Danny was a small wire-haired terrier, his fur short like a wire brush. He was very smart for a small dog. Whenever Denis his master would talk to him he would tilt his head to one side, lift his eyes and look at Denis intelligently. Denis was 10 years old. He had brown hair and brown eyes. Both Danny and Denis were very kind and well-liked in the neighbourhood.

One day a stray mongrel dog came into the neighbourhood, he had a mean look on his face.  He walked side to side on the sidewalk sniffing at the ground.
