History of Working Dogs - for nearly 15,000 years dogs have lived with and served humankind as companions, hunters, shepherds and most recently detectives. Much of the relationship has been forged in warfare with dogs serving as sentries, guards, mascots, messengers, draft animals and scouts for the Egyptians, Greeks, Assyrians, and the Persians armies. In fact, the Roman legions trained entire formations of armoured attack dogs which were deployed against enemy armies.
