A really expensive car can go from zero to 60 in less than six seconds, but that car would have nothing on Harvey, a seven-month-old Mastiff/Husky mix, who went from being an $85 dog to a $2,000 dog in less than four hours. That’s how long it took Harvey to be adopted from the Tacoma Humane Society, perform a cursory inspection of his new home on the fourth floor of an apartment building in Seattle, race out onto the outside terrace to check out the dog house and vault over the surrounding hip wall. Harvey hit an awning, landed on the sidewalk and ended up in the emergency room with a badly broken right rear leg that later had to be amputated. “The vet said they usually try to pin the leg first,” says Lindsey Votava, who had fallen in love with Harvey on Petfinder.com, “but with the extent of Harvey’s injury it would have been like trying to put together a bag of potato chips.”
Votava and her husband, Leif Dalan, were clear that having Harvey’s leg amputated would give him the best chance of recovery. Trying to save the leg would have doubled their vet bill and meant they would have had to immobilize Harvey for up to eight weeks, which would have violated several of the laws of physics. “Harvey walked up the stairs after his surgery,” recalls Votava, and never missed a beat. He maintains a wicked Frisbee schedule at the dog park and does everything a four-legged dog does, except “he can’t scratch his ear.” They give him glucosamine for his joints and try to keep him from overexercising so that he doesn’t injure his remaining limbs. “We have to think for him,” Votava says. “That jumping off the roof was how he is. He’s a totally go, go, go kind of dog.”
It’s not unusual these days for a dog to lose a leg, generally for one of two reasons: they suffer some sort of accident or trauma, like Harvey’s, or they develop bone cancer or other bone disease. The latter is what happened to Bernie, an eight-year-old Rottweiler whose left front leg was amputated in January. Bernie was recovering nicely from surgery to her anterior cruciate ligament (ACL) when her guardian, Tom Tilden, noticed she was limping and not bouncing back as quickly as he had expected. An X-ray showed bone cancer. “The first vet we consulted suggested giving her painkillers until the pain got to be too bad and then having her put down,” says Tilden. “We found another doctor.”
Bernie’s situation is completely different from Harvey’s. Harvey is lean and lost a rear leg while he was still a puppy; he was able to adjust immediately. Bernie is a stockier breed and lost a front leg relatively late in her life. “The front leg accounts for approximately 70 percent of the dog’s strength and balance,” says Sheila Wells, a hydrotherapist in Seattle who works with Bernie several times per week. “That is why front-leg amputees often have a more difficult time adjusting to their new state. The rear can follow but the front has to lead.”
Wells says that in her experience, most three-legged dogs are “very highly functioning.” Some dogs do better than others, depending on their size (smaller dogs have an easier time), age and other physical problems. “The biggest challenge a dog faces when it loses a limb,” says Wells, “is that it has to relearn proprioception, which means it needs to get a new idea of where its body is in space and how to balance; it’s like the bubble in a level.” The most important challenge for tripod-dog owners, she says, is to protect the remaining limbs; often people will let the dog overdo it, and that ends up putting undue stress on the dog’s joints, which can lead to injuries and arthritis. She recommends that owners observe the following checklist to keep the three-legged dog healthy for as long as possible:
• Protect remaining limbs
One of those animals was Wortman’s Clover, a one-and-a-half-year-old Pointer/Border Collie mix who arrived at the shelter with a badly broken right front leg that had to be amputated. “She was up and running the day after surgery,” says Wortman. “She’s a very athletic dog. She keeps up with the Greyhounds at the park. She’s inspiring to everyone who sees her.” Wortman says that she has noticed that people’s acceptance of three-legged dogs is growing. “Before, perhaps, people would have thought it was sad that she was missing a limb. But that has changed. I was recently at the dog park and met a couple whose baby had a paralyzed right arm. They said to me, ‘I wish we could get a three-legged dog so our child could grow up to think it was okay to be missing a limb.’”
“We always try to save the limb first,” says Thomas Mason, director of veterinary services at Pets Unlimited, “though sometimes this is much more expensive and requires more rehabilitation.” An amputation typically costs $1,200, while it may cost up to $3,000 to try to salvage the limb.
Before doing an amputation, a vet must decide if the dog is a good candidate. “We assess the animal’s overall physical condition. If the dog has arthritis in the other legs, for instance, he wouldn’t be such a good candidate. Amputation causes wear and tear on the other joints.” Many times, says Mason, a vet will end up taking off a dog’s entire leg, even if the trauma or the cancer is low down on the “ankle” joint. “Because of the way dogs walk, you end up with a lot of problems if you leave some of the limb. It would just get in the way. Most of the time, amputation is more cosmetically acceptable.”
Martin Kaufmann would like to see a change to this type of practice. Kaufmann, of OrthoPets.com, makes prosthetics and orthotics for both “two-legged and four-legged animals and any variation in the middle.” His goal is “to get the animal world up to speed with what we’re doing with humans.” He began his practice with animals four years ago, after a cousin’s Schnauzer suffered a stroke and lost the function in its right front leg. Kaufmann began studying animal anatomy books and learned that the muscle and bone terminology in dogs is almost exactly what it is in humans. Now, 30 percent of his practice is making artificial limbs and braces for animals, mostly dogs. “When three-legged dogs are brought to me, when they are amputated way up at the joint, there aren’t many options,” he says. Too often he sees animals who had cancer in the “wrist” joint.
“The vets tend to think of it as a useless limb and amputate way up at the top. That makes it almost impossible to build a prosthesis. We need at least one joint in order for the animal to be able to operate” with a prosthetic limb. Kaufmann explains that since this is a new field and he is one of only a few people doing this type of prosthetic work, not many vets know of this option. But he is trying to spread the word. “For limb preservation, it’s important to salvage as much of the limb as possible, or as many joints as possible.” If the limb has already been amputated at the top, he recommends having the dog use a cart to maintain the weight distribution on the leg that’s left. “Compounding forces on the remaining leg can cause arthritis from overuse. If the animal loses the remaining leg, what does it have left?”
Whether a dog loses a leg due to trauma or disease, most often he or she will bounce back and learn to adjust. As Sheila Wells points out, dogs don’t have the same stigma that we would have about losing a limb. “Some don’t ever notice their leg is missing,” she says. “Usually a leg that has been taken off has been painful for a long time and the dog is already used to not using that leg. When they get it removed, their whole demeanor changes because they can run around without being in pain. There’s no reason a three-legged dog has to be disabled.”
