How do joint supplements work?

Joint supplements are thought to work by: 

  1. Natural anti-inflammatory action - to soothe stiff joints.
  2. Keep joint fluid healthy - to ease movement.
  3. Feed cartilage - to keep it strong and smooth. 

Joint supplements are useful for some pets but not all - speak to your vet for more information.

Common uses


Joint supplements are thought to slow the progression of arthritis and reduce joint pain. They are safe to use alongside other common arthritis medicines such as anti-inflammatories and pain relief medicines.

Older dogs

Wear and tear throughout life means that joint problems are common in older dogs.

Joint injuries/problems

A joint problem/injury increases the chance of arthritis. Your vet may prescribe joint supplements for your dog if they’ve suffered a joint problem in the past.

Working dogs

Working dogs are at a higher risk of developing arthritis due to the amount of exercise they do. If you own a working dog, your vet may prescribe joint supplements to try to keep their joints healthy.
