A symphony of woofs: This is what happens when 2,397 golden retrievers gather in an Argentina park

BUENOS AIRES, Argentina — A passerby could hear the cacophony from miles away in the Argentine capital, the unmistakable sound of 2,397 dogs barking — and breaking the unofficial world record for the largest-ever gathering of golden retrievers.

Excitement pulsed through Bosques de Palermo, a sprawling park in Buenos Aires, as golden retriever-owners from all over Argentina transformed the park's grassy expanse into a sea of bright yellow fur.

Dog owners of all ages, their clothes covered in dog hair and stained with slobber, plopped down on picnic blankets with their beloved goldens to take in the surreal sight of so many other, exceptionally similar-looking ones. Children squealed with delight and giddily petted every dog that pranced about.

Families posed for pet selfies under the blazing Southern Hemisphere's summer sun.

Sipping Argentina's traditional yerba mate drink, attendees swapped fun facts about their favorite breed — such as goldens' famed ability to sniff out low blood sugar and cancer — and shared stories of their retrievers comforting them throughout all of life's ups and downs.

''Since we were children, she's been a constant presence in our family. We've had vacations with her. We've done everything together," said Nicolás Orellana, a 26-year-old wearing a T-shirt with a photo of a golden retriever on it. His family said they drove an hour and a half from their hometown in Buenos Aires province for the event.

''It's a type of dog that's known to create a special bond," he said, kneeling to pet his contented-looking 13-year-old dog Luna.

Through the tsunami of tail-wagging and treat-giving, 10 dog-loving volunteers clad in yellow vests roved with clipboards to register each golden retriever in attendance.

After hours of meticulous counting, the final number came in late Monday. With 2,397 golden retrievers recorded, the event's organizer, Fausto Duperre, announced that Argentina had broken the informal world record set last year when an event in Vancouver drew 1,685 goldens.

''This is a historic event,'' gushed Duperre, a 28-year-old Argentine actor who has become something of a golden retriever influencer on social media, where he regularly posts content about his 10-year-old golden named Oli.

''I'm truly grateful and happy, proud, excited and overjoyed all at once,'' he added.

High hopes for a big group photo of the dogs alone on the field quickly faded as it became clear that no owner — nor dog — would withstand even a few moments of separation. Plus, there was the all-too-real fear of dogs getting lost among their thousands of furry counterparts. Owners yanked at leashes and wrangled with the most restive dogs to keep them close.
