You know the saying "you can't teach an old dog new tricks?"

Well... apparently an old dog can teach a young one a trick or 2.

YouTube user Pat O'Brien posted a video Wednesday (7/29) of her 2 golden retrievers, Lily and Layla, playing at a local park. Lily loves heading down the slide. Layla... not so much.

That's until Lily persuades her to follow... by pulling on her leash until she slides down!

See... Old dogs know what's up!
