Yorkie jumps on larger dog's back for pool-time piggyback

July 2 (UPI) -- A YouTuber taking a swim with two canines captured the moment the smaller of the two dogs jumped onto the larger one's back while it was swimming.

A video posted to YouTube by Cat Hursh shows a large black dog named Riley being coaxed into the pool to pursue a floating toy.

Riley slowly and methodically climbs into the water and swims only a few feet before a Yorkie named Sadie takes a flying leap from the edge of the water.

Sadie flies directly to Riley, landing on the larger dog's back and holding on as she swims.
