The Australian Kelpie is a lean, prick-eared herding dog developed in Australia in the 1870s from Scottish working collies to move sheep across hot, open country. Stamina and toughness are the breed's trademarks. The short, weather-resistant double coat sheds moderately all year, with heavier spells in spring and fall. Most Kelpies weigh 25 to 45 pounds, so they're medium dogs that move like athletes.
Many Kelpies are alert, quick to learn and devoted to their people. The same drive can turn into nipping at heels, chasing bikes or barking when a dog is bored. Adopters should plan real work for the dog: long trail runs, fetch in a fenced park, training games and puzzle toys. Kelpies vary, and working-line dogs often have more drive than show-line dogs.
