Cocker Spaniels have charmingly square muzzles with well-developed skulls which are nicely proportioned, giving them their unique and endearing looks. Their eyes are typically dark or brown in colour and nicely rounded, not protruded at all. Dogs with liver or liver roan coats as well as liver and white dogs have hazel coloured eyes that blend in well with their colouring which is totally acceptable as a breed standard. Cockers are considered to have an intelligent look in their eyes, gentle yet always very alert.
