Dogs with three legs — also known as tripods — can live fit and active lives despite missing a limb. A growing number of three-legged dogs are even training and competing in a variety of sports alongside their owners. Some dogs are born without a fourth leg, while others lose a leg because of injury or illness.
Regardless of why they only have three legs or what leg is missing, many of these dogs are driven and fit enough to participate in dog sports and are increasingly allowed to do so.
Are 3-Legged Dogs Allowed to Compete in AKC Dog Sports?
Tripod dogs that are otherwise healthy and sound can compete in many AKC-recognized sports.
As of July 2025, three-legged dogs can now participate in the non-jumping obedience and AKC Rally classes. They’re also eligible to earn virtual Obedience titles.
Here is a full list of sports in which three-legged dogs can compete without restrictions:
Are Dog Sports Safe for 3-Legged Dogs?
Just like every four-legged dog isn’t physically and structurally appropriate for every sport, the same is true for three-legged dogs. “One has to consider why the dog has only three legs,” says AKC Chief Veterinarian Dr. Jerry Klein. “Was the leg amputated due to pathological reasons, such as cancer? Was the limb amputated due to extreme trauma?”
He explains that if the limb was amputated due to a disease, you need to be certain the dog is fully healthy to risk further injuring or harming the dog. But many tripods are physically active, and for these dogs, sports can be a great outlet. “Dogs losing their limb due to trauma or unique genetic malformation are more likely to do better [in sports],” Dr. Klein says.
Any dog owner wanting to start training in a sport, especially high-impact sports, with their tripod dog, should pay special attention to their dog’s health. Dogs should be in ideal weight and body condition in order to train and compete. A veterinarian should also screen them for any underlying soft tissue disease or underlying osteoarthritis of existing limbs (hip dysplasia, elbow dysplasia, spondylosis, etc.).
Dr. Klein explains that some three-legged dogs do better with sports than others, and you should consider the stress you may be putting on your dog. “When a dog has three legs, each leg takes more trauma than dogs having four limbs. This is especially true of forelimb amputees. Generally, smaller dogs fare more easily as tripods than larger dogs, but short-legged dogs with longer torsos may be more at risk for back issues.”
Assessing 3-Legged Dogs
For any AKC sport or event, a dog who the judge deems to be lame, which is defined as any irregularity of locomotion, cannot compete. In the past, sports enthusiasts may have assumed that three-legged dogs were unable to compete, but that isn’t the case. When competing, judges will evaluate a three-legged dog the same way they would a dog with four legs.
“Evaluating soundness and lameness on a three-legged dog is more challenging than with a four-legged dog,” Dr. Klein says. “Postural changes need to be evaluated, such as how the dog sits and lies down or tries to get up. Coordination, scuffing, and slipping may be other signs to help assess soundness.”
Like with any dog, you’ll want to take a tripod dog’s specific health needs into consideration before exploring sports. There is also the option of physical therapy for these dogs, as well as hydrotherapy and acupuncture. “Owners must be sensitive to their special needs of soreness and stiffness that they may be more prone to,” Dr. Klein explains.
Breaking Barriers in Dog Sports
Three-legged dogs and their owners are helping to break barriers and redefine what tripod dogs are capable of. Lark Shlimbaum and her dog “Rascal,” a 3-year-old Norwich Terrier, gained notoriety in 2021 when he became the first tripod dog to compete in an AKC agility trial. Rascal has helped change the perspective of many dog people of what tripod dogs can do, that is, if they notice his missing leg.
Rascal and Shlimbaum trained in agility before he needed his leg amputated in 2020, and he was driven to get back to the sport he loves. She recalled that two weeks after the amputation, he got his staples out in the morning, and they went to agility class in the afternoon. “I thought we would try three or four obstacles, but Rascal turned out to be his same loud, fearless, athletic self and ran a full agility course.”
Rascal, being a tripod, sometimes takes people by surprise. “Most people don’t notice Rascal has three legs, including the judges!” Shlimbaum says. “Everyone who sees Rascal in person says he is inspirational and how terrific it is that he is running in agility. It has not been uncommon to be told the Judge had no clue who the tripod was, and for other exhibitors to tell me at the end of the second day they just noticed Rascal has three legs.”
Shlimbaum and Rascal also train in Scent Work and Obedience. Rascal’s success came as a surprise to Shlimbaum, who never imagined being able to run with him in agility. “This experience has introduced me to people around the world and tripod owners and dogs around the country,” she says. “Tripods can do anything.”
Safety Considerations for Dog Sports
Dr. Klein advises that all dog owners should be thoughtful about joint health, especially those whose dogs have three limbs. If you have an active three-legged dog, he advises you to “ask your veterinarian about supplements, such as chondroitin and MSM, to support joint health. Omega-3 fatty acids may help decrease the symptoms of osteoarthritis, although there is scant definitive research.”
Any dog competing in high-impact sports, especially a tripod dog, could benefit from working with a rehabilitation veterinarian familiar with sports medicine. They’ll be able to help you assess what sports are right for your dog. Plus, they can provide advice on how to keep your dog in the best condition for training and competing.
Safety is something that Shlimbaum takes very seriously with Rascal on and off the agility field. To help, he doesn’t run on wood and tile floors and only plays in carpeted areas. Shlimbaum also carries him up long flights of stairs.
She also makes handling adjustments agility to keep him safer. “In agility class, our teacher showed us how to turn left instead of right where there was a choice,” Shlimbaum says, as Rascal’s left side has two legs. She also makes sure to keep him in top physical condition, keep his weight down, do core strengthening exercises, take shorter walks every day, and moved his jump height down from 8 inches to 4 inches.
Getting Started in Sports With A 3-Legged Dog
If you have a tripod dog at home who is otherwise fit and healthy, sports can be a great way to bond with them. “Dogs love to have a purpose. If your dog has only three legs but is mentally and physically fit and conditioned as determined by your veterinarian, most will do just fine,” Dr. Klein advises.
If you have an active tripod at home, having three legs doesn’t have to slow them down. You might be surprised where the journey takes you. Shlimbaum echoed this sentiment. “You know your dog,” she says. “Do what you decide is best for your dog and no matter what happens, enjoy every moment.”
