Dogs in pain rarely cry out. Yelping is the exception, not the rule. The reliable signals are behavioural: a dog that stops jumping onto the sofa, sleeps in a new position, licks one spot repeatedly, eats more slowly, or snaps when touched in a place it never minded before. Chronic pain in particular shows up as a change in habits, not as drama.
The short answer
- Pain in dogs usually looks like a change in normal behaviour, not vocalising.
- The most common early signs are reluctance to jump or climb stairs, licking one area, and changed sleep or posture.
- Sudden severe signs, a distended abdomen, or unproductive retching are emergencies.
- Never give human painkillers. Ibuprofen and paracetamol are toxic to dogs.
- A written record of when a change started is the single most useful thing you can bring to a vet.
9 signs your dog is in pain
1. Reluctance to jump, climb stairs or get up
Often the first sign of joint pain, and often misread as ageing. A dog that hesitates before the car boot, takes stairs one at a time, or needs a moment to rise after lying down is usually telling you something hurts. Dogs do not slow down simply because they had a birthday.
2. A changed posture or gait
Watch from behind as your dog walks away. Shifted weight, a shortened stride on one side, a hunched back, a tucked abdomen, or a lowered head carried differently than usual all point to pain. The classic praying position, chest down and rear up, frequently signals abdominal pain.
3. Licking, chewing or scratching one spot
Dogs groom pain. Persistent attention to a single joint, paw or flank is worth investigating, particularly when it creates a wet, stained or bald patch. The skin damage is a consequence, not the cause.
4. Changes in sleep
Both directions matter. A dog that sleeps much more than usual may be conserving energy; a dog that cannot settle, changes position repeatedly, or paces at night is often uncomfortable lying down. A new preference for the hard floor over a soft bed can indicate joint or back pain.
5. Loss of appetite or slower eating
Dental pain is one of the most under-recognised sources of chronic discomfort. Signs include dropping food, chewing on one side, approaching the bowl eagerly then backing off, or a sudden preference for soft food.
6. Irritability, or withdrawal
A gentle dog that growls when lifted, or a sociable dog that starts spending the day in another room, has usually not changed personality. Pain shortens a dog's tolerance in exactly the way it shortens ours.
7. Heavier panting unrelated to heat or exercise
Panting on a cool day, at rest, or overnight is a recognised pain signal. It is easy to dismiss because panting is such normal dog behaviour, so the context is what matters.
8. Trembling, restlessness or an inability to settle
Shaking that is not cold and not fear frequently accompanies pain. So does the pattern of lying down, standing up, circling and lying down again.
9. Changes in toileting
Straining, an altered posture while toileting, accidents in a previously reliable dog, or reluctance to squat can all reflect pain in the back, hips or abdomen rather than a training or urinary problem.
Signs that mean call a vet today
Some presentations are not a wait-and-see situation. Seek veterinary attention immediately for:
- A distended or hard abdomen, especially with unproductive retching, which may indicate bloat and gastric torsion
- Sudden inability or refusal to bear weight on a limb
- Sudden hind-limb weakness, dragging paws or loss of coordination
- Pale gums, collapse or laboured breathing
- Crying out on touch or movement
- Any severe sign that appears within hours rather than weeks
Why dogs hide pain
This is not stoicism as a personality trait. Concealing weakness is adaptive behaviour inherited from animals for whom visible injury attracted predators and lost social standing. The result is that by the time a dog shows obvious pain, the underlying problem is often well established.
It also means the absence of complaint proves nothing. Dogs with significant arthritis frequently still greet visitors, chase a ball for two minutes, and eat dinner. Willingness to do something a dog loves is a poor test of whether it hurts.
Never give human painkillers
This deserves its own warning. Ibuprofen and other human anti-inflammatories cause stomach ulceration and kidney damage in dogs at doses close to a normal human tablet. Paracetamol, also sold as acetaminophen, damages the liver and red blood cells. Aspirin is not a safe substitute either. Every year clinics treat dogs poisoned by an owner trying to help between appointments.
If your dog is in pain outside clinic hours, call an emergency service and ask. Do not improvise from the bathroom cabinet.
How vets assess pain
Veterinary pain assessment is more structured than most owners expect. Clinics use validated scoring tools alongside a hands-on examination, and the 2022 AAHA Pain Management Guidelines and WSAVA pain guidelines set out the standard approach for dogs and cats.
What a vet cannot do is observe your dog at home over six weeks. That part is yours, and it is often the part that identifies the problem.
Track the change, not just the moment
The most useful thing an owner brings to an appointment is a timeline: when the behaviour started, how often it happens, whether it is worse in the morning or after exercise, and what has changed since. A vague sense that the dog has been off for a while is much weaker evidence than a dated list.
PetVitals is built for exactly this. Log a symptom with a severity level and a date, record weight over time, and the pattern becomes visible rather than remembered. Weight loss alongside behavioural change is worth watching closely; for cats, our cat weight chart by breed explains what normal looks like. If you are caring for a young dog, the puppy vaccination schedule covers the other half of early health planning.
