The ETS is a square, snub-nosed toy weighing no more than 14 pounds. The large domed head—with its long and lush ears, dark melting eyes, and chubby cheeks—is a famous breed trait. The profuse coat comes in four varieties, each with its own proper name: red and white (Blenheim); black and tan (King Charles); white, black, and tan (Prince Charles); and a solid red (Ruby). Blenheims often have a red mark, the “Blenheim Spot,” on top of the head. The ETS, like many toy breeds kept by royals, came to assume the personalities of their aristocratic owners. They can be proud and willful, and extremely discriminating in their choice of friends. With their favored humans, they are affectionate at home and exuberant and curious at play (akc.org).
