By Dr. Lisa Park, DVM — Geriatric Dog Care Specialist
Last year, a patient of mine — a 12-year-old golden retriever named Biscuit — came in for what his owner described as “just slowing down with age.” He was moving a little more carefully, sleeping more, and wasn’t as excited about his evening walks. His owner had accepted this as normal. After a thorough exam and X-rays, we found severe hip arthritis that was causing Biscuit significant daily pain. He’d been living with it for probably a year.
This story breaks my heart — not because his owner didn’t care (she adored him) — but because dogs are experts at hiding pain. It’s evolutionary: in the wild, showing weakness means becoming prey. So they mask it beautifully, and we miss it.
If your dog is a senior (7+ for large breeds, 9+ for small breeds), this guide is for you. Learning to read the subtle signs of pain is one of the most important things you can do for your aging companion.
Why Dogs Hide Pain So Effectively
Unlike humans, who tend to vocalize discomfort, dogs are stoic by nature — and senior dogs especially so. Years of life have reinforced that “normal” means being active and social; when pain sets in gradually, they adapt their behavior incrementally rather than dramatically. By the time you notice something is wrong, they may have been struggling for months.
This is compounded by the fact that many signs of pain mimic “normal aging.” A dog who used to jump on the bed but now doesn’t — is that arthritis, or just getting older? (Hint: dogs don’t “just get older” and lose the desire to be near you. Pain is usually the answer.)
The key is knowing what to look for.
Behavioral Signs Your Senior Dog Is in Pain
Changes in behavior are often the first clues, and they’re easy to dismiss. Watch for:
Changes in Social Behavior
- Withdrawal or hiding: A dog who used to greet you at the door now retreats to a back room. Pain makes socialization feel like too much effort.
- Clinginess or increased neediness: Some dogs do the opposite — they become Velcro dogs, seeking comfort from you constantly.
- Irritability or uncharacteristic aggression: A dog who snaps when touched in a previously fine area is telling you that spot hurts. Growling when petted, especially over the back or hips, is a pain signal, not a behavioral problem.
- Loss of interest in play: Not just reduced play, but a dog who used to brighten at the sight of a ball and now looks away. That shift in joy is significant.
Changes in Sleep and Rest
- Sleeping significantly more: Pain is exhausting. If your dog is sleeping 18+ hours a day, something is wrong.
- Restlessness or inability to settle: The flip side — a dog who can’t find a comfortable position, circles repeatedly before lying down, or gets up and moves frequently at night. This is often joint pain.
- Sleeping in unusual spots: Avoiding their normal bed (especially if it requires jumping) or moving to cooler/harder surfaces.
Changes in Appetite and Thirst
- Reduced appetite: Pain suppresses appetite, particularly oral pain from dental disease (extremely common in seniors).
- Changes in drinking habits: Increased thirst can signal kidney disease or diabetes; decreased thirst combined with appetite loss suggests feeling unwell.
- Difficulty eating or dropping food: Dental pain, jaw problems, or neck arthritis that makes lowering the head to a bowl painful.
Changes in Vocalizations
- Whimpering, whining, or yelping — especially when moving, being touched, or getting up
- Increased vocalization at night (can also be cognitive dysfunction, but often has a pain component)
- Groaning when lying down or standing up
Physical Signs Your Senior Dog Is in Pain
Alongside behavioral changes, watch your dog’s body carefully:
Movement and Gait
- Limping or favoring a leg: Can be subtle — a slight head bob when walking, or stepping more lightly on one paw.
- Stiffness after rest: Classic arthritis presentation. Your dog gets up from sleep and moves stiffly for 5–10 minutes before loosening up.
- Reluctance to climb stairs, jump, or get in the car: Not laziness — these movements require hip flexion and joint loading that hurts.
- Shortened stride: Steps seem smaller and more careful than they used to be.
- Bunny-hopping: Using both back legs together when running — a classic sign of hip pain.
Posture and Body Language
- Hunched back or lowered head: Guarding painful areas.
- Tucked tail: Beyond fear — chronic tail-tucking can indicate back or tail pain.
- Weight shifting: Constantly shifting weight from paw to paw when standing.
- Squinting or partially closed eyes: Often a sign of headache or general discomfort, or eye pain specifically.
Physical Appearance
- Licking, chewing, or biting at a specific spot: Localized pain often triggers this response. Check for wounds, swelling, or heat in that area.
- Muscle loss: Particularly over the hindquarters or one side of the body, often indicating reduced use of that area due to pain.
- Changes in coat quality: Difficulty grooming (especially reaching the back or rear) leads to mats and dull coat over painful areas.
