⚡ Quick answer
Dog arthritis (osteoarthritis) is a long-term joint condition that causes pain and stiffness. Common signs include stiffness after rest, limping, reluctance to jump or climb stairs, and difficulty getting up. It cannot be cured, but vets can reduce pain and slow progression with medication, weight control, gentle exercise and home adjustments. See your vet if you notice these signs and never give human painkillers.
✅ Key takeaways
- Signs are often subtle at first and easy to mistake for “just getting old”.
- Early treatment gives your dog a better chance of staying active and comfortable.
- Weight control is one of the most powerful tools you have.
- Small home changes, like ramps, rugs and a supportive bed, make a big difference.
- Never give ibuprofen, naproxen, paracetamol (acetaminophen) or other human pain relief to a dog unless your vet specifically says so.
What is arthritis in dogs?
Arthritis, usually osteoarthritis, happens when the cartilage that cushions a joint wears down or the joint becomes damaged. Over time this causes inflammation, pain, stiffness and reduced movement. It is common in older dogs, large breeds and overweight dogs, but injuries and joint problems such as hip or elbow dysplasia can lead to arthritis in younger dogs, too.
Signs of arthritis in dogs
The most common signs include:
- Stiffness, especially after resting or first thing in the morning
- Limping or favoring a leg
- Reluctance to jump, climb stairs or get into the car
- Difficulty getting up from lying down
- Less enthusiasm for walks and play
- Weight gain or muscle loss
- Irritability or pulling away when touched
💡 Tip: Take a short video of your dog walking, rising and climbing stairs. It helps your vet see how your dog moves at home, since dogs often hide pain in the clinic.

How vets help dogs with arthritis
There is no cure, but several treatments can ease pain and slow progression. Your vet may recommend a combination.
⚠️ Warning: Human pain medicines such as ibuprofen, naproxen and paracetamol (acetaminophen) can be toxic to dogs. Never give them unless your vet instructs you to. Call your vet or a poison helpline immediately if your dog has swallowed any.

Frequently asked questions
At what age do dogs get arthritis?
It is most common in middle-aged and older dogs, but dogs of any age can develop it, especially after joint injury or with joint conditions such as dysplasia.
How do I know if my dog is in pain?
Look for stiffness, limping, panting at rest, reluctance to move, licking a joint, changes in behavior or irritability. Dogs often hide pain, so mention small changes to your vet.
Are walks good for dogs with arthritis?
Yes. Gentle, regular walks help keep joints moving and prevent weight gain. Avoid overdoing it and follow your vet’s guidance.

Some vets recommend them as part of a plan, but they are not a replacement for veterinary treatment. Ask your vet before giving any supplement.
Should I put my arthritic dog on a diet?
If your dog is overweight, yes. Weight loss can improve mobility and comfort. Your vet can set a safe target and plan.
