Remedies for Arthritis in Dogs: Glucosamine, Chondroitin Sulfate, Steroids, and NSAIDs




By their nature, nutraceuticals are substances that are consumed orally as an addition to a normal diet. These substances are much safer than traditional "drugs" in that they can be considered a form of food or nutrient. Toxicity levels are rarely a problem as long as they are used in reasonable amounts.


Today, the most commonly used nutraceuticals in pet health care are glucosamine and chondroitin sulfate. Although with traditional drugs dogs would demonstrate improvement and apparent comfort almost immediately, many have undesirable side effects. Conversely, nutraceuticals have little to no side effects but may take several weeks to months of administration before noticeable improvement in mobility and attitude are apparent.


1. Glucosamine

Glucosamine is a naturally occurring compound composed of a sugar and an amino acid and is involved with the body's production of joint lubricants and shock absorption necessary to maintain healthy cartilage and joint function. It is manufactured in the body in the joint cartilage and is one of the major components involved with the formation of the critical lubricants and shock absorbers necessary to maintain and restore healthy joint performance. Glucosamine sulfate is also one of the building blocks of articular cartilage and aids in the rebuilding of damaged cartilage.


Glucosamine sulfate is also beneficial to other other body structures besides joints. It is involved in the formation of nails, tendons, skin, eyes, synovial fluid, bone, ligaments, heart valves, and in mucous secretions of the digestive, respiratory, and urinary tracts. It is created in the production of proteins associated with cellular growth and structure.


Glucosamine as a nutritional supplement is extracted from crab, lobster, or shrimp shells. There are three forms of glucosamine, so when purchasing it, look for the sulfate form because it seems to be absorbed and utilized the best. Because dietary supplements are unregulated, the quality and contents may vary widely. Be sure to choose a product sold by a well established company and consult your veterinarian as to which would be best for your dog.


2. Chondroitin Sulfate


Research on chondroitin sulfate suggests it may be beneficial in preventing stress injuries to joints as well as aiding in the repair of damaged connective tissue. Unlike pain killers, which only serve to dull the pain, chondroitin sulfate addresses the disease process itself. Chondroitin sulfate may actually help the body to repair damaged cartilage and help restore joint integrity. It may also protect existing cartilage from premature breakdown as well as keep cartilage tissue hydrated and assist in cushioning impact stress.


Some studies suggest that supplementation with chondroitin sulfate can reduce joint pain significantly. Other studies have shown that combining chondroitin sulfate with glucosamine might improve each substance's beneficial effects, though this is not universally accepted.


Because chondroitin production by the body decreases with age, supplementation with this compound may be especially helpful for older dogs with arthritis.


Other Joint Sparing Products


The green-lipped mussel called Perna canaliculus is a source of chondroitin and other beneficial nutrients, and the sea cucumber is believed to provide assistance in the elimination of pain. They provide essential nutrients required by cartilage. Another arthritis fighting supplement is called methylsulfonylmethane (MSM). It provides sulfur compounds that may inhibit pain.
