The tail may measure no more than ten centimetres, naturally: the FCI standard requires an undocked stumpy tail and treats a docked tail as a disqualifying fault. Behind that short tail is a tough, tireless cattle dog from the Australian outback.

Smithfields, dingoes and a merle collie
According to the standard, the breed was deliberately developed for cattle work in the early 19th century. One account names Thomas Simpson Hall, who crossed northern English sheepdogs called Smithfields with dingoes around 1830. Another describes a drover named Timmins mating a Smithfield female with a dingo. The red, stumpy-tailed descendants, Timmins Biters, were too rough with cattle; a smooth-haired blue-merle collie then helped produce an all-round worker. The breed has carried its current name since 2001.
What provisional recognition means
The FCI provisionally recognised the breed on 06.07.2005, and that status remains. Until definitive recognition, the FCI says such breeds cannot receive a CACIB, the qualifying award towards an international beauty championship. They can still become World or Section Winners, and their pedigrees carry the FCI logo.
Related to the Cattle Dog, but different
The Australian Cattle Dog also has dingoes and blue-merle smooth-haired collies among its ancestors, according to its own standard. The Stumpy is squarer in build, never has tan markings and is born without a long tail.
Loyal to family, wary of strangers
Loyal, courageous and affectionate, attentive, watchful and obedient, yet suspicious of strangers: that is the standard’s description. Calm, early encounters with people and dogs help the Stumpy remain composed. The name Timmins Biters recalls that cattle dogs also work with their teeth: puppies should never learn that nipping calves is a game.
Work for mind and legs, little coat maintenance
Bred for long, hard working days, the Stumpy needs herding practice, treibball, tracking or obedience, plus distance on hikes. The short, dense coat, meanwhile, needs only weekly brushing.
Deafness is the major health concern
An Australian study assessed 315 Stumpies using BAER hearing tests: 56 dogs (17.8 percent) were deaf, including 17 in both ears. Deafness is inherited recessively, and red dogs were affected 1.8 times as often as blue dogs (Sommerlad et al. 2010). A KLF7 gene variant is a possible cause (Xu et al. 2021). Ask the breeder for BAER results for the puppy and parents. We found no reliable lifespan study.
Who will enjoy a Stumpy?
People experienced with cattle or sheepdogs who spend plenty of time outdoors and want to work together, ideally with livestock or dog sports. Less suitable for constantly changing visitors, city flats or small children the dog may try to herd. Finding a puppy requires patience: even the standard mentions how few of these dogs have ever entered a studbook.
The breed quiz shows whether this working dog suits you; our book “Which Dog REALLY Suits You?” (book in German) explores the question more thoroughly. For the start of puppyhood, there is the free Puppy Starter Pack. Bring your Stumpy to the wall as a dog portrait from your own photo or a magazine-cover canvas.
