Dogs are the best! We have 2,an australian sheppard that will run right up to people she knows,or doesnt know,all the while emmiting the nastiest snarl/bark Ive heard.But she is not the one to worry about.About 20 feet behind her,edgeing her way up in a sideways,head down creep,is the black/silver siberian husky,not makeing a sound,but with neck hair raised straight up!Now,she wouldnt bite a person,even if they bit her first,but she is one scary looking canine!The two of them developed this method of attack for coons ,skunks porkys and cats,which the husky DOES kill immeadiately upon engagement!
