For me it is the Jack Russell terrier. I have always been of he opinion that working terriers are a rather unique type of dog. Small in size (from necessity) but never stature. Hunt like hounds but game . As unique as all working bred terriers are I find the Jack Russell the most enigmatic. What exactly are they? What defines them?. Well that's easy now, if they are not recognised by the KC as a Parson or a Jack Russell then they are just mongrels. I can live with that. The Jack Russells themselves don't really give a shit.
