Will my dog stop making glucosamine if I give her supplements?

Updated on September 23rd, 2025

Pet's info: Dog | Alsatian | Female | spayed | 1 year and 1 month old | 67 lbs

Glucosamine supplements are said to have little to no side effects, mainly GI, & 50/50 on the efficacy. Many supplements however cause the body to stop producing whatever is supplemented because the body recognizes it already has enough; like how the collagen in chapstick turns a supplement into a dependence. Will my dog stop producing glucosamine because of her supplement then?

I don't think that your pup will stop making glucosamine naturally if she were on a supplement. However, I do not typically start such young dogs on this type of supplementation unless they have been diagnosed with a cartilage disorder. An appropriately balanced commercial dog food for large breed dogs will have a great balance of minerals, nutrients, and protein to support her musculoskeletal system. I also agree that the efficacy of glucosamine supplements is a bit iffy. I have seen much better results in dogs with arthritis or other joint issues with Adequan injections.
