Do Dog Joint Supplements Really Work? Here’s What You Should Know

Jun 24, 2025Jasmine Lin

As dogs age—or even in their prime—joint health can have a major impact on quality of life. Whether it’s your sprightly spaniel slowing down or a large breed showing early signs of stiffness, dog joint supplements are an increasingly popular way to support mobility, flexibility, and comfort.

Why Do Dogs Need Joint Support & Dog Joint Care 

Joint issues in dogs are surprisingly common. Conditions like osteoarthritis, hip dysplasia, or general wear and tear can lead to reduced mobility, stiffness, and pain. While certain breeds are genetically predisposed, factors like weight, lifestyle, and age all play a role.

Joint supplements aim to nourish the cartilage, support fluid in the joints, and reduce inflammation—giving your dog a better chance to stay active and comfortable.

Key Ingredients to Look For

Glucosamine

This naturally occurring compound is one of the most popular ingredients in dog joint supplements. It supports the repair of cartilage and can help slow the progression of joint degeneration.

Chondroitin Sulphate

Often paired with glucosamine, chondroitin helps cartilage retain water, improving its elasticity and shock-absorbing qualities. Together, these two can offer synergistic benefits.

MSM (Methylsulfonylmethane)

MSM is known for its anti-inflammatory properties. It also supports the formation of collagen, which is vital for healthy joints, skin, and connective tissue.

Omega-3 Fatty Acids (see our Omega 3 for dogs article) 

Derived from fish oil or algae, omega-3s help reduce inflammation in the joints. They may also provide cardiovascular and cognitive benefits, making them a well-rounded addition to a supplement.

Turmeric (Curcumin)

This natural anti-inflammatory has become popular for its potential to reduce pain and swelling. It’s often included in more holistic or plant-based joint supplements.

Hyaluronic Acid

Important for joint lubrication, hyaluronic acid helps maintain synovial fluid viscosity. Some premium formulas include this to promote smoother joint movement.

When to Start Your Dog on a Joint Supplement

Many vets recommend starting large-breed dogs or very active breeds on joint support supplements as a preventative measure—even from as early as one year of age. For older dogs, especially those showing signs of stiffness or reluctance to move, supplements can be a supportive part of their care plan.

Choosing the Right Supplement

There’s a growing range of products on the market, so finding the right one means looking beyond the label. Here’s what to consider:

  • Ingredient transparency: Look for brands that fully disclose their active ingredients and dosages.
  • Form: Powders, chews, and liquid formulas each have their pros—go with what your dog prefers.
  • Clinical support: Products backed by veterinary studies or real-world reviews can offer peace of mind.
  • No fillers: Avoid unnecessary binders, artificial flavourings, or sugar that might upset your dog’s stomach.

Signs Your Dog Might Benefit from Joint Support

  • Stiffness when getting up or lying down
  • Reluctance to jump, run or climb stairs
  • Limping or favouring one leg
  • Reduced activity or interest in walks
  • Noticeable joint swelling or discomfort

While supplements aren’t a cure, they can be an effective part of a broader plan to support your dog’s health and mobility. Always consult your vet before starting a new supplement—especially if your dog is already on medication or has a chronic condition.
