How Do I Know If My Dog Is in Pain?

By the Woofio Team · Updated September 2026 · 7 min read

Most owners do not spot pain. They spot a change. The dog who used to meet you at the door now waits on his bed. The one who jumped into the boot in one go now puts a paw up first and thinks about it.

Those small edits to daily life are usually the first and only warning you get, because a dog's instinct is to hide weakness. This guide covers the twelve signs owners most often miss, which of them point towards the joints, and when a change is worth a call to the vet.

Why Dogs Hide Discomfort

In the wild, an animal that looks injured becomes a target. Dogs kept that instinct. A dog will keep walking, keep eating and keep greeting you long after something has started to bother him, because doing otherwise runs against thousands of years of wiring.

This is why owners so often say the same thing at the vet: it came on suddenly. It rarely did. It became visible suddenly, which is a different thing. By the time a dog limps openly, the change has usually been building for weeks or months.

That is not a reason to panic. It is a reason to watch the small stuff.

The 12 Signs Owners Most Often Miss

Changes in how he moves

• He hesitates before jumping. The sofa, the bed, the boot of the car. Not refusing, just pausing. This is often the very first sign.
• Stairs became a decision. He takes them one at a time, or waits at the bottom to see whether you are really going up.
• He is stiff after resting. The first few minutes out of the basket look laboured, then he loosens up. Owners tend to read this as normal ageing. It is worth noting.
• Walks got shorter without you deciding that. He turns for home earlier, or lags on the way back rather than the way out.
• He sits down differently. Flopping onto one hip, or sliding down instead of lowering himself.

Changes in how he behaves

• He is less patient. A grumble when a child leans on him, or when he is moved off the sofa. In a dog who was never grumpy, that is information.
• He withdraws. Choosing the quiet room over the busy one. Sleeping somewhere new.
• He is restless at night. Getting up, circling, resettling. Discomfort tends to show most when there is nothing else to focus on.
• He has stopped asking. No more bringing the lead, no more nudging for the ball. Owners often read this as the dog "calming down with age".

Changes you can see on his body

• He licks one particular spot. Often a wrist, a hock or a hip. Repeated licking in one place is worth showing your vet.
• One side looks smaller. Muscle builds where a dog puts weight and fades where he avoids it, so an uneven back end often reflects an uneven load.
• He pants when he is not warm and not excited. Panting at rest, in a cool room, is a signal that gets overlooked more than almost any other.

Which Signs Point Towards the Joints

Not every change is a joint change. This is a rough guide to what tends to point where, and it is a starting point for a conversation with your vet rather than a substitute for one.

The pattern that most often points at the joints is the combination of stiffness after rest, reluctance around height, and worse days after bigger days. One of those on its own means little. Three together is a pattern.

What to Do This Week

Before you change anything, spend seven days watching. Vets get a much better picture from a week of small notes than from a description given under the stress of an appointment.

At the end of the week you will either see nothing, which is genuinely reassuring, or you will see a pattern that is far easier to describe than "he has just slowed down a bit".

When to Call Your Vet

For the slower changes, book a routine appointment and bring your week of notes. Ask specifically about mobility rather than only about pain, because "is he in pain?" is a harder question for anyone to answer than "has this got worse since spring?".

What Helps Day to Day

Whatever your vet advises, a few things are worth doing regardless, because they reduce the load on ageing joints without asking anything of your dog.

• Shorter, more often. Two twenty-minute walks are usually kinder than one long one.
• Take the height out of the day. A ramp to the car and a step to the sofa remove the two moments most dogs find hardest.
• Grip underfoot. Runners across polished floors stop the constant small slips that tire a dog out.
• Weight. The single biggest lever there is. Every extra kilo is carried by the same joints, every step of every day.
• Warmth after exercise. A dry bed away from draughts, especially in winter.
• Daily joint support. A supplement that supports joint health is a long game rather than a quick fix, and it works best started before things get difficult rather than after.

Common Questions

How can I tell if my dog is in pain or just getting old?

Healthy ageing is gradual and fairly even. Discomfort tends to be uneven: better on some days, clearly worse after a long walk or on a cold morning. If the good days and bad days differ noticeably, that is worth mentioning to your vet.

Do dogs cry when they are in pain?

Usually not. Vocalising tends to come with sudden, sharp problems. Slow-building discomfort almost always shows up as changed behaviour instead, which is why it is so easy to miss.

At what age should I start thinking about my dog's joints?

Earlier than most people do. Large and giant breeds are usually considered mature well before smaller dogs, and dogs who are very active, or who carry extra weight, put more through their joints throughout life. Your vet can tell you where your dog sits.

Can I give my dog human painkillers?

No. Several common human medicines are dangerous to dogs, including some available without a prescription. Never give anything from your own cabinet. If your dog needs medication, that is a decision for your vet.

How long does a joint supplement take to work?

Joint supplements are cumulative rather than immediate. Give any product a fair run of several weeks alongside the practical changes above, and judge it on the small things: the first five minutes of the day, and whether height is still a decision.
