Signs of Arthritis in Dogs: What to Look For and What to Do Next

If your dog has started to hesitate before the car boot, or sleeps in a different spot than they used to, arthritis is worth raising with the vet. The signs are often quiet, and dogs are good at carrying on. Many owners put early changes down to age, and many vets would rather see a dog with mild signs than hear later that it had been struggling for a long time. This is general information, and only a vet can diagnose what is going on.
The signs that are easy to miss
Obvious limping is a late sign for many dogs. Earlier on, look for patterns like these.
| What you notice | Where you might see it |
|---|---|
| Slow to get up after rest, then loosens up | First minutes of a walk, after a nap |
| Hesitating or refusing jumps | Car, sofa, bed |
| Taking stairs one at a time or avoiding them | Home, garden steps |
| Shorter walks, lagging behind, sitting down mid-walk | Familiar routes |
| Less interest in play or fetch | Garden, park |
| Licking or chewing at a joint | Wrists, hocks, hips |
| Sitting awkwardly, with legs out to the side | Waiting, feeding |
| Slipping on hard floors | Kitchen, hallway |
| Grumpiness when touched or approached | Being stroked, being lifted |
| Thinner thigh or shoulder muscles | Visible when standing |
None of these proves arthritis. Each can have other causes, including injury, ligament problems, infections or, for the grumpiness, simply a bad day. What matters is a pattern that persists or gets worse.
Changes in behaviour are easy to misread. A dog that stops greeting you at the door, or becomes snappy about its bed, may be in discomfort rather than being difficult. Older dogs are not the only ones affected, either, since joint trouble can follow injury or developmental problems in younger dogs, and larger breeds are commonly said to be more prone.
Make a record before you go
Vets see dogs in a strange room on a short visit, and a dog on adrenaline can walk perfectly. Take a few short phone videos of your dog getting up, walking on a hard floor and tackling stairs. Note when stiffness is worst, how long walks are, and any change in appetite. That record gives the vet more to work with than a verbal description.
What the vet will do
Expect a physical examination, including feeling and flexing joints and watching your dog walk. The vet may suggest imaging, such as X-rays, and blood tests where medication is being considered. Diagnosis is the point: stiffness can have different causes that need different handling, and some of them are treatable in ways that supplements cannot address.
Pain management is a vet decision
Vets can prescribe pain relief and anti-inflammatory medicines made for dogs, and in some cases suggest other options. These involve checks and monitoring, and they are not interchangeable with anything in the human medicine cabinet. Never give your dog human painkillers unless the vet has told you to, because several common ones are dangerous to dogs.
Where supplements and home changes fit
Supplements are an optional extra that some owners try alongside veterinary care. The evidence is mixed, and we explain why in do dog joint supplements actually work. If you want to compare products, best joint supplements for dogs covers the options, and the vet can tell you whether one is sensible alongside any medication.
Home adjustments tend to deliver more: non-slip rugs on hard floors, a thick supportive bed, a ramp for the car, steady shorter walks, and above all a healthy weight. Extra body weight puts extra load on sore joints, and losing some is one of the most widely recommended steps. Our guide to helping a stiff senior dog at home walks through these changes.
Why dogs hide it
Dogs rarely show pain the way people do. They tend to adapt: they sleep more, walk less, choose the flat route and stop asking for the things that hurt. Because the change is gradual, owners who see the dog every day often notice it last, and it is relatives or friends who have not visited for a while who say your dog looks stiffer. Take that kind of comment seriously. A casual remark from someone who has not seen the dog for six months is a useful second pair of eyes.
When it cannot wait
Ring the vet the same day if your dog suddenly cannot put weight on a leg, cries out when touched or moved, is unable to get up, has a hot or swollen joint, stops eating, or seems distressed. Those signs are not the slow creep of arthritis, and they need prompt attention.
Common mistakes
The usual ones are waiting to see whether it passes, assuming it is just old age, pushing a stiff dog through a long walk to loosen it up, and starting a supplement without having had the diagnosis. Dogs with arthritis tend to do better with a plan: a diagnosis, a vet-led approach to pain, a lean body, sensible exercise and a home that is easier to move around in.
