Arthritis management takes careful coordination.

Think of them as the silent sufferers: the millions of dogs who hobble among us, creaking away on swollen joints and dwindling cartilage. Most are older, but the years didn’t make them that way. Arthritis did.

Osteoarthritis is the biggest cause of chronic pain in U.S. dogs. According to most estimates, it affects more than 20 percent (that’s 10 to 12 million animals).

Technically speaking, osteoarthritis, or OA, is a degenerative disease involving one or more joints in a dog’s body. It most often shows up in middle-aged or older dogs, although there’s no standard age of onset, explains Jamie Gaynor, DVM, MS, director of the Animal Anesthesia and Pain Management Center in Colorado Springs, Colo.

But OA isn’t just an old dog’s disease, nor is every dog destined to be arthritic. OA is generally triggered by excessive wear in one or more joints, but dogs who have joint irregularities are more likely to develop arthritis in the affected joint. These irregularities can be caused by trauma—an accident or injury—or by a developmental deformity, such as hip or elbow dysplasia, which is a genetic condition that develops in a dog after birth.

Other factors that can contribute to OA are obesity (see sidebar) and overuse. This is a problem for racing dogs as well as for many working breeds; they may not be herding sheep or pointing at birds for a living, but many still feel compelled to run around as though they were.

Osteoarthritis is tough to manage, in part because it’s cyclical: Inflammation creates pain as well as physical changes that force the joint to move in an unnatural way, creating more pain and inflammation. Once it gets started, arthritis is difficult, if not impossible, to stop.

What’s more, just controlling the pain of arthritis is anything but simple. Researchers have found that arthritis pain follows several different pathways and creates changes in the dog’s central nervous system, which means that keeping an arthritic dog comfortable most often requires more than one type of pain relief.

There’s no cure for OA—treatment generally focuses on treating the discomfort and slowing the loss of cartilage and damage to the joints.And vets agree that there’s no silver bullet: No drug or therapy or supplement works on every dog, and no two dogs respond in exactly the same way to any treatment.

But there are steps that you can take to slow the progression of arthritis and keep your dog as happy and active as possible.

Dietary Supplements

Veterinarians’ offices, pet supply stores and Internet shopping sites are brimming with supplements, all promising to have your creaky old dog prancing like a puppy. But while there’s plenty of snake oil out there, some supplements do seem to work: some on the pain, others on the inflammation and still others on the cartilage itself.

This last group, known as diseasemodifying agents, can create changes in the dog’s body that have a direct impact on the progression of a disease, explains Dawn Boothe, DVM, PhD, professor and director of the clinical pharmacology laboratory at Auburn University’s College of Veterinary Medicine in Auburn, Ala. In a dog with arthritis, these supplements can make the cartilage healthier and better able to fight off the damaging effects of OA.

The supplements listed here can be combined with other remedies, but check with your vet before adding them to your dog’s diet. Give any supplement at least four weeks to work, says Carvel G. Tiekert, DVM, executive director of the American Holistic Veterinary Medical Association.“If you don’t see any changes after six weeks,try something else,”he says. (For another cautionary note, see the final page.)

Glucosamine and Chondroitin Sulfate. These substances provide the building blocks for polysulfated glycosaminoglycans, or PSGAGs, which are long-chain molecules that hold water and give cartilage its cushion. Research shows they can be very effective in both animals and humans. A recent study (Grainne McCarthy, James O’Donovan, et al., published in The Veterinary Journal 2007; 174[1]:54–61) found that arthritic dogs given a supplement of glucosamine and chondroitin for 10 weeks had significantly less pain than dogs who didn’t get the supplement.

I have five dogs, and two of them suffer pain from arthritis. One is much worse than the other. In fact, our vet, and an orthopedic surgeon, commented that they didn't know how Argus is able to walk, let alone get around as well as he does. He is an eleven year old American bulldog who never knew the meaning of "can't", and he always seemed impervious to pain. I guess that's why he is able to move as well as he does despite his condition. He has slowed down over the past year. He is happy with shorter walks, he sort of gallops instead of runs, and he takes his time going up the three steps into our home.

I hate to see him this way. He's always been our super dog! He's supposed to be invincible. I started doing research on ways to help him be more comfortable, and this article has given me some new things to look into. My research turned up fish oil, glucosamine and chondroitin. I actually started my own website to help others learn the benefits of fish oil for dogs. I don't sell anything on it, so please feel free to click on over: http://efishoilfordogs.com It's not that pretty, but I think it has some good information for people looking to begin their dog on fish oil supplements. Good luck to all who have dogs with arthritis. Give'm a hug from me!
