During the 1920s, Leon Verrier's dogs dominated the exhibitions and were the type most sought after by the newly formed association for the breed. His own kennels were wiped out following World War I; however, he remained a strong influence on the breed as chairman of the breed's club, and continued to strengthen the Norman character of the breed.
Following World War II, breed numbers depleted and very few pure specimens of the Norman Artesien Basset remained. However, several dedicated breeders worked hard to save the Norman Artesien Basset from extinction. The Norman Artesien Basset was officially recognised by the United Kennel Club in 1995.
