Many people might pity the dogs, who obviously don't have much choice in the matter. They don't join ROTC or go to a recruiting office. However, I've always believed that dogs who have a purpose thrive.
Military working dogs and their handlers can be together 24/7 while deployed. More often than not, the canine warriors eat and work and socialize with their handlers. They sleep in or near their handlers' cots. Some dogs crawl right into their sleeping bags.
