Australian Cattle Dogs, also called Blue Heelers or Queensland Heelers, were developed in nineteenth-century Australia to drive cattle over long distances in heat and dust. Settlers crossed collie-type herding dogs with dingoes to produce a tough, quiet worker that nips at heels to move stock. Heelers are compact and muscular, usually 35 to 50 pounds, with a short, weatherproof double coat in blue or red speckle.
Heelers tend to be loyal, alert and clever, often bonding closely with one person and staying wary of strangers. Their urge to chase and herd can show up as nipping at kids, bikes or other pets, which matters on shared Lincoln trails. With training and a real outlet for their drive, many are devoted, hardy companions that live 12 to 16 years. The coat blows once or twice a year.
