This white boxer dog got more than he bargained for when he wandered into the sea off the coast of Scotland to get his owner's ball back...
The dog was only metres from the shore, when a baby seal bobbed up to say hello!
At first the dog just walked in circles around the seal, to try and figure out what was going on.
But then the seal stretched out one of his flippers to show the dog who was boss!
And then the seal slapped the dog on the nose! These pictures were snapped by a woman watching the action from the shore.
She said: "The dog went right up to the pup for a sniff and he cheekily slapped him on the face with its flipper." And it doesn't look like he ever got his ball back!
