How PawSeniors Researches This
PawSeniors articles are written and edited in-house, then checked against primary veterinary sources before publishing.
- Every medical claim is sourced to the American Kennel Club, PetMD, VCA Animal Hospitals, or another named veterinary source, linked at the end of the article.
- Every claim is tied to a named, checkable veterinary source linked at the end of the article — nothing is published without a reference you can verify yourself.
- Articles are updated when veterinary guidance changes.
The most common signs of pain in senior dogs are quiet ones: restlessness at night, reluctance to use stairs or jump, irritability when touched in one spot, licking a single joint, and a slow loss of interest in walks or play. Because dogs instinctively hide discomfort, these small changes are often the only clues you get, and they are easy to mistake for “just getting older.”
Dogs are notoriously good at hiding pain. It is an old survival instinct, showing weakness once made an animal a target, and that instinct does not switch off just because a dog now naps on a couch instead of watching for predators. In a senior dog managing arthritis, an old injury, or an undiagnosed condition, pain rarely announces itself with a yelp or an obvious limp. It shows up first as small shifts in habit. This guide walks through what to look for, how to tell pain from normal aging, how to keep a simple record at home, and what your vet can do about it.

Why Pain in Older Dogs Is Easy to Miss
Chronic pain in a senior dog usually builds gradually rather than arriving all at once, and owners tend to adjust their expectations right alongside the dog’s declining activity. A dog that used to bound up the stairs and now walks up slowly does not look alarming in any single moment, because the change happened over months, not overnight. That gradual quality is exactly what makes it risky to wait for one clear, unmistakable sign before taking a closer look.
There is a second reason pain gets missed: chronic pain looks different from acute pain. A dog that steps on a thorn yelps and holds up its paw. A dog living with long-term joint or back pain rarely vocalizes at all. Instead it changes how it moves, rests, and interacts, and those changes become its “new normal” in the eyes of the family.
Behavioral Signs That Often Get Overlooked
A senior dog in pain may become irritable when touched in a specific spot, snapping or growling in a way that seems out of character for an otherwise easygoing dog. Restlessness at night, an inability to settle into a comfortable position, and repeated circling before lying down are common but frequently blamed on general old age rather than investigated as pain. A dog that used to greet visitors at the door and now hangs back, or one that has quietly stopped asking to play, is often communicating discomfort rather than simple disinterest.
Behavior changes worth noting include:
- Sleep changes: pacing, frequent repositioning, or getting up and lying down again and again. Pain is one of several reasons a senior dog may be restless in the evening.
- Avoiding contact: moving away when you reach for a certain area, or no longer wanting to be picked up or brushed. This can make grooming a senior dog harder.
- New grumpiness: less tolerance for other pets or children, especially when they bump into the dog.
- Withdrawal: spending more time alone, in a different room, or away from the family.
- Clinginess or anxiety: some dogs in pain do the opposite and want to stay close, follow you, or seem unsettled when left alone.
- Toileting changes: accidents in the house can happen when squatting or lifting a leg hurts, or when getting outside quickly is too uncomfortable.
- Less interest in food or toys: a dog with mouth pain may drop food or chew on one side, and a dog with back pain may not want to bend down to a bowl.
Physical Signs Beyond an Obvious Limp
Muscle loss on one side of the body often means a dog has been favoring the opposite leg for some time, quietly compensating long before an owner notices a limp. Stiffness that is worst right after resting and improves once the dog warms up is a classic arthritis pattern, while pain that gets worse the longer a dog moves points more toward an acute injury. Excessive licking or chewing at a single joint, a hunched or tucked posture, and shallow, rapid panting while at rest are all physical tells that are easy to miss if you are not looking for them specifically.
Other physical clues to watch for:
- Trouble with transitions: slow or effortful getting up, lying down in stages, or “flopping” down instead of lowering gently.
- Refusing heights: hesitating at the car, the couch, or the stairs.
- Weight shifting: standing with more weight on the front legs, or sitting to one side instead of square.
- Changes in posture: a rounded back, lowered head, or tucked tail while standing, which can point to back or belly pain. Back pain is a key sign of IVDD in senior dogs.
- Facial expression: squinting, ears held back or flat, a tense brow, or a fixed, “faraway” look.
- Trembling or shaking in the legs while standing still.
- Panting or a faster heart rate at rest, especially in a cool room. Panting mostly at night is worth mentioning to your vet.
- Worn or scuffed nails on one paw, which can mean the dog is dragging that foot.
- Thinning muscle over the hips and thighs. Some of this is age-related, but it is worth reading about muscle loss in senior dogs before assuming it is normal.
Slowing Down From Age vs. Pain
Normal aging tends to reduce a dog’s stamina fairly evenly across everything it does, a gradual, general decline in enthusiasm and endurance. Pain tends to be selective: a dog might refuse stairs specifically while still being happy to walk on flat ground, or tolerate being petted everywhere except one spot on its hip. That selectiveness, avoiding one particular movement or position while otherwise seeming engaged, is often the clearest clue that something specific hurts rather than the dog simply having less energy overall.
A useful way to think about it:
- More likely age: shorter walks at the same easy pace, more napping overall, a slightly slower start in the morning that fades quickly, with no change in mood.
- More likely pain: avoiding one activity, stiffness that lasts or is getting worse, sensitivity in one spot, changes in mood or temper, and good days and bad days that track the weather or exercise.
One more practical test: many owners only realize how much pain their dog was in after the vet starts treatment and the dog suddenly seems “younger.” Slowing down is not something a dog has to simply live with. If you are unsure what is normal for your dog’s age and size, our senior dog age chart is a helpful starting point.
