There are dogs professionally trained for water rescue, but this unnamed dog isn't one of them. He just saw a puppy in trouble and...well...see for yourself.

The action starts when the puppy starts swimming across the pool, and the dog, which we assume is his dad, notices it's having a hard time. The dog immediately leaps in and gets to the puppy just as it's struggling with pulling itself up onto dry land. It tries putting its head underneath, but that's a no-go.

So instead he leaps out of the pool, comes around, and drags the pup out by the scruff of its neck. And then around the yard, presumably to teach it a lesson.

Here's our question: who is this hero dog? And can we train other dogs to be adorable private-pool lifeguards? We'd all swim more as a nation if that happened.
