The Sussex Spaniel's Origins and History Source: www.kennels.co.uk/Gundogs/SussexSpaniel.html Country/Region of Origin: England Original purpose: hunting Name: Derived from where it was developed, Sussex. Historical notes: Sussex Spaniel dogs were developed by Mr. Fuller of Brightling in the early 1800's and the process took decades. They had a low point during the World Wars when there were only 5 known dogs left. A lot of breeds in Europe nearly died off because economics and opinion were not conducive to devoting time and resources to maintaining a kennel of purebreds. During the 1950's, devoted efforts by Mrs. Joy Freer and other like-minded fanciers brought the Sussex Spaniels back from the brink of extinction.
