Taiwan Dog

Also known as the Taiwan Dog, the Formosan Mountain Dog is a medium sized breed that is closely related to the wild Dingo. These dogs have a long history in East Asia, where they were used as hunting dogs, guard dogs, watchdogs, and companion dogs. The Formosan Mountain dog is very rare and exceptionally valuable. UK owners will have a tough time finding a specialist breeder. And even if they do, they should expect to pay thousands of pounds for these highly-prized dogs.

Origins and history

The Formosan Mountain Dog is a descendent of the South Asian Pariah Dogs. These semi-wild dogs would live on the outskirts of human settlements, scavenging for scraps and hunting small vermin. After the Dutch established a base in the region, they began crossing their own hunting breeds with the Pariah Dogs. The result of that pairing was the Formosan Mountain Dog. Since then, it’s been mixed with both Japanese and Western Hunting dogs, producing a wide range of crossbreeds. Purebred Formosans became very rare. They were also used for dog meat after Taiwan came under Chinese control. As a result, their numbers were very close to extinction levels and still remain a cause for concern. Researchers from Taiwan’s top universities are working on programmes to save this ancient breed.

Good to know

Purebred Formosan Mountain dogs are very rare. As a result, puppies can change hands for thousands of pounds. 

Any breeders offering “cheap” Formosans should be avoided. The puppies are likely to have been born with serious genetic disorders.

Formosan Mountain Dogs produce huge litters. It’s not uncommon for them to produce as many as 12 puppies.
