The Field Spaniel is affectionate, docile and sensitive, and does not respond well to harsh handling. It is energetic and playful outdoors, tends to bond closely with its household and is often reserved with strangers at first. It remains uncommon, even in its home country.
Today it is a sturdy, noble-looking spaniel, somewhat longer than it is tall, with a long head, a gentle expression and long, low-set ears. The single coat is glossy and flat or slightly wavy, with feathering on the chest, belly, legs and ears. Solid black or liver is usual, sometimes with tan markings, and roans occur.
The Field Spaniel developed alongside the Cocker Spaniel, and for a time the two were separated largely by weight, with the heavier dogs shown as Field Spaniels. In the late nineteenth century, breeders including Phineas Bullock crossed in Sussex Spaniel blood and selected for an ever longer, lower body. Critics mocked the resulting dogs as exaggerated and unfit for work. Breeders later worked back towards a balanced, practical build, and after the breed nearly disappeared in the mid-twentieth century it was revived. It was developed to hunt close to the gun, flushing game from thick cover and retrieving on land and from water.
