World's Tallest Dog And Smallest Dog Meet For Cute Play Date. Watch The Video

A sweet play date between the world's tallest dog and the world's smallest dog is proving friendship can come in any size.

The folks at Guinness World Records shared a montage video on Instagram that showed a meetup between Reggie, a 7-year-old Great Dane from Idaho Falls, Idaho, who at 3 feet, 3 inches tall, holds the record for the tallest living dog (male), and Pearl, a 4-year-old Chihuahua from Orlando, Florida, who is the smallest dog alive at just 3.59 inches.

The cute clip, shot earlier this month at Reggie's house, shows Pearl lounging in Reggie's food bowl as Reggie, towering over her, gives her head a few gentle sniffs.

It also shows the two fast friends — whose height difference is more than three feet — lounging together on a sofa and hanging out together in Reggie's grassy yard.

"It was a really fun and exciting day," Pearl's owner, Vanesa Semler, told Guinness World Records. "(Reggie) was absolutely adorable, playful like Pearl."

Reggie's owner, Sam Johnson Reiss, agreed the day was a huge success.

"I was surprised Pearl wasn't more afraid of Reggie. But she was so excited and interested in him, and he was just like 'Whoa, I have no idea what that is!'" they joked.

It turns out that despite their wildly different statures, the two pooches have a lot in common.

"They have more similarities than differences," said Reiss. "People say, 'Only small dogs wear clothing,' but Reggie has a bunch of sweaters he wears… 'Small dogs are high maintenance,' but Reggie is very, very high maintenance. So I think they're more alike than they are different."

Though he was born the runt of his litter, Reggie quickly made up for lost time, said Reiss, who had never owned a big dog before bringing Reggie home.

"From the time I got him until he was about, I'd say a year and a half, he just grew, like, just non-stop growth," Reiss said. "Everybody was like, he's really tall. We've never met another dog that's taller than him."

Despite holding a world record for his height, Reggie is still a playful pup at heart. "Reginald's personality is deceived by his name," said Reiss. "It makes him seem more regal or proper, but he's just a big baby."

"He acts like a human toddler. He's super playful, very vocal — very much, he'll tell you what he wants, when he wants it," they added.

Though Reiss and the rest of their family have had to make special accommodations for Reggie's height, they've also learned that having a canine giant in the home comes with unexpected perks.

"I'd say the major advantage to having a really tall dog is I don't have to bend down to pet him, he's just right at my arm's length," joked Reiss.

Semler also provided details about how Pearl came into her life, revealing that her doctor advised her and her husband to get a dog after they experienced health challenges.

"Some people like me, we can't have human babies, so (dogs) are a real part of the family, and that is a big deal," said Semler. "I strongly believe people who care and love animals, also care and love other human beings."

Though Pearl is small in stature, she's got a "big personality," said Semler. Pearl loves wearing clothes, including sunglasses and hats, and also likes getting her nails painted.

"Pearl's wardrobe, I think, is bigger than mine," said Semler, adding, "She actually chooses what she wants to wear each day, and it's really funny for me because I can actually see her mood that day."

Pearl has even been known to model her wardrobe for the camera and has a temperament that wouldn't be out of place in certain fashion circles.

"She's really demanding," said Semler. "She's strong, and opinionated, and she can tell you what she wants."

World's Tallest And Shortest Dogs Bond During Record-breaking Meetup

Among the things these two Guinness World Record holders have in common? A sizeable wardrobe and diva behavior.

IDAHO FALLS, Idaho — In a meeting that gives new meaning to the phrase "opposites attract," the world's tallest and shortest dogs came face-to-paw earlier this month.

Reginald, who goes by Reggie, a Great Dane from Idaho standing 3 feet 3 inches tall, and Pearl, a 3.59-inch Chihuahua from Florida, bridged their 3-foot height difference during their first-ever meetup at Reggie's home.

The Guinness World Records title holders — Reggie for tallest living dog (male) and Pearl for shortest living dog — got along surprisingly well despite their dramatic size difference.

"When Pearl meets bigger dogs, she is really friendly. I think she has no idea she is a small dog," said Vanesa Semler, Pearl's owner, who made the journey from Florida to Idaho for the meetup to spare Reggie from an uncomfortably tight flight. 

The encounter, coordinated by Guinness World Records as part of its 70th anniversary celebration, went even smoother than expected. Reggie, seemingly aware of his massive size, was notably careful around his tiny new friend.

"Obviously, bringing the smallest dog in the world with the tallest dog in the world, there was a little bit of anxiety," said Sam Johnson Reiss, Reggie's owner. "He was very gentle, very, very kind to Pearl, as best as he could be."

After initial introductions indoors, where Pearl happily ran across Reggie's giant legs "like he was a big teddy bear," the pair ventured outside to explore together. Both dogs eventually tired themselves out from play, taking well-earned naps.

Despite their size difference, the two dogs found common ground. Among the things they have in common? A sizeable wardrobe and diva behavior. 

"They have more similarities than differences," said Johnson Reiss. "People say 'only small dogs wear clothing', but Reggie has a bunch of sweaters he wears… 'small dogs are high maintenance', but Reggie is very, very high maintenance. So I think they're more alike than they are different."

"Pearl's wardrobe, I think, is bigger than mine," Semler added. "She loves clothing, I think because she's always cold."

"I think you can see through the photos and videos the love we have for our pets," Semler said. "They're part of the family."

As for the unlikely friendship that formed between these record-breaking canines, Reggie's owner believes the pair will be "friends fur-ever."
