Smallest Dog in the World

Milly, a Chihuahua from Dorado, Puerto Rico, holds the Guinness World Record for smallest dog by height—just 3.8 inches tall, shorter than many smartphones! She lives a pampered life with her devoted pet parents, sleeping in her own baby crib and receiving constant supervision. Despite her petite stature, Milly’s bold personality shines through: she’s always trying to convince her humans that she’s ready for adventure—even if they’re not quite convinced yet.

Smallest Cat in the World

Tinker Toy, a cat from Taylorsville, Illinois, measured just 2.75 inches tall and 7.5 inches long at age 2.5 years—earning her the title of world’s smallest cat. Born on Christmas Day, 1990, as the runt of her litter, she lived a quiet, private life until her passing in November 1997. No known photographs survive, adding to her mystique—and making her one of the most enigmatic legends in FurPetVo’s archive of extraordinary pets.

Longest Tail on a Dog

Keon, an Irish Wolfhound from Westerlo, Belgium, boasts the longest tail ever recorded on a dog: 30.2 inches from tailbone to tip (excluding fur). Known as “the gentlest of giants,” Keon spends his days outdoors with his human family—including his parents and siblings—enjoying walks, naps in the sun, and plenty of affection.

Longest Cat in the World

Ludo, a Maine Coon from Wakefield, United Kingdom, holds the record for longest domestic cat at 3 feet, 10.59 inches—verified on October 16, 2015. Though his size makes him a bit clumsy (and a hopeless hide-and-seek player), Ludo is deeply cherished by his family. They remind him daily that not every cat earns a place in FurPetVo’s Hall of Fame—and that love has nothing to do with length.

World’s Tallest Horse

Big Jake, a 15-year-old Belgian gelding living at Smokey Hollows Farms in Poynette, Wisconsin, stands an astonishing 20 hands, 2.75 inches (82.75 inches) tall and weighs about 2,600 pounds. His daily diet includes a bale and a half of hay plus 32 quarts of oats. Now happily retired, Big Jake enjoys his favorite pastime: “hairdressing.” He loves gently playing with his humans’ hair—and though he may not open a salon anytime soon, his fans at furpetvo.com adore his gentle, playful spirit.

Highest Horse Jump

On February 5, 1949, Huaso—a horse originally named Faithful—and his rider, Captain Alberto Larraguibel Morales, cleared a record-setting jump of 8 feet, 1.25 inches. Huaso’s path to greatness wasn’t straightforward: after an unsuccessful start in racing and a career-ending injury in dressage, he found his calling in showjumping at age 16. After that historic leap, Captain Morales wisely retired him—allowing Huaso to live out his remaining 13 years as a beloved, record-holding legend.

Highest Bar Jump by a Llama

Caspa, a llama from Northwich, United Kingdom, soared over a bar set at 3 feet, 8.5 inches on June 14, 2015—earning the Guinness World Record for highest bar jump by a llama. Once known for a fiery temperament—including spitting and kicking—Caspa transformed through patient, positive training. Today, he’s a calm, confident ambassador for llamas everywhere, proving that with kindness and consistency, even the most challenging personalities can shine.

Longest Fur on a Rabbit

Franchesca, an Angora rabbit, holds the record for longest fur on a rabbit: 14.37 inches—longer than a foot-long sub sandwich! Verified on August 17, 2014, her luxurious coat once drew comparisons to a Pekingese dog. Now retired from the spotlight, Franchesca enjoys motherhood with her four kits—and proves that fame and family life can go hand-in-paw.

Fastest Tortoise

Bertie, a resident of Adventure Valley in Brasside, Durham, UK, broke the tortoise speed record on July 9, 2014—racing at 0.28 meters per second (0.92 feet per second). He easily surpassed Charlie’s 1977 record of 0.125 m/s. Bertie now lives in style alongside his longtime companion, Shelly, in a spacious, sun-drenched enclosure—where their favorite pastime is sharing strawberries. FurPetVo fans eagerly await news of any upcoming hatchlings!

One Parrot, Two World Records

Zac the Macaw from San Jose, California, earned not one—but two—Guinness World Records: opening 35 cans in 60 seconds, and slam-dunking 22 basketballs in the same time. A star performer with the “Happy Birds” troupe, Zac also rides scooters and skateboards, rolls over on command, raises flags, and speaks over 100 words. His talents make him a true standout—and a beloved icon across furpetvo.com’s community of clever, capable pets.
