Albert Frederick Hochwalt, Dogs as home companions (1922)
“ Every dog recognizes his friends among humankind with one glance at a person’s face. The dog is a better student of human nature than any other animal—biped or otherwise—and the dog that shuns one person and loves another knows from instinct and perception how to distribute his likes and dislikes. Therefore, those who see nothing but viciousness in the canine race have no one but themselves to blame; the dog knows his enemies at sight. ”
