Humpback whales occasionally swim to boats as if curious about their human occupants. It’s a behavior described as mugging.

But on Saturday off San Diego, a humpback whale seemed more curious about a furry rescue dog named Fin – and vice versa.

Dominic Biagini, owner of the company, stated via Instagram: “Watching my dog fall in love with whales has been one of the great joys of my life!”

The heartwarming interaction occurred after Jess Aubry, a Gone Whale Watching San Diego captain, encountered a large pod of humpback whales during a five-hour excursion. Biagini traveled to the location with his partner, Erica Sackrison, and Fin.

Sackrison commented via Instagram: “Who’s watching who?”

Aubury remarked: “That tail is going a mile a minute.”

One follower observed that Fin seems to be the boat’s only occupant.

Fin, a mixed yellow lab/golden retriever, was rescued by Biagini near the U.S.-San Diego border.