Common Causes of Pain in Senior Dogs
Pain is a symptom, not a diagnosis. In older dogs, it often comes from one or more of these sources:
- Osteoarthritis in the hips, elbows, knees, or spine, the most common source of chronic pain in older dogs. Dogs with a history of hip dysplasia or certain breeds prone to joint problems are at higher risk.
- Back and neck problems, such as disc disease, which can cause a hunched posture, reluctance to turn the head, or crying out when picked up.
- Dental disease, which hurts far more than most owners expect. Read more about dental disease in senior dogs.
- Ear infections, which can cause head shaking, rubbing, and sensitivity around the head. See chronic ear infections in senior dogs.
- Belly pain from conditions such as pancreatitis, often shown as a “prayer” stance (front end down, rear end up), restlessness, or not wanting to be lifted.
- Anal gland problems, which cause scooting, licking under the tail, and discomfort when sitting. See anal gland problems in senior dogs.
- Cancer, including bone cancer, which often first appears as a limp that does not improve. Learn the warning signs of osteosarcoma and other cancer warning signs.
- Skin problems and pressure sores in dogs that lie down for long periods. See pressure sores in senior dogs.
A Simple At-Home Pain Check
You cannot diagnose pain at home, but you can collect the observations your vet needs. Try this once a week, at the same time of day, and write down what you see:
- Watch your dog get up after a nap of at least an hour. Is it smooth, slow, or a struggle?
- Watch your dog lie down. Does it lower gently, circle many times, or drop?
- Watch a short walk on flat ground. Look at the head: a head that bobs up when one front leg lands often means that leg hurts.
- Watch stairs, the car, or the couch. Does your dog hesitate, need a run-up, or refuse?
- Run your hands gently over the neck, back, hips, and legs. Note any flinching, turning to look, lip licking, or tensing.
- Compare both sides of the body for muscle size over the shoulders and thighs.
- Note mood and appetite for the week: playful, normal, quiet, or withdrawn.
- Take a short phone video of anything unusual. Many dogs act differently at the clinic, so a video is often more useful than a description.
Your vet may also use a structured pain questionnaire or validated pain scale to score how your dog is doing and track changes over time. Your weekly notes make those scores much more meaningful. For quality-of-life questions in very old dogs, the HHHHHMM quality of life scale is another useful tool.
Never Give Human Pain Medicine
It is tempting to reach for something in the medicine cabinet when your dog seems sore. Do not. Common human pain relievers such as ibuprofen, naproxen, and acetaminophen can be toxic to dogs and can cause stomach ulcers, kidney damage, or liver damage, even at doses that seem small. Older dogs, who more often have reduced kidney or liver function, are especially vulnerable. Always ask your vet before giving any medicine or supplement, and tell them about every product your dog already takes.
What to Do If You Suspect Your Dog Is in Pain
A veterinary exam is the only reliable way to identify the source of pain and rule out conditions that need more than pain management alone. It helps to bring specific observations rather than a general sense that something is off: when the behavior started, whether it is worse at a particular time of day, and which movements seem to trigger it. Waiting for pain to become obvious usually means waiting through weeks or months of a dog quietly living with something that has a real chance of being managed. Our guide to preparing for a senior pet’s vet visit has a checklist of what to bring.
Depending on the cause, your vet may suggest bloodwork before starting medication, X-rays, or other tests. Treatment for chronic pain in older dogs usually works best as a combination of approaches rather than a single fix:
- Prescription pain medication, such as veterinary NSAIDs or newer options. Learn more in our guide to prescription pain medications for senior dogs.
- Weight control, since extra weight puts more load on sore joints. See weight management for senior dogs.
- Gentle, regular exercise instead of long weekend outings. See how much exercise a senior dog needs.
- Physical rehabilitation, including hydrotherapy and guided exercises. See physical rehabilitation for senior dogs.
- Supplements your vet approves, such as omega-3 fatty acids. See joint supplements explained.
- Home changes, such as rugs on slippery floors, ramps, and a supportive bed. See home modifications for senior dogs and our orthopedic bed buying guide.
When Pain Is an Emergency
Most chronic pain can wait for a regular appointment, but some signs need same-day or emergency care:
- Sudden inability to stand or walk, or dragging the back legs
- Crying out when touched or moved, or crying out with no obvious trigger
- A swollen, hard belly, retching without bringing anything up, or restlessness after a meal (possible bloat)
- A sudden severe limp or a leg your dog will not put down
- Pain together with pale gums, collapse, or trouble breathing
- Pain after a fall, a fight, or being hit by a car
Frequently Asked Questions
Do dogs cry when they are in pain?
Sometimes, but not usually with chronic pain. Whining or yelping is more common with sudden, sharp pain. Dogs with long-term pain from arthritis or dental disease more often show it through changes in movement, sleep, and mood, which is why quiet signs matter so much.
Is panting a sign of pain in an old dog?
It can be. Panting at rest in a cool room, especially at night, is one possible sign of pain. It can also come from heat, anxiety, heart or breathing problems, or some medications, so it is worth mentioning to your vet if it is new.
Why does my senior dog lick one leg all the time?
Licking a single joint or paw is a common response to pain in that spot, though allergies, skin infections, and anxiety can also be the cause. Our article on compulsive licking in senior dogs covers the possible reasons.
Can I give my dog aspirin or ibuprofen for pain?
Not without your vet’s direct advice. Human pain relievers can cause serious harm to dogs, and they can also interact with medications your vet may want to prescribe. Safer, dog-specific options are available.
How do I know if my dog’s pain treatment is working?
Keep doing your weekly at-home check. Signs that treatment is helping include easier getting up, more willingness to walk or play, better sleep, and a brighter mood. If you see no change, or new side effects such as vomiting, diarrhea, or not eating, call your vet.
