Coat and looks how to spot one

medium-length double coat

A weatherproof double coat of medium length that can be straight or gently wavy. The hair stays short and smooth on the head and fronts of the legs, with light feathering on the backs of the forelegs and on the trousers. The tail may be docked or a natural bobtail.314

Coloursblackblue merlered (liver)red merleany of these with white and/or tan markings314

Personality what they are like

A bright, eager working dog with real herding and watchdog instincts packed into a compact frame. It tends to be polite but reserved with people it does not know, and warm, playful and protective with its own family. It is easy to train and thrives when given a job.345

Daily activity how busy a day looks

High. This is an energetic herding breed that needs daily exercise plus mental work; it shines in herding, agility, obedience, flyball and canine freestyle.25

Grooming and care the hands-on bits

Regular brushing keeps the medium double coat tidy and removes loose undercoat; the feathering on legs and trousers benefits from a comb-through.31

Home where they are happiest

Suits an active home with space to move and daily outings; its small size makes it easy to travel with.15

Company who they like around

Very people-focused and bonds closely with its family; early, friendly meetings with strangers help its natural reserve stay relaxed.31

The story where it all began

Breeders in California began selecting the smallest Australian Shepherds in the late 1960s, aiming for a handy-sized herder; the size was steady by the mid-1970s and the first dogs were registered in 1980. Horse people took to the breed as a travelling companion on the show circuit. It was first known as the Miniature Australian Shepherd before being renamed, and it later gained AKC, UKC and FCI recognition.12
