Gnash iv never really thought much of them but last year I was at my bosses sisters house, her and her husband have silly money, and he paid I'm sure it was 10k for a young dog trained to protect his wife and kids, and the dog took orders from him and the nanny, he always tests the dog every time his best mate goes round iv not seen it happen but boss did once n said it was a shame for the guy lol, dog goes all over the place with them and keeps a close eye on the kids at all times soon as anyone goes near he's right on it waiting for a command I think
