The main signs of arthritis in dogs are stiffness after rest, slowing down on walks, reluctance to jump or use stairs, limping, licking a sore joint, trouble squatting to toilet and grumpiness when touched. Early signs are often behaviour changes rather than a limp, so book a vet check as soon as you notice them.
Many owners wait for a limp, but by then the joint has often been sore for a while. Spotting arthritis early is one of the best ways to protect your dog's comfort, mobility and quality of life.
What is arthritis in dogs?
Arthritis in dogs, usually osteoarthritis, is a long-term joint disease that causes pain and inflammation. The smooth cartilage that cushions the ends of the bones slowly breaks down. As it wears away, the joint becomes rough and sore, and movement becomes harder.
- It gets worse over time.
- It most often affects the hips, elbows, knees (stifles) and spine.
- It causes ongoing pain and inflammation.
- Treatment focuses on comfort and slowing it down.
It is often called a wear-and-tear disease. It is most common in older dogs, but younger dogs can get it after an injury or because of a joint that did not develop properly, such as hip or elbow dysplasia.
What are the 7 main signs of arthritis in dogs?
The seven main signs of arthritis in dogs are stiffness, reluctance to move, limping, licking joints, trouble toileting, muscle loss and changes in temperament. Not every dog shows all of them, and they usually creep in slowly.
1. Stiffness, especially after rest
This is the classic early sign. Your dog may be stiff when they first get up from a nap or in the morning, and take a few minutes to warm up. Stiffness after rest is a hallmark of joint pain, and cold, damp weather often makes it worse.
2. Reluctance to move or play
A dog that once loved fetch but now watches the ball go by, or suddenly avoids the stairs or the car, is often telling you something hurts. This is not laziness. They are avoiding movements they know will be painful.
3. Limping or lameness
The limp may be subtle at first, perhaps only after a long walk or a hard play session. It may affect one leg or several. As arthritis progresses, the limp usually becomes more constant.
4. Licking, chewing or biting at joints
Dogs often lick a sore spot to soothe it. If your dog keeps licking a wrist, knee or paw, it can point to discomfort underneath. You may see reddish-brown saliva staining on the fur there.
5. Trouble squatting to toilet
This early sign is often missed. Squatting needs flexible hips and knees. A dog with arthritis may struggle to hold the position, have accidents indoors, or go out less often.
6. Muscle wasting
If a dog favours one leg, the muscles on that leg shrink from lack of use. You might notice one thigh looks thinner than the other. This usually means the problem has been there for a while.
7. Changes in temperament
Pain changes behaviour. A sweet-natured dog may become grumpy, irritable or snappy when touched. They may withdraw from the family or seek more time alone. This is often mistaken for "just getting old", but it is frequently a response to ongoing pain.
What are the signs of arthritis in a dog's back legs and hips?
Signs of arthritis in a dog's back legs and hips include struggling to stand up, a swaying or narrow walk, "bunny hopping" with both back legs together when running, and sitting slightly to one side. Your dog may also be reluctant to jump into the car or climb stairs, and the thigh muscles may look thinner.
Signs of arthritis in the hind legs often show most when your dog first gets up, then ease a little once they warm up.
What are the signs of arthritis in a dog's front legs and paws?
Signs of arthritis in a dog's front legs include a short, choppy stride and a head that bobs up as the sore leg lands. Dogs often take more weight on the back legs to spare the front. Elbows are a common site, especially in large breeds.
Arthritis can affect the paws too. The toe joints may look swollen or thickened, and your dog may lick their front paws more than usual. Paw licking has many causes, including allergies, so ask your vet to look.
What are the signs of arthritis in a dog's back?
Arthritis in the spine often shows as a hunched or stiff back, reluctance to turn or look up, and trouble getting comfortable to lie down. Some dogs flinch when stroked along the back or struggle to shake off after a swim. Spinal pain can also be caused by disc problems, which can be serious, so get it checked promptly.
Can arthritis symptoms come on suddenly in dogs?
The disease develops slowly, but the signs can appear suddenly. A flare-up often follows a minor knock, a burst of over-exercise, or a change in weather. The arthritis was likely already there, and the event tipped the joint into obvious pain.
A sudden, severe lameness, a dog who will not put a leg down, or a dog who cannot stand needs a vet the same day, as an injury such as a ligament tear may be the cause.
How do vets diagnose dog arthritis?
Vets diagnose dog arthritis with a hands-on examination and, usually, X-rays. Other conditions can cause similar signs, so symptoms alone are not enough.
First comes a full physical and orthopaedic check. Your vet will watch your dog walk and trot, then gently feel and flex the joints for pain, swelling or reduced movement.
If arthritis is likely, X-rays show the changes inside the joint, such as bony spurs and narrowing of the joint space. A structured pain assessment is an important part of good arthritis care.
