The fastest dog in the world on two front paws is a two-pound mixed breed named Konjo, and a quarter of her reported ancestry is Chihuahua. On December 22, 2014, at Tustin Sports Park in Tustin, California, Konjo covered five meters on her front paws alone in 2.39 seconds. Guinness World Records ratified the run, published the story in June 2015, and still lists Konjo as the holder of the category. More than eleven years on, nobody in the official database has taken it from her.

What the record actually measures

The category is narrow and precisely worded: fastest 5 m on front paws by a dog. The dog runs the distance on her forelimbs with her hind legs off the ground, and the clock stops at the line. Konjo's 2.39 seconds replaced a mark of 7.76 seconds set by Jiff, a Pomeranian who held several trick-speed titles in the same period. That is not an incremental improvement. Konjo cut the standing time by roughly 69 percent, which is unusual in any timed record and part of why the run drew national coverage.

Run the arithmetic on the official time and Konjo averaged about 2.1 meters per second, or roughly 4.7 mph, upside down. That figure is derived from the ratified time rather than published by Guinness. For scale, a fit Chihuahua on all four legs is considerably quicker, as our guide to how fast chihuahuas can run lays out. The record is not a speed record in the ordinary sense. It is a balance record with a stopwatch attached.

How a two-pound dog reached the record book

Konjo's owner, Julia Pasternack, approached Guinness World Records herself. According to the organization's account of the attempt, Pasternack wrote in advance that her dog would break the then-new category, and she was right. Guinness quotes her saying Konjo "started walking on front feet when she was a puppy and does it 100% naturally."

ABC News reported the same origin story, quoting Pasternack's letter describing "a very special 2 lb Papillon/Chihuahua mix who walks on her front paws on a daily basis." Pasternack's own explanation, carried by both outlets, is that Konjo's center of mass sits forward, which gives her balance on her front legs, and that her small size makes her agile enough to move that way at speed. That is an owner's theory rather than a veterinary or biomechanical finding. Neither account reports a gait analysis, and neither describes any training program behind the behavior.

The Chihuahua share of the story

The sources differ slightly on what Konjo is. Guinness World Records describes her as half Papillon, a quarter Jack Russell Terrier, and a quarter Chihuahua. ABC News, quoting Pasternack's application letter directly, calls her a Papillon and Chihuahua mix with no terrier fraction mentioned. Neither report cites a DNA test, so the breakdown is best read as owner-reported ancestry rather than a laboratory result, which is the ordinary situation for most mixed small dogs. Our overview of common chihuahua mixes covers why those estimates shift so often between tellings.

The two-pound weight comes from the same letter and carries the same caveat. It is very light even for an adult toy dog, and neither Guinness nor ABC reported an independent weigh-in or gave Konjo's age on the day of the run. Her status since is also unreported. The last substantial coverage dates to June 2015, and no outlet appears to have published a follow-up. Guinness notes on its own record pages that titles change regularly and are not always posted online immediately, so the listing is current rather than permanent.

What the record does not recommend

Konjo taught herself, according to her owner, and that distinction matters before anyone tries this at home with a four-pound dog. Moving on the forelimbs loads a toy-breed skeleton in a direction it was not built for, and Chihuahuas already carry known orthopedic vulnerabilities, notably patellar luxation, alongside the neck and airway sensitivity that shapes so much of their equipment advice. A dog who briefly chooses an odd posture on her own is doing something different from a dog being shaped into it with repetition and treats.

If your chihuahua does something similar spontaneously, note how often and for how long, and raise it at the next appointment, since a new gait can signal pain elsewhere rather than talent. If you want a trick repertoire, build it from movements that keep four feet involved, the sort of thing our roundup of fun games for chihuahuas is built around, and take any structured performance ambitions down the organized route described in our beginner's guide to dog shows. Ask your veterinarian before starting any training that deliberately loads the front limbs, and stop at the first sign of limping, reluctance, or soreness.

Frequently asked questions

Is Konjo a Chihuahua?

Partly. Guinness World Records lists her as a quarter Chihuahua, alongside half Papillon and a quarter Jack Russell Terrier, while her owner's own description quoted by ABC News was simply a Papillon and Chihuahua mix. No DNA test is cited in either account, so treat the exact proportions as reported rather than confirmed.

Does Konjo still hold the record?

As of July 2026, yes. The Guinness World Records database still lists the fastest 5 m on front paws by a dog as 2.39 seconds, achieved by Konjo at Tustin Sports Park on December 22, 2014. Guinness cautions that records change frequently and are not always published online right away, so the entry reflects the database as it currently stands.

Should I teach my chihuahua to walk on her front paws?

Not as a training goal. Konjo's behavior was self-taught, according to her owner, and deliberately loading a small dog's forelimbs is a different proposition from a dog briefly choosing the posture herself. Talk to your veterinarian before any trick work that shifts weight onto the front end, particularly for a dog with a history of joint, neck, or spine trouble.

What makes Konjo's entry hold up more than a decade later is how modest it is. There is a date, a park in Orange County, a measured five meters, a stopwatch, and a very small dog who moved in an unusual way in front of witnesses who wrote it down. No rescue arc, no resurfaced video, no larger meaning attached. Just 2.39 seconds in Tustin, California, still standing.
