Top 7 Warning Signs Your Dog Might Be in Pain—Even If They’re Hiding It

Subtle behaviors to watch for and when to consult your vet

Dogs are masters of hiding pain. It’s in their nature—instinctively, showing weakness can make them vulnerable in the wild. But as loving pet parents, it’s our job to pick up on those subtle signs that something’s not right. Whether it’s a minor injury or a serious condition, early detection can make all the difference in your dog’s comfort and health.

Here are the top 7 warning signs your dog might be in pain—even if they’re trying to act like everything’s fine.

1. Change in Behavior or Personality

If your usually energetic pup is suddenly withdrawn, moody, or overly clingy, pain could be the reason. Some dogs become unusually quiet, while others may growl or snap when touched—especially in painful areas.

What to look for:

• Unusual aggression or irritability

• Hiding or avoiding interaction

• Needing more attention than usual

  
  

2. Loss of Appetite

Dogs rarely skip meals unless something is wrong. A sudden disinterest in food (or water) can be a red flag for pain, especially dental pain, digestive issues, or internal discomfort.

When to worry: If your dog refuses food or treats for more than 24 hours, consult your vet.

3. Limping or Difficulty Moving

This one may seem obvious, but subtle changes like stiffness after resting or reluctance to jump on the couch may signal joint pain, arthritis, or an injury.

Also watch for:

• Slower walks

• Difficulty getting up

• Avoiding stairs or furniture

  
  

4. Excessive Grooming or Licking

Dogs often lick or chew at a painful area—sometimes to the point of causing hair loss or irritation. It might not always be where the problem is; for example, leg licking can stem from hip or back pain.

Hot tip: If your dog is obsessively licking one spot, it might be time for a vet check.

5. Changes in Breathing or Panting

Fast, shallow breathing or panting without exertion can indicate pain or discomfort. If your dog seems restless and can’t settle down, pay attention.

Additional signs:

• Pacing or whining

• Trembling or shaking

• Restlessness at night

  
  

6. Vocalization You Haven’t Heard Before

Whining, yelping, groaning, or even sighing can be a cry for help. Some dogs become more vocal when in pain, while others go silent. Know your dog’s “normal” and trust your gut when something feels off.

7. House Soiling or Bathroom Changes

If your dog is suddenly having accidents indoors or straining to go potty, it could be due to pain. Urinary tract infections, arthritis (which makes squatting painful), or gastrointestinal distress are common culprits.

Pain Can Be Silent—So Observation Is Key

Dogs can't tell us what hurts, but their bodies do. The more time you spend with your pup, the more attuned you’ll be to those subtle changes. Always trust your instincts—if something feels wrong, it probably is.

When to Contact Your Vet

If your dog shows one or more of these signs for more than a day or two—or suddenly becomes very uncomfortable—contact your vet immediately. Don’t wait it out. Pain can worsen quickly or signal a more serious condition.

In emergencies, such as:

• Crying out in pain

• Unable to stand or walk

• Swollen abdomen

• Seizures or collapse→ Head to an emergency vet ASAP.
