As their name suggests, red heelers -- hearty herding dogs -- are trained to nip at the heels of animals to drive them forward. They're hearty herding dogs. Officially known as the Australian cattle dog, these jovial canines are a medium-size breed. Australian cattle dogs come in red and blue coat varieties. Their medium build and desire to please makes them appealing pets, but they require plenty of stimulation to stave off boredom.
The Australian cattle dog is one of the most tenacious herding breeds in the world. Cattleman George Hall, widely considered to be the founder of the breed, began a cattle operation in the early 1800s. George and his son Thomas drove cattle thousands of kilometers to Sydney and needed a dog to help push cattle through dense underbrush. Local droving dogs, imported from England, were not hearty enough to withstand the harsh conditions of the Outback; this problem was solved when the Halls crossed their dogs with native dingoes that Thomas had tamed. These dogs, known as Hall's heelers, attracted a large following but were kept within the family until an estate auction following Thomas’ death in 1870. Robert Kaleski purchased a number of these dogs and eventually drew up a standard that would present them to the world as the Australian cattle dog.
Red heelers should stand between 17 and 20 inches tall at the top of the withers. Average weight for these cheerful red dogs ranges between 35 and 45 pounds. Male red heelers tend to weigh more thanks to their denser bone structure. A properly built red heeler should be slightly longer than he is tall. He may or may not have a full tail.
Female red heelers gravitate toward the smaller ends of the height and weight scales; they're generally more petite than their male counterparts. Females should retain the 10-to-9 length-to-height ratio but should have smaller bone structure and slightly more refined features than males. Despite their smaller stature, female red heelers are just as determined and hard-working as male dogs.
The red heeler’s size makes him a perfect droving dog. By definition, a drover pushes livestock forward and keeps a drove moving in the right direction. However, cattle can be stubborn, and they kick. The heeler’s instinctive nipping of the heels of lazy cattle would endanger a larger dog -- but flying hooves sail over the heads of these dogs, saving them from doom. The red heeler’s size also gives him an edge in competitions such as agility, allowing the dog to clear hurdles and sneak through tunnels that might be more difficult for taller dogs.
