Why are Sussex Spaniels so rare?

Sussex Spaniels are rare for a few reasons. After their popularity in the late 19th and early 20th centuries, their numbers began to decline, particularly after World War II. Changes in hunting practices, a shift in public interest toward other breeds, and the rise of more popular Spaniels contributed to their reduced numbers. Dedicated breeders have worked to preserve the breed, but the Sussex Spaniel remains relatively uncommon.
