The Stumpy Tail Cattle Dog was developed in Australia in the mid-1800's. The Smithfield, a bob-tailed British droving dog, was crossed with the dingo and later with a blue merle Smooth Collie. The breed was recognized by the Australian National Kennel Council in 1988. The Stumpy Tail Cattle Dog is used for working cattle and it also competes in show and obedience trials.
