A playdate between the world’s tallest and smallest living dogs went the way of most dog park encounters despite the 3-foot height difference—lots of tail wagging, sniffing, and scampering.

Reginald, a 7-year-old Great Dane from Idaho, and Pearl, a chihuahua from Florida, are both certified winners in their respective height titles by Guinness World Records.
