The Denaturing of Dogs

"Through selective breeding, experts have been meeting the demands for smaller dogs, dogs which eat less and can be kept more economically; dogs which need less exercise, and therefore retain better health in cramped quarters. The motor age has restricted the exercise of dogs even more than that of men. It has created a need for breeds which remain in good physical condition when they are walked only on a leash, or at best in close company of their owners, instead of being allowed to run free. Thousands of motorists want dogs adapted to riding in cars instead of to loping for miles alongside horse-drawn coaches."
