How true are the stories about mad dog? Most of the stories are not ture at all. A mad dog is very ill. Not one "mad" dog in thousands is really mad. Put a looking glass in front of your dog. He may not look at it twice. His eyes may tell him there is another dog facing him,but his nose tells him there is not. He can smell better than he can see,so he will believe his nose rather than his eyes. Your dog will know you,no matter how you change your looks. He knows your scent.
