Australian Shepherd

Also called aussie.

Developed in the western United States despite the name. The merle coat and blue eyes are what people notice, and merle carries a genuine breeding hazard worth understanding.

What it looks like

Solidly built with a medium double coat, triangular ears set high and breaking forward, and frequently a naturally bobbed or docked tail. Often merle with blue or marbled eyes.

The characters that confirm it

  • A naturally bobbed or docked tail in many individuals — a Border Collie has a full tail.
  • Triangular drop ears breaking forward, not semi-erect.
  • Frequently merle: mottled patches of diluted colour over a solid base.
  • Heavier coat and squarer build than a Border Collie.

Temperament

High energy, strongly bonded, and prone to herding whatever is available including children.

Health

The MDR1 drug-sensitivity mutation is common and matters clinically. Collie eye anomaly and hereditary cataract have tests. Breeding two merles produces double-merle offspring with a high rate of deafness and blindness — this is entirely avoidable and is the reason merle-to-merle breeding is condemned.

Confused with

Full low-set tail with an upward swirl, lighter build, semi-erect ears.

Miniature American Shepherd

The same dog scaled down, now a separate breed.
