No Pet Store Puppies Day is observed worldwide every July 21. This awareness campaign aims to highlight the cruel conditions of puppy mills and encourages individuals to adopt puppies from shelters or purchase them from ethical breeders instead of buying from pet stores. Puppy mills, which became widespread after World War II, prioritize quantity over quality, often keeping dogs in unsanitary and overcrowded conditions. The campaign is actively promoted by the American Society for Prevention of Cruelty to Animals (ASPCA), which seeks to protect animals from cruelty in the United States. Observers are encouraged to adopt from local shelters, research responsible breeders, and avoid supporting pet stores that sell puppies from mills. Additional ways to participate include donating to animal welfare organizations, volunteering at rescues, and using the hashtag #NoPetStorePuppiesDay on social media.
