Organisers have said that a record number of people attended this year's Surf Dog Surf-a-Thon in North Beach, California on Sunday.
The fourth such event saw a range of breeds competing for the top prize, the Daily Mail reports.
President of the Helen Woodward Animal Centre Michael Arms said: "It just doesn't get any greater than San Diego showing its love fordogs and its love for surfing.
"What could be more fun than playing with your dog in the water?"
He estimated that nearly 4,000 people came to watch the surfing at the annual spectacle, doubling last year's attendance.
Money raised from the event is used to send staff from the animal centre on trips as educators, while next year organisers hope to make the contest an international one.
