Ingredient highlights
Glucosamine for dogs is a key building block of joint cartilage, helping maintain healthy cartilage structure and normal joint lubrication. It supports the body’s natural repair processes to cushion joints and ease everyday stiffness from activity and aging. Consistent use promotes comfortable mobility and flexibility so dogs can move more easily.
Chondroitin helps keep joint cartilage hydrated and springy, improving shock absorption with every step. It supplies key building blocks for proteoglycans while helping limit enzymes that break down cartilage. Used with glucosamine, it supports comfortable mobility and healthy joint function in active and aging dogs.
Each Serving Size (1 wafer) contains: Ingredients: Glucosamine sulfate (from shellfish), chondroitin (as chondroitin sulfate), ginger (root), honey, bovine liver, ascorbic acid, calcium stearate, d-alpha tocopherol (vitamin E sunflower), modified tapioca starch, and turmeric (root) powder.
Research on glucosamine and chondroitin for dog joint healt
Glucosamine (for dogs):
Glucosamine supplies raw material for glycosaminoglycans and proteoglycans—the “cushion” inside cartilage—supporting joint lubrication and structural repair. In client-owned dogs with hip/elbow OA, a randomized double-blind trial (n=35) found an oral glucosamine HCl + chondroitin combo significantly improved veterinarian-scored pain, weight-bearing, and overall severity by about 10 weeks, albeit with slower onset than carprofen. Newer block-randomized work in 75 dogs didn’t see force-plate improvement at 6 weeks with glucosamine/chondroitin vs placebo, suggesting benefits (when they occur) may require a longer run-in and remain modest—consistent with reviews that call the evidence mixed but biologically plausible and generally safe.

Chondroitin (for dogs):
Chondroitin sulfate helps cartilage retain water, supports proteoglycan synthesis, and can down-regulate catabolic enzymes that chew up matrix. In an experimental canine OA model, an oral chondroitin + glucosamine + manganeseregimen shifted synovial fluid 3B3/7D4 epitopes—biomarkers consistent with enhanced cartilage matrix metabolism—supporting a chondroprotective effect; and in client-owned dogs, the glucosamine/chondroitin combo improved clinical scores by ~10 weeks in an RCT. Contemporary veterinary reviews judge effects as possible but variable across trials (small when present), with a favorable tolerability profile. PubMed+1MDPI
