Neither did we.  National Dog Day was created by the Animal Miracle Network, and it's celebrated every year on August 26th to acknowledge family dogs, and dogs that work selflessly every day to save lives, keep us safe and bring comfort.

It also works to focus public attention on the number of dogs that need to be rescued each year.

Founded in 2004 by pet lifestyle expert and author Colleen Paige, National Dog Day was created to honor dogs more than we currently do, and show our appreciation 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.

On its website, the Animal Miracle Network says "dogs put their lives on the line every day - for their law enforcement partner, for their blind companion, for a child who is disabled, and for our safety by detecting bombs and drugs and pulling victims of tragedy from wreckage.

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”.

It was Mark Twain who wrote in his novel Pudd'nhead Wilson that "If you pick up a starving dog and make him prosperous, he will not bite you.  This is the principal difference between a dog and a man."

Twain also wrote, in a letter to a friend, "The dog is a gentleman;  I hope to go to his heaven, not man's."

Twain would no doubt say that every day should be National Dog Day.
