Glucosamine is widely used in dogs and cats for joint support and is safe at recommended supplement doses. Use pet-specific products — human glucosamine supplements may contain xylitol. Consult a veterinarian for dose and product guidance.
Glucosamine is a naturally occurring compound found in cartilage and joint fluid, produced commercially from shellfish shells (glucosamine hydrochloride or sulfate) or via fermentation.
Sold as chewable tablets, soft chews, powders, and liquids formulated for pets. Also found in commercial joint diets and over-the-counter joint health chews.
Natural food sources include beef trachea (safe as a supervised chew), pork tails, and pig ears. For poultry sources like chicken feet and turkey necks, simmer into broth and offer only the strained, bone-free liquid — do not offer poultry bones as direct chews.
