National Dog Day Worldwide: How 15+ Countries Celebrate August 26 

National Dog Day is observed on August 26 in the United States and, under the name International Dog Day, in countries worldwide. Founded in 2004 by animal advocate Colleen Paige, the holiday promotes dog adoption and celebrates dogs of every breed. A handful of countries notably Japan and Nepal mark their own dog holidays on different dates.

Every August 26, millions of dog owners across the globe post photos, visit shelters, and spoil their pets with extra-long walks and treats. What began as a single American awareness campaign two decades ago has since spread to dozens of countries, each adding its own cultural flavor to the celebration.

Is National Dog Day a Global Holiday?

National Dog Day started in the United States in 2004 and gradually expanded internationally. By the early 2010s, organizations and dog lovers outside the US began observing the same date August 26 under the name International Dog Day. It is now recognized in dozens of countries, though it remains an unofficial observance rather than a public holiday.

Pet and family lifestyle expert Colleen Paige founded National Dog Day on August 26, 2004. She chose that date to mark the anniversary of the day her family adopted their first dog from a local animal shelter. The US government formally recognized it in 2013. Since then, animal welfare organizations from London to Sydney have adopted August 26 as their own awareness moment, and the hashtag #InternationalDogDay now appears in dozens of languages every year.

The scale of that interest makes sense. According to World Population Review, there are between 700 million and 1 billion dogs worldwide, with approximately 30% of global households owning at least one. That’s a large, passionate audience with every reason to celebrate.

Most countries follow August 26, but two nations have their own distinct dog holidays rooted in local culture.

Japan: Inu no Hi (November 1) 🇯🇵

Japan celebrates 犬の日 (Inu no Hi) Dog Day on November 1. The date comes from a numerical wordplay: the Japanese onomatopoeia for a dog’s bark is wan wan wan, and “wan” sounds like the number 1. So 1/1/1 → November 1. The holiday was established by Japan’s pet food industry. Japan has approximately 6.8 million pet dogs, and the day is marked with pet store promotions and social media tributes. Japanese dog owners also observe August 26 as International Dog Day.

Nepal: Kukur Tihar (October/November) 🇳🇵

Nepal’s Kukur Tihar is one of the world’s most culturally distinctive dog celebrations. It falls on the second day of the five-day Hindu Tihar festival, which occurs in October or November depending on the lunar calendar. On Kukur Tihar, dogs both owned and stray are adorned with flower garlands (mala), given a tika (a mark of blessing) on their foreheads, and offered a feast including eggs, meat, and milk. According to the BBC, the celebration extends to all dogs on the street, not just pets.
