Why Joint Supplements for Dogs Matter
If your dog has arthritis, joint supplements may help provide some relief from pain, says Dr. Erin Miscioscia, clinical assistant professor of integrative and mobility medicine at the University of Florida College of Veterinary Medicine.
However, not all joint supplements are equal, and research on which ingredients provide the biggest benefits is quite limited. Dr. Duncan Lascelles, director of the Comparative Pain Research and Education Center at North Carolina State University College of Veterinary Medicine, notes that marine-based omega-3 fatty acids are the one compound known to help relieve joint pain in dogs.
5 Vet-Recommended Joint Supplements for Dogs
Best Overall: Nordic Naturals Omega-3 Pet
This fish oil supplement is the best all-around option and comes recommended by one of the veterinarians we spoke with. Studies show anti-inflammatory omega-3 supplements deliver the most pain relief to osteoarthritic dogs compared to other active ingredients.
- Made with omega-3 fish oil from four marine sources: anchovy, sardine, mackerel, and herring
- Certified by the National Animal Supplement Council (NASC)
- Third-party lab tested to verify purity
- Lacks the fishy smell and taste that some dogs find unappealing
Note: Fish oil is safe for all dogs, but too high a dose too quickly can cause diarrhea, so introduce it slowly. It contains 39 kcal per teaspoon — check with your vet for the right dose.
Best Chews: Vetoquinol Flexadin Advanced with UC-II
These chews contain undenatured type-II collagen (UC-II), which helps reduce joint inflammation and may play a role in rebuilding part of joint cartilage. A 2007 study found that UC-II helps decrease osteoarthritis symptoms, reduce lameness, and increase physical activity and mobility.
The chews also contain vitamin E, which may provide anti-inflammatory benefits, and omega-3 fatty acids at lower doses.
Best Tablets: NaturVet Glucosamine DS Plus
This moderate joint care chewable tablet is the top choice in the tablet category for dogs needing glucosamine supplementation.
Best Treats: NaturVet Hip and Joint Advanced
These soft chews combine joint care with the convenience of treats, perfect for maintaining joint health while rewarding your dog.
Best Powder: Wholistic Pet Organics Joint Mobility GLM
This enhanced multivitamin powder is ideal for dogs whose owners prefer mixing supplements into food, providing comprehensive joint mobility support.
Tips for Choosing Joint Supplements for Your Dog
If your dog shows signs of joint pain from arthritis, an injury, or an unknown condition, the first step is to speak with your veterinarian. Before purchasing any supplement, ask your vet whether they're the right choice for your dog's unique needs.
Additionally, Dr. Miscioscia emphasizes that maintaining a healthy weight is the most critical factor in managing arthritis in dogs. Supplements are just one part of a comprehensive management plan — proper diet and moderate exercise are equally important.
