I just saw this: EDIT: Shark attack in Live-TV
Yes, it looked scary. But let me recap: a shark stopped by (probably curious), tangled unexpectedly in the foot-line and thus dragged the surfer from his board into the water.
The shark didn’t bite him despite having the time and opportunity. And despite being kicked and punched by the frightened surfer.
This is already a shark attack?
Transferred to a dog in it’s backyard (yes, the oceans do still belong to the fish), nobody would call this a dog attack, even if the dog did take a bite.
