Prosthetics, if made right, can restore that variety of movement. But as heart melting as it is to see a three-legged dog return to running on four legs, it’s not simple to construct an appropriate pup peg leg. Wendland, who works with the prosthetic and orthopedic business OrthoPets to assist canines adjust to their brand-new limbs, says that it’s an involved procedure that takes some time and technical knowledge.

. Maybe they were born with an unusual limb, or were hit by a car, or established a cancerous growth that demanded an amputation. A common quip among tripod lovers is that “dogs have three legs and an extra.”It’s true, to a point.

Pet dogs adjust remarkably well to losing a limb, says Theresa Wendland, who focuses on animal sports medication and rehab at the Colorado Veterinary Specialist Group. However issues can develop as the animal compensates for what’s missing. In older canines and pets with arthritis or other movement concerns, putting additional weight on the staying limbs can be a big problem.

They need to pull themselves forward in methods that are very unnatural.”

More and more, that desire to assist manifests as prosthetics, particularly in cases where the animal has lost more than one limb. Dogs adjust remarkably well to losing a limb, states Theresa Wendland, who specializes in animal sports medication and rehab at the Colorado Veterinary Specialist Group. In older pets and pet dogs with arthritis or other movement issues, putting additional weight on the remaining limbs can be a huge problem. To do that, orthopedists have to study the animal’s movements and try to mold a limb that will sync up with the others. The perfect spot to put a prosthetic, Wendland says, is as low on the limb as you can go.

Just like human prosthetics, an animal prosthetic has to be separately tailored to the construct of the wearer. That suggests factoring in the animal’s size, weight, gait, height, and position. (A set for a doberman will not fit on a dachshund.) To do that, orthopedists have to study the animal’s motions and attempt to mold a limb that will sync up with the others. While strategies differ, a basic process is to make a plaster cast, style the prosthetic based on images and video, then build it out with resilient thermoplastics and metal. From there, they modify the finer information by hand up until it works with the animal. The process can take weeks.

There’s also the matter of the quantity of the limb that needs replacing. The perfect area to put a prosthetic, Wendland says, is as short on the limb as you can go. But if the entire limb is gone and there’s no obvious indicate attach a prosthetic, it gets much trickier.

A Leg Up

3D printing has actually long been hailed as a manufacturing transformation in lots of markets, prosthetics among them. And now, a New Jersey– based design company called Dive Design thinks it’s the option to full-limb replacement. It has actually partnered with a company called Bionic Pets that constructs precisely what its name implies: accessibility tech for animals. Derrick Campana, who runs Bionic Pets, has long developed family pet prosthetics by hand. (He’s even got a show about it called The Wizard of Paws, which airs on Brigham Young University’s television channel.) About a year earlier, he invited Dive Design heads Alex Tholl and Adam Hecht to his laboratory in Virginia to take a look at how he could enhance the process.

“Something that kept coming up was the need for complete limb prosthesis development,” Tholl states. The limbs that Campana had actually been constructing used a lot of resources and needed excessive labor to be workable. Plus, Tholl states, “With the waste that was involved, it simply didn’t make monetary sense. For us, that’s when the wheels began turning.”