- Swollen joints: Visible swelling at knees, hips, or elbows in severe arthritis.
Pain vs. Normal Aging: How to Tell the Difference
Here’s my clinical rule of thumb: behavioral or physical changes that are progressive, sudden, or that interfere with things your dog used to enjoy are almost never “just aging.” They warrant investigation.
Normal aging might look like: sleeping a bit more, preferring shorter walks, being calmer at home, some graying around the muzzle.
Pain looks like: refusing walks entirely, yelping when touched, visible lameness, dramatic personality changes, not eating.
When in doubt, apply what I call the “Biscuit Test”: if your dog’s quality of life has changed enough that someone who knew them 2 years ago would notice and be concerned — it’s time to act.
What to Do Immediately
If you suspect your senior dog is in pain:
- Don’t give human pain medications. Ibuprofen, acetaminophen, and aspirin are toxic to dogs. Even “dog-safe” over-the-counter NSAIDs should only be used under veterinary guidance.
- Restrict activity. No jumping, running, or stairs until you know what’s going on.
- Make note of what you’ve observed. When did symptoms start? What makes them better or worse? Is it constant or intermittent? Video your dog moving — it’s incredibly helpful for your vet.
- Call your vet. For sudden acute pain (yelping, inability to move, labored breathing, collapse) — go to an emergency clinic now. For gradual signs — get an appointment within 1–2 weeks, not months.
Veterinary Treatments for Pain in Senior Dogs
Modern veterinary medicine has excellent options for managing senior dog pain:
Medications
- NSAIDs (non-steroidal anti-inflammatory drugs): Carprofen, meloxicam, galliprant — the workhorses of canine pain management. Regular bloodwork is needed to monitor kidney and liver function in seniors.
- Gabapentin: Excellent for neuropathic pain and as an adjunct to NSAIDs. Very well-tolerated in older dogs.
- Librela (bedinvetmab): A newer monthly injection that targets nerve growth factor — a significant advance for arthritic dogs. Many of my patients have had life-changing responses.
- Tramadol: Used for moderate to severe pain, often in combination with other medications.
Physical Therapies
- Hydrotherapy (underwater treadmill): Allows exercise with reduced joint loading. I’ve seen arthritic dogs transform with consistent hydrotherapy.
- Laser therapy (photobiomodulation): Reduces inflammation and pain at the cellular level. Multiple peer-reviewed studies support its use.
- Acupuncture: I know it sounds alternative, but veterinary acupuncture has legitimate evidence behind it for chronic pain management.
- Massage and passive range of motion: Something you can learn to do at home with guidance.
At-Home Management: What You Can Do Right Now
Beyond veterinary treatments, home management makes an enormous difference:
Environment Modifications
- Add ramps or steps to furniture and the car
- Place rugs on slippery hardwood or tile floors (slipping is scary and painful for arthritic dogs)
- Raise food and water bowls (reduces neck strain)
- Gate off stairs if they’re causing problems
The Right Bed Matters More Than You Think
An orthopedic dog bed with memory foam or solid orthopedic foam (not just fluffy stuffing that compresses) can dramatically reduce morning stiffness. Look for beds with low entry points so your dog doesn’t have to step up, with washable covers (seniors sometimes have accidents), and with sufficient support to keep joints neutral. This is one of the best investments you can make for a painful senior dog.
Joint Supplements
Glucosamine and chondroitin can support joint health over time. A product I frequently recommend is Nutramax Cosequin DS — it’s one of the most well-researched canine joint supplements on the market, with multiple clinical studies supporting its use. Start it early; it works better for prevention and mild cases than for severe end-stage arthritis.
Exercise: The Right Kind
Counterintuitively, gentle consistent exercise is medicine for arthritic dogs. The goal is low-impact movement that maintains muscle mass and joint fluid circulation. Short, flat leash walks twice daily are better than one long hike. Swimming is ideal if accessible. Avoid weekend-warrior patterns (sedentary Monday–Friday, big hike Saturday) — that’s how you cause flares.
Weight Management
Every extra pound is roughly 4 pounds of pressure on your dog’s joints. This is the single most impactful thing many senior dog owners can do. If your senior is even slightly overweight, work with your vet on a caloric plan.
Conclusion: Be Your Dog’s Advocate
Dogs can’t tell us they’re hurting. That responsibility falls to us — to pay attention, to notice the small shifts, and to act on what we see. The good news is that pain in senior dogs is almost always manageable once we identify it. Biscuit, my golden retriever patient? He’s been on meloxicam and gabapentin for eight months now. He bounced back to greeting his owner at the door, asking for walks, and sleeping soundly through the night.
Don’t accept pain as the price of age. It doesn’t have to be.
