International Dog Day, the annual August 26 observance created in 2004 by animal-welfare advocate Colleen Paige, prompted a wave of tributes and adoption appeals across government, business and social-media channels on Tuesday. U.S. Customs and Border Protection used the occasion to salute its detection and search-and-rescue canines, while the U.S. Ambassador to Japan introduced “Stella,” the embassy’s newest four-legged team member. Municipalities such as Las Vegas promoted local dog parks and safety tips for pet owners. Shelters and rescue groups seized the spotlight to spur adoptions. San Francisco Animal Care & Control showcased dozens of available dogs, and Henderson Animal Protection Services in Nevada said it will waive all adoption fees through Oct. 31 under an American Society for the Prevention of Cruelty to Animals grant. Corporations also leaned in. Cryptocurrency exchanges including Binance, Coinbase, HTX and KuCoin pushed dog-themed marketing posts and giveaways, while advocacy group The Lincoln Project offered free branded bandanas for pets. Science Magazine marked the day by highlighting new genome research that traces a complex, millennia-long co-evolution between dogs and humans, underscoring the scientific as well as cultural importance of humankind’s oldest animal companion.
