Unkelbach's eyes nearly pop out of his head at the thought of the ""7 billion doggy dollars"" spent every year by indulgent pet owners, and he appeals not to our love of dogs (if you don't like them, ""get busy and learn to like them"") but to our avarice. Actually, he offers little more than an outline of promising possibilities and many of the less obvious suggestions -- photographing dogs, writing a magazine column, selling aprons and other accessories at pet shows, even starting a dog cemetery on your own property (!) -- are improbable at the very least. Unkelbach does tell the rather discouraging dollars and cents truth about dog breeding and this chapter might give even grown-up owners a realistic assessment of its difficulties. However one suspects that most of this hard sell advice is merely another way of making the ""dog game"" pay off -- in author's royalties.
