A dog was seen playing fetch with his owner in a very different kind of backyard, swimming around in Falmouth Harbour.

The video, filmed September 27, shows the salty seadog running down the steps of the seawall then leaping into the water to catch his owner's float.

“I was minding my own business, enjoying a pasty by the sea... and then sploosh. I turned to see a sea wise dog jumping in to retrieve his masters float. He never ever tired of doing this over and over again,” said Emily Costello the filmer.
