The Field Spaniel is a medium size, well-balanced beauty and utility combined. It has a noble appearance and boasts of a handsome glossy coat. Its almond-shaped eyes, dark and hazel in colour and set moderately wide reveal its intelligence and gentle albeit grave expression. It has pendulous ears that are set low, well feathered and hang close to its head. The Field Spaniel has a lean muzzle and a strong jaw. Neck is long, strong, muscular and is slightly arched and well set into the shoulders, sloping smoothly into the withers. It has a well-muscled back that is firm and strong. Field Spaniels also have well-sprung ribs that curve gently into a firm loin.
The breed sports a moderately long silky single coat, meaning there is no undercoat. Because of its glossy characteristic, its coat is extremely weatherproof. Feathering appears on the chest, belly, ears, and on the back of the legs but never from their hocks to the ground. Although not as dense as that of the Cocker Spaniel, the Field Spaniel's coat will need regular brushing and occasional trimming.
The coat comes in various colours such as black, liver or roan or any of these colours with tan points. Their nails should be regularly trimmed to avoid cracking. Ears must be cleaned on a regular basis, paying particular attention to any debris or excessive wax build-up that can lead to infection. As well, oral care is important to prevent gum disease and bad breath.
