Reggie, the world’s tallest dog, and Pearl, the world’s shortest dog, recently met for an unforgettable playdate. The event, organized by Guinness World Records to mark their 70th anniversary, has captured the hearts of animal lovers worldwide.
A Meeting of Giants and Miniatures
The full story, shared by Smithsonian Magazine, gives a unique glimpse into the lives of these remarkable animals. The playdate between Reggie and Pearl was a moment of wonder, where size differences became not just apparent but a defining feature of their interaction.
While Reggie can comfortably rest his head on the kitchen counter, Pearl is small enough to fit into a food bowl — yet despite their size disparity, the two dogs got along famously.They sniffed each other, wagged their tails, and even shared a meal.
Guinness World Records Brings the Dogs Together
Guinness World Records, celebrating its 70th anniversary, organized the playdate in Idaho Falls, ensuring that Pearl, who lives in Florida, wouldn’t have to travel by plane.
“Obviously, bringing the smallest dog in the world with the tallest dog in the world, there was a little bit of anxiety,” says Reggie’s owner, Sam Johnson Reiss. “He was very gentle, very, very kind to Pearl, as best as he could be.”
Reggie, whose full name is Reginald, became the tallest living male dog in the world in January 2025, weighing 145 pounds and standing a staggering 3-foot-3 at the withers. Sam Johnson Reiss, have had to adjust their home to accommodate Reggie’s extraordinary size. He often drinks directly from the kitchen sink, and training him to eat only from his bowl has been a challenge.
On the other hand, Pearl, born in September 2020, weighs just over a pound and stands at a mere 3.6 inches tall, which earned her the title of world’s shortest dog. Her petite size is almost as impressive as Reggie’s towering presence.
“She’s really demanding,” says Vanessa Semler, Pearl’s owner. “She’s strong, and opinionated, and she can tell you what she wants.”
The Unlikely Friendship of Reggie and Pearl
What makes this meeting even more heartwarming is how quickly the dogs hit it off. Reggie, who stands at over three feet tall, was initially hesitant about Pearl, but he soon proved to be gentle with the tiny dog. Both dogs enjoyed their time together in the house.
Their interaction highlighted the universal nature of companionship, regardless of the vast differences in their sizes. Despite the size difference, the dogs proved that friendships between even the most unlikely of companions can form naturally. They wagged their tails, played together, and shared their space peacefully.


A Legacy of Record-Breaking Pets
While the chance to witness such an extraordinary meet-up might be rare, it reinforces the growing importance of celebrating animals who hold world records. Whether or not the two pets will meet again is uncertain, but their owners have expressed hope that they will remain friends forever, continuing to delight fans of all ages with their story of unlikely friendship.
