The Unbreakable Bond Between Dogs and Humans

As many pet-owners will tell you, dogs are more than just lovable balls of fur. Humans are indebted to them and the services they provide whether herding sheep, assisting those with special needs, or working on police teams. Without question, the dog's keen sense of smell has a lot to do with our dependence on them. Dogs can user their sense of smell to detect everything from drugs to pirated DVDs to even cancer cells. Some studies suggest that dogs can even "sniff out" human emotion. According to these studies, dogs can read and understand even the most subtle body language, often discerning what we feel before we do. With all they do for us, and often selflessly so, dogs have rightfully earned their title as "man's best friend."
