The cherished “surf dog” transformed a unique beach activity into an international sensation. She departed early Monday morning in the arms of her owner, Ryan Rustan.

Just weeks prior to her passing, Sugar rode one last wave — a poignant send-off for the dog many believe revolutionized the sport.

Rustan conveyed the news through a heartfelt social media message, stating, “She absolutely loved you guys!! she lived to put smiles on faces, volunteer, to send it !! to change dog surfing forever !!!”

“thank you for loving Sugar, Good bye my Sugar., i can’t believe in writing this .. i’m going to miss you so much,” the post added.

Who was Sugar?

Beyond her surfing achievements, her influence was equally significant. Sugar collaborated with surf therapy organizations and made visits to veterans at the VA Hospital in Long Beach, sharing the same happiness on land that she brought to the ocean.

Sugar's GoFundMe campaign launched before death

Before her death, Sugar fought a public battle against cancer. In a GoFundMe campaign aimed at covering the dog's medical expenses, which nearly reached its $16,000 target, Sugar's owner, Ryan Rustan, stated: “We’ve been fighting her cancer together — vet visits, special food, medicines, and all the little things I’ve bought to keep her comfortable and happy on the waves."

“Every donation helps cover what I’ve already spent and helps me prepare for whatever comes next."

“Sugar has brought so much joy to so many. If his story has touched your heart, any support means the world.”
