Australian Terriers were developed in 1800s Australia from rough-coated British terriers to kill rats and snakes and guard the homestead. They're small but long-bodied, 10 to 11 inches tall and roughly 14 to 20 pounds, with erect ears, a harsh blue-and-tan, sandy or red coat and a soft, silky topknot. The AKC recognized the breed in 1960, and it was the first native Australian breed to gain recognition.
Many Aussies are confident, affectionate and more tenacious than their size suggests. They tend to bond closely, bark at anything unusual and chase small animals with real conviction, which is worth remembering on Chicago sidewalks full of squirrels. Dogs vary, but most do best with adopters who enjoy short, game-like training and can offer daily activity on a leash or inside secure fencing.
