Number one in England, the English Cocker Spaniel is cheerful, robust and sporty: with great intelligence and superior skill in the field; the English Cocker Spaniel is easy to train and lives to please its owner. 
A sports dog with a lot of bone and substance, the English Cocker Spaniel is an active dog, with a compact build. The male is between 39 and 41 cm tall; the female, between 38 and 39 cm; the male weighs between 14 and 17 kg, the female, between 12 and 14.5 kg. Mostly, the English Cocker Spaniel is a well balanced dog, with a sweet expression, but alert and graceful. The head is strong but never coarse, with soft angles. The skull is arched and slightly flat. The eyes are medium sized and full, well separated, and the eyelids well adjusted. The ears, low inserted, flat on the head and covered in long silky hair. The muzzle is well padded and same length as the skull. The neck, is elegant and muscled, with no dewlap; the chest is deep and somewhat wide; the kidneys, short and wide. The tail is inserted slightly lower than the back line, it is usually docked, but never too short, to the point it is visible. Moderate front and back angulations; straight forelegs; wide thighs. The coat is smooth or slightly wavy and silky to the touch. It has abundant long hair, not as much as the American Cocker, and never so much it can make field work difficult. Solid colors include golden, black and liver; the particolor should be defined, spattered or roan; tan color is admitted in blacks, livers and particolors; patches in the particolor body should be defined and symmetrical. In unicolors, white is only admitted in the chest.
The English Cocker Spaniel’s hair, although not as abundant as its American cousin, has good stripes and requires certain dedication. 
Sweet and docile, the English Cocker Spaniel is a charming family oriented dog. Children should be properly instructed to treat the puppy carefully and let it rest when asleep. The English Cocker has less hair than the American, but still needs daily attention. The English Cocker tends to be a polite manipulator, making the most of its sweet expression to get away with it. Its called sad eyes are an erroneous concept: the English Cocker is a cheerful breed above all.
The English Cocker Spaniel’s sweet temperament is as vital as its ability to walk with a leash, scaring birds or sit upon command. Observe your puppy’s parents: Is the mother happy, kind, and sociable? Own. Helyne Copper.
The average per litter is five puppies, although there are larger litters. The weigh upon birth is barely 56 to 120 g. The puppy grows quickly during the first six months, afterwards it develops more slowly. The English Cocker continues gaining in substance and some height at 18 to 24 months, when it reaches maturity. The English Cocker Spaniel needs more exercise during the slow growth period to stimulate growth and keep its pace. The adolescent requires firm but kind education, perhaps more firm in males, which can be more independent during this phase. The character should be sweet and docile at every moment. The puppy’s hair changes between six and eight months, when the coat is no longer “plush” and is replaced by longer hair at the limbs, the body and the ears. During this period it should be brushed more often to avoid knotting and keep the hair and skin healthy.
The English Cocker Spaniel grows quickly until six months; on the following months it begins to shed its hair, and its general growth decreases, not reaching maturity before two years.
English Cocker Spaniel puppies should have clean eyes; checking the parents and puppy ensures a long life and good vision for your Cocker. 
The English Cocker Spaniel can live to 12 and even 15 years, although unfortunately it often becomes blind after 10. Eye problems are the most frequent in the breed. Progressive retinal atrophy, cataracts and glaucoma unfortunately happen often. An eye exam is a mandatory requirement. The swimming puppy (puppies that don’t develop proper limb musculature for which they can’t stand) also is reported in this breed. There is cryptorchidism, and – very rarely – a certain incidence to hermaphrodites. Veterinarians report distichiasis and kidney guests. Large dropping ears make the breed prone to ear infections, which can be minimized by controlling, cleaning and pulverizing the ears regularly.  A good diet and daily exercise is vital to guarantee adequate bone and muscle growth in this breed which matures slowly. Some Von Willebrand, a blood disease, and familiar nephropathy, a kidney disease, cases are reported.
