Australian Cattle Dogs, also called Blue Heelers or Queensland Heelers, were developed in nineteenth-century Australia to move cattle across long, hot distances. The result is a compact, muscular dog of about 35 to 50 pounds with a weatherproof double coat in blue or red speckle. The dense undercoat sheds heavily once or twice a year.
Heelers are sharp, loyal and often attached to one person, and many stay wary of strangers. Their herding drive can show up as nipping at heels, chasing bikes or bossing other pets. In Fargo, that means a household that can offer long outings, training and puzzle work in every season, including the long winter. Dogs vary, and plenty of Heelers are calmer than the stereotype.
