In 2004, author and pet expert Colleen Paige founded National Dog Day. It's meant to galvanize the public to recognize the number of dogs that need to be rescued each year and "encourage dog ownership of all breeds, mixed and pure". The Humane Society of the United States says the U.S. has decreased the number of dogs and cats euthanized from 12-20 million in 1970 to 3.4 million in 2010. But only 30% of pets in homes come from shelters and rescues.
