Pain is stressful and harmful, and dogs often hide it as an instinct. Learning to spot subtle signs lets you help sooner.

Behavior changes

• Reduced activity or slowing down
• Reluctance to play, jump, climb stairs or get in the car
• Irritability, snapping or growling when touched
• Hiding or withdrawing
• Restlessness or difficulty settling at night
• Excessive sleeping
• Changes in toileting, such as accidents
• Reduced appetite

Physical signs

• Limping or stiffness. See why is my dog limping
• Hunched back or tucked belly
• Head held low
• Panting at rest
• Trembling or shaking
• Licking or chewing a body part
• Muscle loss
• Squinting eyes
• Dilated pupils
• Fast breathing

Facial expressions

A pained dog may have a tense face, furrowed brow, squinted eyes, a glazed look and ears held back or flattened. Compare with his normal expressions. See dog body language guide.

Common causes

• Arthritis and joint disease. See arthritis in dogs
• Dental disease. See dental disease in dogs

• Back and neck problems. See intervertebral disc disease in dogs
• Injuries and wounds
• Abdominal conditions, such as pancreatitis and blockages
• Cancer
• Eye problems. See corneal ulcers in dogs

Why dogs hide pain

In the wild, showing weakness can be dangerous. Many dogs, especially stoic breeds, hide pain until it is severe. Some behaviors that owners assume are aging or bad attitude are actually pain.

When to see a vet

Book an exam if you notice behavior or mobility changes lasting more than a few days, or sooner if your dog yelps, refuses to move or shows severe signs. Seek urgent care for sudden severe pain, abdominal swelling or inability to stand.

How vets assess pain

Vets use a thorough exam, observe movement, check joints and the spine and may use pain scoring tools. They may recommend imaging, bloodwork and a trial of pain relief. Videos of your dog at home help.

Treatment options

• Veterinary-prescribed medication: NSAIDs, gabapentin and others. See NSAIDs and pain medication for dogs
• Treating the underlying cause
• Physical therapy, acupuncture and hydrotherapy
• Weight management
• Home modifications
• Supplements as advised

Do not give human painkillers. See why human painkillers are dangerous for dogs.

Helping your dog at home

1. Provide soft, supportive bedding.
2. Use ramps and non-slip surfaces.
3. Keep a pain diary.
4. Handle gently.
5. Follow medication instructions.

Questions to ask your vet

Ask how to tell whether pain is controlled, which medications suit your dog, what side effects to watch and how often to recheck blood tests.

Common mistakes

• Assuming slowing down is age
• Using human painkillers
• Ignoring behavior changes
• Stopping medication early

Troubleshooting

• My dog snaps when touched: assume pain and see your vet.
• My dog pants at night: consider pain and book a check.
• My dog is stiff only after rest: discuss arthritis.

A simple plan

1. Watch for subtle signs.
2. Record changes.
3. See your vet.
4. Follow a pain plan.

Real-life examples

A spaniel that stopped jumping on the couch has a bad tooth. A shepherd's snappiness resolves after arthritis treatment. A terrier's night restlessness leads to a diagnosis of a back problem. Pain explains many changes.

Listening to your dog

Small changes matter. Trust your instincts.

Keeping a pain diary

Rate your dog's mood, willingness to walk, stiffness, appetite and sleep from one to five each day, and add notes about weather and activities. Over weeks a pattern emerges, and your vet can see whether treatment is working. Short videos of walking and rising from bed are especially useful.

Pain in particular breeds and ages

Stoic breeds and some senior dogs hide discomfort particularly well. Puppies can have growing pains and injuries, while seniors often live with arthritis and dental pain unnoticed. Regular checkups, at least yearly and twice yearly for seniors, give your vet a chance to find hidden pain early.

The takeaway

Dogs hide pain. Notice subtle changes and see your vet for safe relief.
