Topic: Glucosamine & Chondroitin Dosage?

Posted By: colochoclab on 09/27/09 06:23pm

Is there a general guidline for dosage in dogs? I have been giving Hershey his supplements for quite some time now, but I am having doubts about the correct dosage. His orthopedic surgeon gave me a dosage scale years ago, but the amounts escape me.

My local Target store had the combo on sale, so I picked up a bottle: The bottle amount is 1500mg Glucosamine / 2050mg Chondroitin contained in 4 tablets.
I was going to give Hershey 2 tablets for a dose of 750/1025. He weighs 80#. (Of course it's Sunday, so my vet isn't in the office!)

Thoughts? Dr. Doug, are you out there?

well I take one full dose a day but I weigh more than 80 lbs. myself. but shop around and read the labels. you can buy these tablets with full amount in one tablet and can break it in two if desired. I certainly don't think that an 80 lb. dog would OD on a whole tablet myself.

Note: Because of the variability in products available, it is recommended to choose a product that has been tested in the species for which it is marketed; consult the product label.


For adjunctive treatment of chronic pain:

1. Glucosamine/chondroitin: 13-15 mg/kg (of the chondroitin component) PO once daily (q24h). (Hardie, Lascelles et al. 2003)

For adjunctive treatment of cancer pain:

1. Glucosamine/chondroitin: 15-30 mg/kg (of the chondroitin component) PO once daily (q24h) for 4-6 weeks than half the dose. (Lascelles 2003)

For adjunctive treatment of chronic pain:

1. Glucosamine/chondroitin: 13-15 mg/kg (of the chondroitin component) PO once daily or every other day (q24-48h). (Hansen 2003b)

I don't think you are giving enough. I have a 48# Springer with 'sports injuries' to her knees. I use 'Synflex', a liquid form. The bottle says 1/8 tsp but I give 1/4 tsp daily and it works for her.

I tried going to a cheaper brand but upon closer examination it was weaker so we went back to Synflex. I swear by it. She's 12 and has been using it for almost 5 years.

best of luck.

I found a product that has worked well for us, it was recommended by our vet for our two older Lhasa Apsos. They have both shown improvement since I added it to their diet.

It's called Synovi G3
Here is the ingredients & dosage information:


SynoviG3 Product Information

SynoviG3 contains MethylSulfonylMethane(MSM), to alleviate discomfort associated with systemic inflammatorydisorders. Supplementation with MSM can result in the relief pain andstiffness along with reduced swelling and inflammation. MSM preventspressure buildup in cells, allowing nutients in and toxins out.

Well... the information didn't cut & paste very well, sorry. There are other manufacturers of products made specifically for dogs so you might want to do some research.

At one time our resident forum vet/moderator Dr. Doug was giving his dog Megan Synovi G3. He might some insight to this particular product. It works well for us.

I just started Charlie on Synovi G3. I think it's a good product.

Thank you everyone for posting this info. The glucosamine treats that worked for my kitty are now tough on her sensitive tummy (additives and artifical stuff maybe?) and she cannot keep it down.

So I will try something else. This was helpful!
