National Small Dog Day

Celebrated on 02/26/2026

Quick Fact

National Small Dog Day, celebrated on September 23rd, honors dogs under 20 pounds. Small dogs often live longer than larger breeds, with many reaching 15-20 years. The holiday was created to encourage adoption of small dogs from shelters, as they are often overlooked for larger breeds.

Origins and Establishment of National Small Dog Day

National Small Dog Day was established in 2017 by celebrity dog trainer and author Cesar Millan. Millan, known for his work with dogs of all sizes, recognized that small dogs often face unique challenges and misconceptions, such as being seen as fragile or yappy. He created the day to celebrate small breeds and promote their adoption from shelters and rescues.

The date September 23 was chosen to align with the start of fall, a season associated with coziness and companionship—qualities that small dogs embody. Millan encouraged owners to share photos and stories of their small dogs on social media using #NationalSmallDogDay.

Evolution and Modern Commemoration

Since its inception, National Small Dog Day has grown in popularity, with animal shelters and rescue organizations hosting adoption events focused on small breeds. Many pet stores and brands offer discounts on small dog supplies, and social media campaigns highlight the joys of small dog ownership.

Today, the day also serves as an educational opportunity to address common misconceptions, such as the idea that small dogs need less exercise or training. Events often include training workshops, meetups, and fundraisers for small breed rescues. The holiday has expanded globally, with participants from countries like Canada, the UK, and Australia.
