Boaters and sea lions have a complicated relationship in Southern California, with strong opinions falling on both sides.

Bottom line, sea lions are cute but they can be a nuisance to anglers who are trying to reel in a catch or boaters who are trying to walk a narrow dock to their boat or keep their swim platform clear of a colony lounging in the sun.

In this short clip a tenacious little pooch takes it upon himself to provide mammal security on a marina dock.

He’s hardly the only one. We easily found a similar clip of a different dog charging into action.
