lol! the growl makes you sound dangerous! you've probably seen photos of our German Shepard Jack because I keep including him in my posts? anyway he's the most gentle thing but if you start growling he doesn't like that and starts a low, gutteral, really mean sounding growl like he's getting ready to fight, he thinks he's being challenged and he doesn't like that, he's the Alpha dog around here. do you guys have a cat or dog or any pets? I don't know how common that is in England.
