The breed was developed in Australia, although the ancestral types and breeds were from Great Britain. It is closely related to the Australian Terrier and the Yorkshire Terrier. The breed is called the Silky Terrier in North America, but is called the Australian Silky Terrier in its country of origin and in the rest of the world.

The Biewer Terrier (/ˌbiːvər ˈtɛriər/) is a toy dog of German descent that is the result of two Yorkshire Terriers with a recessive piebald gene breeding. It is usually kept as a companion animal or a show dog. The Biewer Terrier was recognized by the AKC in 2021. Since May 2024 the Biewer Terrier is also accepted by the (VDH) Verband für das Deutsche Hundewesen in Germany.[1][2]

The Yorkshire Terrier, also known as a Yorkie, is a British breed of toy dog of terrier type. It is among the smallest of the terriers and indeed of all dog breeds, with a weight of no more than 3.2 kg (7 lb).[1] It originated in the nineteenth century in the English county of Yorkshire, after which it is named.[2] The coat is tan on the head and dark steel-grey on the body; no other colour is accepted by either The Kennel Club or the Fédération Cynologique Internationale.[1][3]

The Society finch (Lonchura striata domestica), also known as the Bengali finch  or Bengalese finch, is a domesticated subspecies of estrildid finch. It became a popular cage and trade bird after appearing in European zoos in the 1860s through being imported from Japan, though it was domesticated in China. Coloration and behavior were modified through centuries of selection in Asia, then later in Europe and North America.[1]

The double-barred finch (Stizoptera bichenovii) is an estrildid finch found in dry savannah, tropical (lowland) dry grassland and shrubland habitats in northern and eastern Australia. It is sometimes referred to as Bicheno's finch or as the owl finch, the latter of which owing to the dark ring of feathers around the face. It is the only species placed in the genus Stizoptera .

The Australian zebra finch (Taeniopygia castanotis)[2] is the most common estrildid finch of Central Australia. It ranges over most of the continent, avoiding only the cool humid south and some areas of the tropical far north. The bird has been introduced to Puerto Rico and Portugal.[1] Due to the ease of keeping and breeding the zebra finch in captivity, it has become Australia's most widely studied bird; by 2010, it was the most studied captive model passerine species worldwide, by a considerable margin.[3]
