Celebrated August 26th, National Dog Day recognizes the canine members of our families and communities.

Dogs have a long history of helping us humans; serving law enforcement officers in detecting bomb threats and drugs, locating victims in wreckage, and helping to find those people who've become lost.

In non-working roles, dogs and humans have bonded for thousands of years, starting as herding animals on farms and earning their keep in others ways.

Most recently, Comfort dogs were deployed to the site of the Sandy Hook school shooting, where the dogs helped school children and their parents cope with the loss.

The national observance of the day began in 2004 by Animal Behaviorist Colleen Paige to honor dogs of all breeds, pedigrees and roles.
