These Photos of Adorable Mutts Will Have You Running to Fill Out Adoption Papers

National Mixed Breed Dog Day is December 2nd (and July 31st) and we are celebrating with photos of the most adorable mutts we could find. These pups come from all around the nation and are mostly available for adoption. It's important that we remember to adopt pups from local shelters whenever possible. 670,000 shelter dogs are euthanized every year and a big percentage of those pups are mixed breed. Organizations like the ASPCA and The Sato Project are committed to helping these cute doggies. Check out some of the most lovable best friends we could find.
