The poodle is an active, intelligent and elegant dog, squarely built. To ensure the desirable squarely built appearance, the length of body measured from the breastbone to the point of the rump approximates the height from the highest point of the shoulders to the ground. The eyes should be very dark, oval in shape, and have an alert and intelligent expression. The ears should fold over close to the head, set at, or slightly below, eye level. The coat should be of naturally curly texture, dense throughout, although most AKC-registered show dogs have a lion-cut or other, similarly shaven look. The sizes of the official AKC-recognized Poodle breeds are determined by height, not by weight.
