Australian Cattle Dog
The compact but muscular Australian Cattle Dog, also called Blue Heeler or Queensland Heeler, is related to Australia’s famous wild dog, the Dingo. These resilient herders are intelligent enough to routinely outsmart their owners, according to the AKC.
Standing between 17 to 20 inches at the shoulder, the Australian Cattle Dog is a sturdy, hard-muscled herder of strength and agility. The ACD is born with a white coat that turns blue-gray or red. Both coat varieties feature distinctive mottling or specking patterns. ACDs have immense work drive and excel at hunting, chasing, and, of course, moving livestock. Their boundless energy and supple gait make them excellent running partners.
ACDs are true-blue loyal, famously smart, ever alert, and wary of strangers. If an ACD isn’t challenged, he easily becomes bored and gets into mischief. It is recommended that ACD owners participate with their dog in some work, sport, or regular exercise to keep him mentally and physically fit, according to the AKC.
