This guide is for general information and is not veterinary advice. Always talk to your veterinarian about your dog’s health.
Large and giant breeds such as Labradors, German Shepherds, Golden Retrievers and Great Danes put far more load on their hips, elbows and knees, and many are prone to hip and elbow dysplasia. A joint supplement can be part of a sensible plan, but big dogs need the right dose, and many chews are sized for much smaller dogs. We have not tested these products hands-on; our picks are based on published ingredient labels, the research on each ingredient and owner feedback. Always ask your veterinarian before starting a supplement, especially if your dog takes medication or has a health condition.
What large dogs need from a joint supplement
- Enough of each ingredient per chew. A 90 lb dog may need 3 to 4 small-breed chews to reach the label dose. Large-breed formulas save money and treats.
- A real omega-3 dose. EPA + DHA from fish oil has the best evidence for arthritis, and big dogs need large amounts. Most chews do not come close, so plan a separate fish oil with your vet.
- Shellfish-free options if your dog has an allergy (glucosamine and green-lipped mussel are usually shellfish-derived).
- Quality signals, such as the NASC Quality Seal and clear milligrams per chew.

Dosing by weight
Commonly cited glucosamine guidelines are about 1,000 mg per day for dogs of 45 to 90 lb and about 1,500 mg for dogs over 90 lb, often with a higher loading dose for the first weeks. Follow the label of the product you choose and your vet’s advice. Our glucosamine guide has the full chart.
Start early, but not too early
For growing large-breed puppies, the most important joint protection is the right large-breed puppy food, slow growth and avoiding too much high-impact exercise. Ask your vet before giving joint supplements to a puppy. Many owners start supplements in middle age or at the first sign of stiffness.
Beyond supplements
- Keep your dog lean: extra weight is the biggest avoidable stress on large joints.
- Use a ramp for the car instead of letting a big dog jump out of an SUV.
- Give them a thick, supportive bed.
- Ask your vet to check hips and elbows if you notice stiffness or trouble with jumping.
