The Australian Terrier is a breed originally from Australia, as you probably guessed from the name. However, despite the fact that the breed is considered Australian, it descended from British terriers, which were imported by settlers. In the course of the formation of the breed, various terriers interbred with each other until they turned out to be small, but very funny and in many ways useful companions.
The first European settlers in Australia lived in rather harsh conditions, they had to start everything literally from scratch, in a new climate, and in a completely different environment from their own. Therefore, the requirements for dogs that were supposed to share with them all the hardships of this life also corresponded.
He also served as a hunter for rodents and small animals, and these instincts in the breed are still strong.
Surprisingly, not the Aussie (Australian Shepherd), but the Australian Terrier, this is the first native breed to receive official recognition in Australia.
