My Ridgie will play games all day with someone she knows...God help those who she doesn't!! She was trained, by me to be a "face dog" and that's what she aims at....a 50 kg dog attached to your face isn't something to smile about (pun intended). It's also legal for a citizen to own a gun (pistol, rifle, shotgun) for the purpose of defending his property (must be licenced, of course) and if anyone gets shot, inside your boundary....tough sh!t!! Might explain why home invasions and robberies numbered about 10, for the whole country last year!! I own a Browning Hi Power, 9mm pistol which I'm very experienced and proficient with, but I've not had to use it in anger over here...my dog is the best deterrent!!
