Australian Shepherd Breed Standard
INTRODUCTION: First and foremost, the Australian Shepherd is a true working stockdog, and anything that detracts from his usefulness as such is undesirable. The most important breed characteristics are overall moderation in size and bone, balance with correct proportions, and sound movement.
GENERAL APPEARANCE: The Australian Shepherd is a well-balanced dog of medium size and bone. He is attentive and animated, showing strength and stamina combined with unusual agility. Slightly longer than tall, he has a coat of moderate length and coarseness with coloring that offers variety and individuality in each specimen. An identifying characteristic is his natural or docked bobtail. In each sex, masculinity or femininity is well defined.
