You know my head LGD would never kill anything but she patrols and will take off in a dead run at anything strange she sees that alone keeps the predators at bay, my Anatolian/great Pyrenees cross will kill if he could catch it but he is just a back up dog as far as predators, the rott will kill...
I don't kill anything but my dogs will if they feel the critter in entering the safe area that does not belong , it has been that way for 30 years here and it works for me.
This is 3 year old Gracie, she is my number 1 critter getter, i have lost count as to haw many snakes,coons and possums...
