If your dog has stiff joints, you’ve probably come across glucosamine for dogs in one way or another. Joint supplements are amongst the most widely used nutritional supplements today, and most of these are built primarily around glucosamine and chondroitin. Your vet may even recommend trying a supplement with glucosamine for dogs to support your pet's joints before considering medical treatments.
Alongside these two key nutrients there are many other ingredients used in the various joint supplements for dogs – curcumin (from turmeric), MSM, hyaluronic acid, omega-3 fatty acids, vitamin C, minerals and herbal extracts to name a few.
