Why should they get permission? I got a dog knowing I would have to poach - stopped me fighting,drinking, taking drugs, selling drugs and much other stuff. I learnt a lot by not having permission for the first several years, stuff I would have never learnt if I had permission. Whether you agree or not it was that poaching that taught me field craft as poaching causes you to be quiet, careful with the lamp and careful whom you take to land you have found. I respect my dogs, quarry and the land in my opinion more because I started out poaching
