i have a mean german shepherd great with the family but bugger if i would wanna break in ,black face ,when we lived in town we use to leave the roller door up enough for him to get his head under ,many people crossed over the other side of the road in a hurry,now where out town you can,t get near the place without the dog telling you about it,living in far north queensland it,s the best defence ,a friend of mine had his r1 yamaha stolen,thief handed over his license for id grabbed his helmet and rode off ,the license belonged to the thief ,bike has not been seen since and the address on the license was false
