Re: Glucosamine for dog\'s aging joints?
Glucosamine is a form of GAG's, glucose amino glycans. These are the building blocks for the cartilage in the body. As the cartilage detiorates in the body from injury or from old age osteoarthritis sets in. Osteoarthritis is remodeling of the bone due to stress, injury, hypermobility and old age. As the joint cartilage detiorates the joint becomes unstable. The body wants to stablize this joint and will do so by starting to fuse the joint. This gradual fusing process is osteoarthritis. Glucosamine and chondroitan do nothing to help osteoarthritis directly. What glucosamine and chondroitan do is help to rebuild the cartilage. As the cartilage becomes more stable the osteoarthritic process slows down.
Glucosamine/chondroitan therefore has nothing to do with calcium or magnesium or phosphorus, building blocks of bone. They are two completely separte processes. In the absence of osteoporosis you can actually speed up the degenerative process by taking too much calcium/mag./phos.
Gluc./chondroitan due however HAVE to be taken in SPECIFIC doses to be effective. That dose is going to depend on the weight of your dog. Also the purity varies greatly from 30% bioavailable to 100% bioavailable. This means how much of the dosage the body can actually absorb and use. The best over the counter glucosamine has only been shown to be about 30% effective. You need to get the clinical results from the company and make sure that whatever you are using is tested by independent labs to assure that it is pure glucosamine. Everything from sawdust to sand has been found in supplements. It is also a very slow process. It takes a couple months for it to start to take effect and yes you do need to keep supplementing it to keep up with the joint degeneration. It also usually takes a much higher dose to begin with and then switch to a maintenance dose.
The reason a dog may have an adverse reaction is from getting way too much. The dose for a 150 lb. person is 1500 mg. Giving 1500 mg to a dog would be too much. In too high of doses it can cause diarrhea, stomach aches, digestion problems, etc. I can't tell you the exact dose for a dog. Your vet should be able to tell you that. All of the studies have shown that there is a specific amount that you have to have absorbed into the body to be effective. Below this level and it does no good at all. Higher doses also do not represent greater efficacy either. In the absence of vet recommendations I would highly suggest not giving it to your dog. If it is truely a joint problem that is related to the cartilage it will be beneficial. If it isn't you are wasting your money.
Once the problem is there it's much more difficult to get it under control. If you have an animal that is at high risk for joint degeneration it is wise to put them on gluc/chondroitan supplements to prevent degeneration. All of our dogs and performance horses are on it.
If you already have an animal that is in the degenerative process and has joint damage you will get better results by giving the gluc./chondr. with a supplement that contains MSM, Yucca, and/or willow bark. These supplements have been shown to reduce joint inflammation associated with osteoarthritis. It is the constant inflammation in the joint that also leads to increased degeneration within the joint.
