What is white terrier extinct?

The white terrier breed is not extinct, but some sub-breeds have become extinct over time.

One such sub-breed is the English White Terrier, which was popular in the late 19th century. However, due to excessive breeding and inbreeding, the breed suffered from various health issues. As a result, it became extinct by the early 20th century.

Another extinct sub-breed of white terrier is the Paisley Terrier, which was similar to the Scottish Terrier but with longer hair. It was popular in the mid-19th century but became extinct by the early 20th century.

There are still many white terrier breeds that exist today, including the West Highland White Terrier, the Jack Russell Terrier, and the American Eskimo Dog. These breeds have been bred to eliminate health issues and avoid the fate of extinction.
