[5] In the late 1960s and throughout the 1970s, Brian Plummer worked as a somewhat reluctant teacher of several schools throughout southern Yorkshire and the Midlands.

The Beagle introduced to Plummer's lines in the 1960s was out of Catherine Sutton's Rossut show-bred strain that originated from U.S. imports, brought to the U.K. to tidy up British exhibits.

Further additions included a Jack Russell terrier known as Errol Forsyth's Pip, Alan Thomas's Hamish, and Laddie from the Chiddingfold and Leconfield foxhound kennels.

Performance as an earth dog was and is an essential prerequisite of most, if not all terrier breeds and Plummers are no exception to this rule.

[citation needed] In 1985, he suffered a near-fatal heart attack which resulted in the dispersal of his substantial pack of terriers to friends.

Plummer opted for the latter, and by the late 1990s decided that the breed needed a wider gene pool in order to reach its maximum potential.

]; some are found in the beating line on local shoots; occasionally they are used to ground but undoubtedly they are most commonly used in a pack hunting rats.

Terriers that do not possess collared or caped markings are labelled shattered, they are perfectly fine as workers, companions but are not classed as good examples of the breed.

The ears fold over like most terriers, and the nose and eye are typically black, and the jaw has a good scissors bite.
