10 Signs Your Dog Is in Pain (That Are Easy to Miss)

Why Dogs Hide Their Pain

Before we dive into the dog pain indicators you should watch for, it helps to understand why your pup won't just come out and show you they're hurting. In the wild, showing vulnerability makes an animal a target for predators. That instinct runs deep — even in your pampered Labrador who's never spent a day outside a loving home.

This means that by the time a dog is limping, whimpering, or refusing food, the pain may have been building for days, weeks, or even longer. Research from the University of Lincoln suggests that owners only correctly identify pain in their dogs about 50% of the time. The other half goes unnoticed — which is why learning how to tell if your dog is in pain is one of the most important skills a pet parent can develop.

1. Subtle Changes in Posture

One of the earliest and most overlooked signs of pain in dogs is a shift in how they hold their body. A dog with abdominal pain may stand with a hunched back or a "prayer position" — front legs stretched forward, rear end raised. A dog with neck pain might hold their head lower than usual or seem stiff when turning.

These changes can be incredibly subtle. You might just think your dog looks "a little off" one day. Trust that instinct. If your dog's posture seems different for more than a day or two, it's worth a vet visit.

2. Excessive Licking or Grooming One Spot

Sure, dogs groom themselves. But when your pup keeps licking, chewing, or nibbling at one particular area — even when there's no visible wound or irritation — it can be a sign of underlying pain. Dogs often lick the area closest to where they hurt, even if the pain is internal. For example, dogs with joint pain in a leg may obsessively lick the paw or knee on that limb.

Over time, this can lead to "lick granulomas" — red, irritated patches of skin that owners mistake for a skin problem when the root cause is actually pain. If you notice your dog fixating on one spot, look deeper.

3. Changes in Sleeping Patterns

Is your dog sleeping more than usual? Or maybe they're sleeping less, seeming restless at night, circling before lying down multiple times, or getting up and repositioning constantly? Both extremes can be dog pain indicators.

A dog in chronic pain may sleep more because their body is working hard to heal, or because movement is uncomfortable. On the other hand, acute pain can make it impossible to find a comfortable position. If your dog's sleep habits shift noticeably — especially if they stop sleeping in their favorite spot — pay attention.

4. Reluctance to Jump, Climb Stairs, or Play

This one is easy to chalk up to "getting older." And yes, aging naturally slows dogs down. But a sudden or significant drop in activity — especially reluctance to do things they used to love — is one of the clearest signs of pain in dogs. If your couch-jumping Beagle suddenly waits to be lifted, or your fetch-obsessed Border Collie walks away from the ball, something is likely wrong.

• Hesitation before jumping onto furniture or into the car
• Taking stairs one at a time, or avoiding them entirely
• Lagging behind on walks that used to excite them
• Stopping mid-play and lying down
• Avoiding roughhousing with other pets or family members

5. Panting When They Shouldn't Be

Dogs pant to cool down — that's completely normal. But panting at rest, in a cool room, or in the middle of the night? That's a red flag. Unexplained panting is one of the most common (and most missed) ways to tell if a dog is in pain. It's their body's stress response, and it often accompanies conditions like arthritis, internal pain, or post-surgical discomfort.

If your dog is panting heavily and there's no obvious heat- or exercise-related reason, especially if it's paired with restlessness or other signs on this list, schedule a vet appointment.

6. Avoiding Touch or Flinching

Does your normally cuddly dog pull away when you pet a certain area? Do they flinch, snap, or give you a warning look when you touch their back, hips, or belly? This is your dog telling you — as clearly as they can — that something hurts there.

Even dogs who have never shown an ounce of aggression may growl or snap when a painful spot is touched. This isn't bad behavior; it's a pain response. Never punish a dog for reacting to pain. Instead, take note of exactly where the sensitivity is and share that with your vet.

7. Changes in Appetite or Drinking Habits

A dog who suddenly loses interest in food — especially a dog who normally lives for mealtime — may be in pain. Dental pain, abdominal pain, and nausea can all suppress appetite. Some dogs will also drink more or less water than usual when they're uncomfortable.

