How do dogs act when they're in pain?

Pain in dogs usually shows up as behavioral changes rather than obvious signs: increased stillness, reluctance to move or be touched, appetite loss, increased sleeping, or conversely, restlessness and inability to settle. Limping, favoring a limb, and hunched posture are more obvious physical indicators. Many dogs in significant pain won't whimper or vocalize at all.

What should I do if I think my dog is in pain?

If you see multiple signs of pain that are new or getting worse, call your vet. Don't give human pain medications — NSAIDs like ibuprofen and naproxen are toxic to dogs, and acetaminophen can cause liver failure. Aspirin is sometimes used in dogs but requires specific dosing and should only be given under vet guidance.

Do dogs show pain differently based on their personality?

Yes, significantly. Stoic dogs — many working breeds, some terriers — often mask pain until it's quite severe. Sensitive dogs may react to mild discomfort very visibly. Knowing your dog's baseline behavior is important for recognizing when something is off, because deviations from that baseline are the clearest signal.

Signs Your Dog Is in Pain

Dogs hide pain. It's not stubbornness or stoicism for your sake — it's a deeply instinctive behavior. In the wild, showing weakness attracts predators and lowers status in the pack. Domestic dogs have the same instinct despite having nothing to worry about. The result is that a dog can be in significant pain and show very few of the signs most people expect.

Knowing what to actually look for is important, because "not crying" doesn't mean "not hurting."

Behavioral changes — often the earliest signal

Changes in behavior are typically the first thing you'll notice, before any obvious physical symptoms:

Reduced activity or reluctance to move. A dog that normally greets you at the door but doesn't get up, or that pauses on stairs they normally take without thought.
Appetite change. Eating less or skipping meals in a dog that normally eats eagerly.
Sleep changes. Sleeping more, or conversely, restlessness — pacing, changing positions frequently, unable to settle.
Withdrawal or increased clinginess. Some dogs in pain withdraw. Others want constant contact. Either is a departure from their normal baseline.
Irritability. A usually gentle dog snapping or growling when touched in a specific area, or when they move in a certain way. This is a significant signal — they're warning you away from something that hurts.

Physical signs

Limping or favoring a limb. The most visible sign, and one of the clearest. But dogs sometimes limp on off-weight-bearing injuries and don't limp on others, so limping absent doesn't mean pain absent.
Hunched posture or a "prayer position" (front legs down, hind end elevated). This often indicates abdominal pain.
Excessive licking of a specific spot. Dogs lick painful areas. If your dog is obsessively licking a paw, leg, or their abdomen, check what's under there.
Rapid, shallow breathing or panting at rest (not after exercise, not in heat). Pain and distress trigger this in dogs.
Squinting or keeping one eye closed. Eye pain is often missed. If your dog is squinting one eye, rubbing their face, or there's visible discharge, see a vet.
Head pressing. Pressing their head against a wall or surface is a neurological sign and needs urgent veterinary attention.

What not to do

Do not give your dog human pain medication. Ibuprofen and naproxen are toxic to dogs. Acetaminophen causes liver failure. Even aspirin — sometimes used in dogs — requires specific dosing and vet guidance. VCA Animal Hospitals explicitly warns against administering any human NSAID to dogs without veterinary direction.

If your dog is showing multiple pain signs or a single serious one (head pressing, inability to stand, labored breathing), call your vet or an emergency animal clinic. "Wait and see" is appropriate for a mild limp after a walk. It is not appropriate for a dog that can't get up or seems acutely distressed.

You know your dog's normal. Changes from that baseline — however subtle — are the most reliable indicators that something is off.
