Dogs are more used to catching bones than waves - but not two-year-old Labrador Mango from Cornwall.
The pet's been taught to surf by her beach-going family, after she followed them out into the water one day.
Owner Matt Slater said: "She really seems to enjoy it, and she is absolutely fearless. Plus it's a great way of exercising her as she does end up doing a fair bit of swimming."
Matt's posted a video showing off Mango's talents on YouTube.
In the clip, you can see Mango riding on the same surfboard as her owner Matt.
Matt joked: "Maybe we will get invited to a dog surf contest in California."
