Tenterfield Terrier

Dog

Australian in development, the forebears of the Tenterfield Terrier accompanied Australia's first white settlers who sailed from Portsmouth in England's South. These small basically white dogs were vermin killers, surviving this harsh country without pampering. Today they are strong, hardy, active and agile, their smooth short coat making them 'easy care' family companions. Their unique feature is their naturally occurring bob tail which can come in any length.
