The fact that dogs are not people means you don't have as much response to the particulars.

Sense of smell, of course, is only one of those dog qualities that can't be replicated or improved upon. I've been researching dogs in warfare for my book about 'Rin Tin Tin,' and I've read many accounts of their heroics: carrying messages through battle, alerting troops to enemy planes, and even parachuting behind enemy lines.

Dogs really are perfect soldiers. They are brave and smart; they can smell through walls, see in the dark, and eat Army rations without complaint.

Dog parks are more cliquish than any other human gathering with the possible exception of seventh grade. Deal with it.
