The American Society for the Prevention of Cruelty to Animals (ASPCA) and the American Humane Association (AHA) have deemed the month of October National Adopt a Shelter Dog Month and Adopt a Dog Month, respectively.
Ideally, the best way to celebrate would be to adopt a shelter dog, however, if you are unable to do so, spread the word. Post it on Twitter, Facebook, and any other social media you can think of using #AdoptAShelterDogMonth.
