I must say I had never heard of tenterfield terrier before either
Thank you for sharing with us and welcome to Pet Talk.

This is something I quoted from
http://www.dogbreedinfo.com/tenterfieldterrier.htm

The Tenterfield Terrier was developed by crossing the Standard Fox Terriers (Smooth) with the Manchester Black and Tan or English Toy Terriers (Black & Tan). At a later stage the Whippet was introduced. At one stage Chihuahua was used but any outcrossing to other breeds is now quite forbidden. Though the Tenterfield Terrier originated in England in the 1800's, it was developed into the type it is today in Australia, making it one of only a few truly Australian bred dogs. It is found nowhere else in the world. The breed is sometimes confused with the Jack Russell, However they are some quite different.
