My polecat dog can't fit down holes, he is soft as anything though he plays like a puppy at 3 years old. I had to hand rear him as the mother died when the kits were a week old, i gave all them away except for him and his sister, he was on my mates farm and got out 1 night and killed the chickens. He also tried for the geese another time but my mate got him before he could grab 1 of them
