my mate had the same beardie/border 1/4 x 3 /4 grey of Hancock , it was big fawn dog 27in and strong , was good on hares- day, and good in the lamp rabbits. But his dog was the same type temp, was ok with dogs as long as were ok with him, but fook me on foxes he would smash them easy, he killed 2 in a morning and killed another 1 same night. I wonder if its the beardie puts that bit of fire in them , as borders seem not have as much about them.?
