Dunkin' and BARK have opened their first-ever official dog drive-thru experience in Quincy, Massachusetts, in celebration of National Dog Day.

For one day only on Wednesday, the Quincy Dunkin' kept one drive-thru lane open for regular guests while reserving a second lane exclusively for dogs. Pups passing through received dog treats and limited-edition BARK x Dunkin' bandanas, while plush toys from the new BARK x Dunkin' collection were available with a donation to the Dunkin' Joy in Childhood Foundation.

"For years, dogs have been riding shotgun on Dunkin' runs with their favorite humans. This National Dog Day, Dunkin' is returning the favor," the press release announcing the initiative reads.

This year's plush toys were inspired by some of Dunkin's popular menu items, including a Wake-Up Wrap Dog Toy, a Strawberry Dragonfruit Refresher & Donuts Dog Toy, and a Dunkin' Iced Signature Latte & Chocolate Frosted Sprinkles Donut Dog Toy.

Now in its seventh year, the Dunkin'-BARK partnership has raised more than $15 million for the Dunkin' Joy in Childhood Foundation and sold more than one million dog toys. The collaboration reflects a broader shift among quick-service chains toward pet-friendly marketing, as brands increasingly court the roughly half of U.S. households that own dogs — a demographic Dunkin' itself has leaned into in recent years with items like a cup-pup whip for dogs (a whipped-cream treat for four-legged guests).

"Seven years and a million toys later, this tradition has become something dog parents look forward to," said Dave Stangle, Vice President of Brand Marketing at BARK. "And it all comes back to the rituals we have with our dogs, that dogs go where their people go. The drive-thru makes that official. This year, dogs aren't just tagging along, they're the ones being served."

The event, dubbed "Dunkin' for Dogs," extended beyond the Quincy store. Select Dunkin' restaurants in New York, California and Illinois offered limited-edition BARK x Dunkin' bandanas alongside the new BARK x Dunkin' plush toys to mark National Dog Day.

Donations benefit the Dunkin' Joy in Childhood Foundation's programs supporting children battling illness and hunger, including Dogs for Joy, which places highly trained facility dogs in children's hospitals across the country. Dogs for Joy grants have supported 54 facility dogs at 37 hospitals nationwide.

These dogs support young patients by teaching them how to take medication, providing comfort during medical interventions, and motivating them through treatment.

"The BARK collaboration has become a beloved tradition because it brings together so many things our guests care about: their pets, their communities and giving back," said Mollie Collum, Director of the Dunkin' Joy in Childhood Foundation. "Every toy represents an opportunity to help support our programs like Dogs for Joy, and we're excited to make this year's celebration even more memorable with Dunkin's first official dog drive-thru."