How can I help my dog with arthritis at home?
You can help your dog with arthritis at home by keeping them lean, adjusting exercise and making the house easier to move around. Your vet may prescribe pain relief, but home care makes a big difference alongside it.
- Weight control: the single most important factor. Extra weight puts huge strain on sore joints.
- Home changes: use non-slip rugs on laminate or tiles, add ramps for the car or sofa, and raise food bowls for stiff necks.
- A good bed: a thick orthopaedic or memory foam bed for a dog with arthritis spreads weight and eases pressure on joints. Keep it away from draughts.
- Controlled exercise: short, regular lead walks keep muscle without overloading joints. Hydrotherapy is a good low-impact option.
Does cold weather make arthritis worse in dogs? Many owners notice more stiffness in cold, damp spells. A coat for short-haired dogs, a warm bed and a gentle warm-up walk all help.
Myth: a dog with arthritis should be rested as much as possible. Too much rest weakens the muscles that protect the joints. Gentle, regular movement is better than either long hikes or none at all. A multimodal approach combining lifestyle, diet and medication is one of the most useful ways to support dogs with arthritis.
What are the best supplements for dogs with arthritis?
The best supplements for dogs with arthritis combine several joint ingredients rather than relying on one. Many dog arthritis supplements offer only glucosamine. As an MRCVS-registered vet, I think that rarely reflects how complex joint disease is, as it involves cartilage, inflammation and muscle.
Glucosamine is a natural building block of cartilage and may help support its structure. The evidence is mixed, and benefits tend to be modest and gradual, as reviews of glucosamine and chondroitin in canine osteoarthritis point out. It works best as part of a broader blend.
Juno Daily joint support includes glucosamine and chondroitin for cartilage, and omega-3 DHA to help support a healthy inflammatory response. It also contains L-carnitine for dogs to support lean muscle, which helps steady weak joints, plus prebiotics and probiotics for the gut. You can read the reasoning in the science behind Juno's formula.
Supplements, whether arthritis tablets for dogs or powders, are support, not a cure. Most dogs do best when they sit alongside weight control, exercise changes and vet pain relief where needed, and results vary between dogs.
Can you prevent arthritis in dogs?
You cannot always prevent arthritis, especially when genes or an old injury are involved, but you can help delay it and reduce its severity. The most powerful tool is keeping your dog lean throughout life, which reduces daily strain on the joints.
Sensible exercise, and joint support before obvious signs appear, may also help. No supplement can guarantee prevention, but a lean body and strong muscles give the joints the best start.
Key takeaway: keeping your dog lean is the single best thing you can do for their joints at any age.
When should I see a vet for my dog's stiffness?
See a vet at the first sign of change, rather than waiting for a constant limp. Hesitating at the stairs, grumpiness, or seeming "off" in the mornings are all good reasons to book a check.
The earlier a plan starts, the more can be done to slow arthritis down and keep your dog comfortable. If you want daily joint support alongside your vet's plan, have a look at Juno Daily.
Frequently asked questions
How do you know if your dog has arthritis?
Watch for stiffness after rest, slowing on walks, reluctance to jump, licking joints or grumpiness when handled. A vet confirms it with an examination and usually X-rays, as other problems can look similar.
Is my dog in pain with arthritis?
Yes, arthritis is painful. Signs of pain include limping, stiffness, irritability, restlessness at night and licking a sore joint. Any clear change in movement or behaviour deserves a vet check.
At what age do dogs usually get arthritis?
It is most common in dogs over seven or eight years old, but it can affect dogs at any age. Younger dogs may develop it after a joint injury or because of hip or elbow dysplasia.
Does walking make dog arthritis worse?
The wrong kind can. Long, high-impact hikes or frantic ball chasing can cause a flare-up. Short, regular lead walks help, because they keep the muscles that support the joints strong. Little and often is the rule.
What's the difference between arthritis and hip dysplasia?
Hip dysplasia is a developmental problem where the ball and socket of the hip do not fit properly. That loose joint wears unevenly, which leads to arthritis. Dysplasia is the cause, and arthritis is the painful result.
Can I give my dog human painkillers for arthritis?
No. Never give human medicines such as ibuprofen or paracetamol, which can cause serious kidney, liver or stomach damage in dogs. See our guide on whether ibuprofen is safe for dogs, and ask your vet for dog-safe pain relief.
What is the best food for a dog with arthritis?
The best food is one that keeps your dog lean, as weight control matters most. Some vet joint diets add omega-3s, glucosamine and chondroitin. Your vet can recommend a suitable plan for your dog.
Are some dog breeds more prone to arthritis?
Yes. Large and giant breeds such as Labradors, Golden Retrievers, German Shepherds and Rottweilers carry a higher risk, as do breeds prone to joint or spine problems. Keeping these dogs lean is especially important.
