Exactely, I hope that CL actually confronted them, rather than posting pictures on here months later and proposing the idea to have dogs in general leashed on crown land etc.
Any hunter (regardless if they have a dog or not) should understand what that means when a dog is under control and that you don't need to have him on a leash!
There's nothing worse to have people within the hunting community demand restrictions, bans and more stupid rules that don't make any sense. A bit of common sense and enforcing just half the rules we have (e.g. running at large, harassing wildlife, etc.) should be more than enough!