Watch for these appetite-related signs of pain in dogs:

• Picking up food and dropping it (often a sign of dental or mouth pain)
• Eating more slowly than usual
• Turning away from treats they normally devour
• Drooling more than usual during or after meals
• Drinking excessively or hardly at all

If your dog skips more than one meal or you notice a clear pattern of decreased interest in food, don't wait. Loss of appetite paired with lethargy is especially concerning.

8. Whimpering, Whining, or Unusual Vocalizations

This one seems obvious, but it's surprisingly easy to misinterpret. Dogs don't always cry out in a dramatic, movie-worthy way. Pain-related vocalizations are often quiet — a soft whimper when getting up, a groan when lying down, or a yelp when touched in a specific spot. Some dogs vocalize more at night when the house is quiet and there are fewer distractions from their discomfort.

On the flip side, some dogs in significant pain go completely silent. They withdraw rather than vocalize. So while whimpering is a clear dog pain indicator, the absence of sound doesn't mean absence of pain.

9. Personality or Behavioral Changes

This is the sign that pet parents describe as "they just aren't themselves." A normally social dog becomes withdrawn. A usually calm dog becomes clingy or anxious. A gentle dog becomes snappy with the kids. These behavioral shifts are among the most telling — and most heartbreaking — signs of pain in dogs.

Pain affects mood, and dogs are no exception. If your dog is acting differently and you can't pinpoint a reason (no changes in routine, no new stressors, no recent moves or family changes), pain should be on your list of possibilities.

10. Changes in Facial Expression

Believe it or not, dogs have a "pain face" — and researchers have actually developed tools to measure it. The Glasgow Composite Pain Scale is used by veterinarians, but you can spot some of the same clues at home:

You know your dog's face better than anyone. If something looks different — a tightness that wasn't there, a distant look in their eyes — trust your gut. You're probably picking up on something real.

What to Do If You Suspect Your Dog Is in Pain

If you've read through this list and recognized one or more of these signs in your dog, here's what to do next:

1. Don't give human pain medication. Ibuprofen, acetaminophen, and aspirin can be toxic — even fatal — to dogs. Always consult your vet first.
2. Document what you're seeing. Write down the specific behaviors, when they started, and how frequently they occur. Video can be incredibly helpful.
3. Call your veterinarian. Describe the signs you've noticed. They'll help you determine whether it's an emergency or something that can be evaluated at a regular appointment.
4. Keep your dog comfortable. Provide a soft, supportive resting area. Limit strenuous activity. Keep the environment calm and quiet.
5. Follow through on diagnostics. Your vet may recommend X-rays, bloodwork, or other tests. These aren't upsells — they're how hidden pain gets identified and treated.

Common Conditions That Cause Hidden Pain in Dogs

Understanding what might be causing your dog's discomfort can help you connect the dots between behavior changes and potential health issues. Here are some of the most common culprits behind chronic or hidden pain:

Many of these conditions are highly treatable — especially when caught early. Modern veterinary medicine offers everything from anti-inflammatory medications and physical therapy to laser treatments and even acupuncture for dogs. The sooner you identify the signs of pain in dogs, the sooner your pup can feel like themselves again.

Celebrate Your Dog While They're Feeling Great

Being attentive to your dog's health is one of the most loving things you can do. And while we're on the topic of love — there's nothing like celebrating your pup in a way that lasts forever.

It's a beautiful way to honor the bond you share, and kids especially adore seeing the family pet in their very own illustrated adventure. You can preview a book for free — no credit card needed.

The Bottom Line: You Know Your Dog Best

No article, checklist, or Google search replaces the knowledge you have about your own dog. You know their quirks, their habits, their favorite sleeping positions, and the exact way they greet you at the door. When something feels different — even if you can't quite put it into words — take it seriously. Dogs are stoic, but they're counting on us to notice what they can't say.

Knowing how to tell if your dog is in pain isn't about being paranoid. It's about being prepared. And with the information in this guide, you're now equipped to catch the subtle signs that so many owners miss — and to get your best friend the care they deserve.
