National Mutt Day is celebrated on July 31 and focuses on promoting mixed breed dogs, often referred to as mutts. Founded by animal welfare advocate Colleen Paige, the day aims to raise awareness about the challenges faced by these dogs, who are frequently abandoned. Observers of National Mutt Day engage in various activities, such as treating their mutts to special toys or treats, scheduling veterinary visits, and considering adopting a mutt from local animal shelters. The day also encourages volunteering at shelters to help homeless animals find loving homes. In addition to celebrating the unique qualities of mutts, the day serves as a reminder of their value as pets, despite any negative connotations associated with the term "mutt."
