National Mutt Day was founded in 2005 by animal welfare advocate Colleen Paige to support the many mixed-breed dogs waiting in shelters. Observed twice a year, on July 31 and December 2, the day raises awareness about adoption and challenges outdated ideas about mutts being less desirable than purebred dogs.
Mixed-breed dogs make up about 80% of shelter population and often face higher euthanasia rates, and this observance highlights their individuality, strong health, and the joy they bring when given a permanent home.
