertness. Its eyes should be dark and its lobular ears should reach "a bit past" the tip of the nose when pulled forward. Today, a significant difference in appearance exists between field-bred and conformation show-bred dogs. The Cocker's tail is customarily docked in North America. In countries where docking is legal, the tail is generally docked at about 4–5 inches (10–13 cm) in field-bred dogs while show dogs are generally docked closer to the body. Docking is now illegal in Australia and South Africa. In England and Wales, docking can only be carried out on dogs where the owners have proved that the dogs will be used as working or shooting dogs.
The breed standard indicates that the males of the breed are on average between 15.5 and 16 inches (39 and 41 cm) at the withers with the females a little smaller, growing to between 15 and 15.5 inches (38 and 39 cm). Both males and females of the breed weigh approximately 13–14.5 kilograms (29–32 lb). American Cocker Spaniels are smaller, with males being on average between 14.25 and 15.5 inches (36.2 and 39.4 cm) and females again being smaller on average at between 13.5 and 14.5 inches (34 and 37 cm), both weighing approximately 11–13 kilograms (24–29 lb).
The English Cocker Spaniel is similar to the English Springer Spaniel and at first glance, the only major difference is the larger size of the Springer. However, English Cockers also tend to have longer, and lower-set ears than English Springers. In addition Springers also tend to have a longer muzzle, their eyes are not as prominent and the coat is less abundant.
Health: A 2022 UK study of veterinary clinic data found a life expectancy of 11.31 years slightly above the 11.21 overall average but below the 11.82 average for crossbreeds. A 2024 UK study found a life expectancy of 13.3 years for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreeds. A 2024 Italian study found a life expectancy of 13 years for the breed compared to 10 years overall.
A 1996 study made by the University of Cambridge surveying 932 English Cocker Spaniel households throughout Britain found owners to report higher aggression in different coloured English Cocker Spaniels depending on the scenario. A 2009 study by Spanish researchers at the Autonomous University of Barcelona found that English Cocker Spaniels were more frequently produced to a referral clinic for aggression and that they had more impulsive attacks than other dogs. However, the notion of 'cocker rage' has been dismissed as a myth.
A review of 2,318 English Cocker Spainels attending veterinary care found the most common conditions to be: periodontal disease with 20.97% prevalence, otitis externa with 10.09% prevalence, obesity with 9.88% prevalence, anal sac impaction with 8.07% prevalence, diarrhoea with 4.87% prevalence, and aggression with 4.01% prevalence.
The English Cocker Spaniel is predisposed to chronic hepatitis, with one study finding the breed to be 2.78 times more likely to acquire the disease.
The English Cocker Spaniel is one of the more commonly affected breeds for progressive rod-cone degeneration. An autosomal recessive mutation in the PRCD gene is responsible for the condition in the breed.
History: Spaniel type dogs have been found in art and literature for almost 500 years. Initially, spaniels in England were divided among land spaniels and water spaniels. The differentiation among the spaniels that led to the breeds that we see today did not begin until the mid-19th century. During this time, the land spaniels became a bit more specialised and divisions among the types were made based upon weight. According to the 1840 Encyclopedia of Rural Sports, Cockers were 12–20 lb (5.5–[dose — ask your vet]). At this time it was not uncommon for Cockers and Springers to come from the same litter. Even a puppy from a "Toy" sized lineage could grow to be a springer.
There is no indication from these early sources that spaniels were used to retrieve game. Rather they were used to drive the game toward the guns.
During the 1850s and 1860s, other types of Cockers were recorded. There were Welsh Springer Spaniels and Devonshire Cockers. Additionally, small dogs from Sussex Spaniel litters were called Cockers. In 1874 the first stud books were published by the newly formed kennel club. Any spaniel under 25 lb ([dose — ask your vet]) was placed in the Cocker breeding pool, however, the Welsh Cocker was reclassified as a Springer in 1903 due to its larger size and shorter ear.
