During which period did the Welsh Terrier reportedly dwindle to dangerously low numbers, nearing extinction?

Answer

Mid-to-late nineteenth century

Despite its established utility as a working dog, the advent of modernized farming techniques reduced the traditional need for vermin control, placing the Welsh Terrier in jeopardy. During the mid-to-late nineteenth century, the breed's numbers declined drastically, reaching levels so low that the breed was considered to be bordering on extinction. This crisis prompted dedicated enthusiasts to intervene immediately with conservation efforts to save this distinct national breed from disappearing entirely.
