10 Signs Your Dog Is in Pain (Dogs Hide It Well)

Why Dogs Hide Pain

In the wild, showing vulnerability invites predation. Dogs have retained this survival instinct even though they have been domesticated for thousands of years. A dog can have a fractured toe, a raging ear infection, or severe arthritis and show only subtle behavioral changes that are easy to dismiss.

This is why so many owners are shocked when a veterinarian discovers a significant problem. “But she seemed fine” is one of the most common things vets hear. The dog was not fine. She was just doing what millions of years of evolution taught her to do: hide it.

Understanding these subtle cues is one of the most valuable skills you can develop as a dog owner. The earlier you recognize pain, the sooner treatment can begin, and the better the outcome. If you keep a dog first aid kit at home, you will already be prepared to handle many of the situations that arise once you identify a problem.

The 10 Signs

1. Changes in Eating Habits

A sudden decrease in appetite, dropping food while chewing (dental pain), or refusing hard treats while still accepting soft food. Some dogs with mouth pain will approach their food bowl eagerly, start to eat, then pull away. Others will chew only on one side of their mouth.

Pay attention to the specifics of the change. A dog that has always eaten enthusiastically and suddenly becomes a picky eater is telling you something.

2. Panting When at Rest

Panting outside of exercise or heat is a common pain indicator, especially abdominal or orthopedic pain. If your dog is lying down in an air-conditioned room and panting, that is not normal temperature regulation. It is often a stress or pain response.

Panting accompanied by restlessness, pacing, or an inability to settle is particularly concerning and often indicates moderate to severe discomfort.

3. Reluctance to Jump or Climb Stairs

A dog that used to leap onto the bed but now hesitates or refuses likely has joint or back pain. This sign develops gradually, and many owners attribute it to the dog “just getting older” rather than recognizing it as a treatable pain issue.

Watch for hesitation at the bottom of stairs, circling before lying down (trying to find a comfortable position), or reluctance to get in and out of the car. These are all red flags for orthopedic pain.

4. Limping or Favoring a Leg

Obvious, but many owners dismiss mild, intermittent limping as “they just slept funny.” If it persists for more than 24 hours, see a vet. Intermittent limping that appears after exercise but resolves with rest is a classic early sign of joint disease or a soft tissue injury that will worsen without intervention.

Even subtle gait changes matter. A dog that is slightly shorter in stride on one leg, or that carries their head differently while walking, is compensating for pain.

5. Excessive Grooming of One Area

Repetitive licking or chewing at a specific body part often indicates localized pain beneath the skin. Dogs frequently lick at arthritic joints, creating “lick granulomas” (thickened, discolored patches of skin). They may also excessively lick paws, which can indicate anything from allergies to referred pain from a shoulder or elbow issue.

If the licking is constant and focused on one spot, look deeper. The problem is rarely the skin itself.

6. Changes in Posture

A hunched back, tucked abdomen, or a “prayer position” (front end down, rear up) can indicate abdominal pain. The prayer position is particularly associated with pancreatitis, a painful inflammation of the pancreas.

Dogs with back pain often walk stiffly, with a roached (arched upward) spine. Dogs with neck pain may hold their head low and resist looking up or turning their head to one side.

7. Increased Aggression or Irritability

A normally gentle dog that snaps when touched in a certain area is telling you that area hurts. This is not a behavior problem. It is a pain response. Dogs that growl when you reach toward their hips, flinch when you touch their ears, or snap when picked up are communicating the only way they know how.

Never punish a dog for pain-related aggression. Address the underlying pain, and the behavior resolves.

8. Withdrawal

Seeking isolation, hiding, or avoiding interaction when they are normally social. A dog that stops greeting you at the door, retreats to a quiet room, or no longer wants to be part of family activities may be in significant discomfort.

This is often one of the earliest and most overlooked signs. Owners may interpret it as the dog maturing, becoming calmer, or simply aging. But a sudden or progressive withdrawal from normal social behavior deserves investigation.

9. Changes in Sleep Patterns

Restlessness, inability to get comfortable, pacing at night, or sleeping significantly more than usual. Dogs in pain often shift positions frequently, sigh heavily when lying down, or wake from sleep and reposition multiple times during the night.

If your dog was always a sound sleeper and starts waking at night or pacing, pain should be high on the list of possible causes. An orthopedic dog bed and veterinary evaluation should both be considered.

10. Vocalization

Whimpering, whining, or yelping, especially when moving, being picked up, or touched in a specific area. By the time a dog is vocalizing from pain, it is usually significant. This is the most obvious sign, but it is often the last one to appear because dogs are so hardwired to stay quiet.

A dog that yelps when jumping off the couch, cries when picked up under the ribcage, or whines when you touch their ear is not being dramatic. They are in real pain.

What To Do When You Suspect Pain

The most important step is to see your veterinarian. Do not try to diagnose the problem yourself, and do not give any human medications. Many over-the-counter human pain relievers are toxic to dogs. Ibuprofen can cause kidney failure and stomach ulcers. Acetaminophen can cause liver failure. Even aspirin, while occasionally used in dogs under veterinary supervision, can cause GI bleeding.

Your vet has safe, effective options for managing pain in dogs, including veterinary-specific NSAIDs like carprofen (Rimadyl) or meloxicam (Metacam), gabapentin for nerve pain, and newer biologics like bedinvetmab (Librela) for osteoarthritis pain.

Keep a log of the signs you are observing: when they started, how often they occur, whether they are getting worse, and any specific triggers you have noticed. This information is incredibly valuable for your veterinarian. A video of the behavior can be even better, since dogs often mask pain more effectively at the vet’s office due to the adrenaline of the visit.

Understanding how to read your dog’s pain signals is just one piece of keeping them healthy. Knowing what to look for in their stool is another everyday monitoring tool that helps you catch problems early.
