Oh, Lord; Jack Russels. My older sister got talked into taking a young Jack Russel from someone whose kid turned out to be allergic to it. It's an outrageous dog option for an older lady, in a small house, with no knack for teaching obedience. At least it has mellowed significantly after a couple of years. Dumb, it isn't. But when I first encountered it, I was about ready to write it off as totally "nucking futs". But, yes, so darn much fun so much of the time.
