On Sunday, September 24, a park in Willaston, Australia, went to the dogs—specifically, 576 border collies gathered there in an attempt to break a record. According to The Daily Dot, the group of herding animals now holds the unofficial record for the most border collies ever to occupy the same space at the same time.

The event was hosted by the Border Collie Owners of South Australia, or BCOSA. Each pet was charged $5 to participate, allowing BCOSA to raise more than $6000 for the local charities Scruffer Lovers, Guardian Angel, and SA Dog Rescue. Along with helping out some great causes, the massive play-date also made for a once-in-a-lifetime spectacle for border collie lovers. Check out the fluffy mayhem below.

Though impressive, the crowd of canines isn’t eligible for an official Guinness World Record. Guinness doesn’t recognize records from specific dog breeds. They have, however, awarded different types of animal assemblies in the past, like this group of 764 bandana-clad dogs that met in Australia in 2015.

The latest reported world record seems specific, but it isn’t the first of its kind. Before Sunday’s crowd gathered, the record belonged to a vet who managed to get 503 border collies together in 2013.
