The term ‘three dog night’ (attributed to Australian Aborigines) came about because on especially cold nights these nomadic people needed three dogs (dingoes, actually) to keep from freezing.
Dingoes have features that resemble both dogs and wolves, although dingoes have a longer muzzle, longer canine teeth and a flatter skull.
The dingo (Canis lupus dingo) is a free-ranging/wild dog found mainly in Australia, as well as Southeast Asia, where it is said to have originated. It is currently classified as a subspecies of the grey wolf, Canis lupus.
Australian dingoes – which were introduced to Australia about 3,000 years ago – may well be extinct within the next 50 years, unless steps are taken to prevent them from crossbreeding with domestic dogs.
