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]
