National Dog Day was created to help the public recognize the number of dogs that need to be rescued each year, and acknowledges family dogs and dogs that work selflessly each day to save lives, keep us safe and bring comfort. Dogs put their lives on the line every day - for their law enforcement partner, for their blind companion, for a child who is disabled, for our freedom and safety by detecting bombs and drugs and pulling victims of tragedy from wreckage. Founded in 2004 by pet lifestyle expert and author Colleen Paige, National Dog Day was created to honor dogs more than we currently do, to give them "a day", to show deep appreciation for our long connection to each other - for their endearing patience, unquestioning loyalty, for their work, their capacity for love and their ability to impact our lives everyday in the most miraculous ways. National Dog Day wishes to encourage dog ownership of all breeds, mixed and pure - and embraces the opportunity for all dogs to live a happy, safe and ”abuse-free life”."
