Chondroitin sulfate is a neutriceutical used as a supplement for treating canine arthritis[1].

Chondroitin is a peptidoglycan normally found in most connective tissues, especially synovial joints. Chondroitin sulfate is a heterogenous group of compounds that have different molecular masses (15,000-25,000 kDa) and electric change densities[2] and are an essential component of the connective tissue extracellular matrix, including hyaline cartilage and chondroitin provide elasticity and other functions[3].

Age-related loss of production is associated with increased wear and tear radiographic changes associated with arthritis. Oral supplementation has shown to improve joint cartilage repair, although this appears to not be a dose-related response[4].

This drug is not hyperglycemia inducing and is relatively safe to use in dogs with diabetes mellitus[5].

Recommended dose rate in dogs is 5 - 10 mg/kg given orally once daily.
