My dads dog,,, DON.
5/8 collie in the mix, and he's no thinker... In fact total opposite, he was a kamakazee type dog rabbiting etc, full on, no reverse. Took everything aswell, and done everything, from ratting, ferreting, lamping, beating, digging, etc etc,,,, The Dog had a broken leg has a pup, and lost his eye to a kick from a beast later in his career which stopped the lamping had it made him blind in one eye...he's still doing bits on the fells and mooching about but not as much nowadays.
