Australian Cattle Dogs were developed in nineteenth-century Australia to drive cattle over long distances, and they still carry that working mindset. They're medium-sized and muscular, usually 35 to 50 pounds, with a hard, weather-resistant double coat in blue or red speckle. That short coat sheds water well, which helps in a rainy place like Wilmington, and it stays tidy with a weekly brushing.
Heelers tend to bond closely with one person and stay reserved with strangers. They learn fast and can outsmart a casual owner, so consistent, reward-based training pays off. Nipping and chasing are common herding habits, and early socialization helps. A Heeler's stamina often outlasts its owner's, so planning honestly for daily exercise matters more than yard size.
