The miniature australian shepherd was developed by breeding smaller Australian Shepherds for the desired size. The breed is rapidly increasing in popularity among those interested in a compact dog with a strong dog work ethic. They are especially popular in dog agility, and do well in other dog sports including herding, obedience, disc dog, flyball and many other activities.
The preferred height of the toy australian shepherd ranges from 14 to 18 inches (35 to 46 cm) at the withers and the weight is typically between 17 and 30 pounds (9 to 14 kg). Coat colors are blue merle, red merle, black, merle, and red, all with or without copper as well as with or without white trim. Eyes may be any combination of brown, amber, hazel, blue, or marbled. Some of these dog have eyes that are two different colors or may be marbled or swirled. Some may have a natural bobtail or the tail may be docked.
