|"Best in Show" from David McCandless' fascinating new book Knowledge is Beautiful, ranks 87 dog breeds and compares those rankings to the actual popularity of the breeds in the US.
The ranking is based on a number of factors: trainability, life expectancy, lifetime cost (including the price of food and grooming), and suitability for children, among others.
