Why joint support matters for senior dogs
As dogs age, cartilage wears down and everyday movement gets harder. The right joint supplement can ease stiffness and help your dog stay active.
What to look for
- Glucosamine and chondroitin as the core ingredients.
- Omega-3 (EPA/DHA) to help with inflammation.
- A dose matched to your dog's weight.
How to choose
Start with a well-reviewed option for your dog's size, and give it 4-6 weeks to take effect.
