Like other spaniels, the long floppy ears predispose English Cockers to ear infections. The breed is also prone to progressive retinal atrophy (PRA), which is inherited and can be screened with a DNA test, and hip dysplasia.
A quality diet matched to activity level; working-line English Cockers need considerably more calories than companion-line dogs living a lower-activity lifestyle.
The medium-length silky coat needs regular brushing, with trimming to manage the feathering without interfering with field work if the dog is active outdoors.
Easily trained and willing to work — English Cockers are excellent companions and capable field dogs alike, and generally respond best to positive, consistent handling.
The English Cocker Spaniel shares direct ancestry with the American Cocker Spaniel, both descending from the same English land spaniels used to flush woodcock — the two were one breed until 1946, when the AKC formally split them after American breeders had spent decades selecting for a smaller, more domed-headed dog. Outside the US, this type is simply called the "Cocker Spaniel," while the American variety is called out separately.
Known as the "Merry Spaniel" for a near-constantly wagging tail, English Cockers retain more of the original working-spaniel build and drive than their American cousins, with a gait built for power and endurance in dense hunting cover.
