15 Warning Signs Your Dog Could Be in Serious Pain

When your dog is in pain, they can’t say it — but they do show it. The tricky part is recognizing the signs before things get worse. Over the years, we’ve seen how subtle some of these cues can be, especially with dogs that try to tough it out. So if your pup is acting "off," here are some real signs that something might be wrong — and why it's worth calling your vet sooner rather than later.

1. Sudden Yelping or Whining When Touched

If your dog cries out when you pet or move them, it's their way of saying "ouch." Pain from a sprain, spinal issue, or even something internal can make them extra sensitive. I once had a foster pup who’d yelp just from being gently picked up — turned out he had a hidden abdominal injury. Don’t ignore this one.

2. Not Eating Like They Used To

A drop in appetite is a red flag. Pain — from dental problems to stomach issues — can make eating miserable. If your dog skips more than a meal or two, especially if they normally eat like a vacuum, get them checked.

3. Behavior That’s Just… Not Them

A normally sweet dog getting snappy or a playful pup suddenly acting withdrawn? Pain and discomfort can change behavior fast. This can also happen from meds or anxiety, but don’t write it off. It’s often your first clue something’s up.

4. Limping or Trouble Moving Around

Limping, stiffness, or hesitation to walk can point to anything from arthritis to an injury. If your dog’s gait has changed or they’re favoring a paw, it’s time for a vet visit. Waiting can make things worse, especially with joint issues.

5. Heavy Panting or Labored Breathing

Panting isn’t just about heat or excitement. If it seems excessive, happens at rest, or comes with other signs like restlessness, it could mean pain, heart problems, or respiratory trouble. Keep an eye out, especially in older dogs.

6. Restlessness and Trouble Sleeping

Struggling to get comfortable, pacing at night, or switching spots constantly can mean they’re hurting — often from arthritis, injury, or tummy issues. If your dog’s sleep habits suddenly shift, don’t ignore it.

7. Suddenly Not Interested in Walks or Play

When a dog who usually races to the leash suddenly doesn’t want to move, something’s wrong. Pain, fatigue, or illness could be making movement uncomfortable. This happened with my Ridgeback once — turned out to be early hip dysplasia.

8. Licking or Chewing One Spot Constantly

If your dog’s obsessed with licking or chewing a specific area, it might be more than a skin itch. Pain, infection, or even joint discomfort can trigger this behavior. Watch for redness, swelling, or hair loss in that area.

9. Swollen or Tender Spots

Swelling around a joint or lump that seems sensitive could signal injury, infection, or something more serious like a tumor. Any unexplained swelling should be looked at — especially if it’s growing or your dog reacts when touched.

10. Accidents in the House

A potty-trained dog suddenly peeing or pooping indoors could be dealing with a urinary or digestive issue — or even pain that makes it hard to hold it. Stress can play a role too, but if this is new and out of character, call your vet.

11. Weird Posture or Movement

Hunched back, head hanging low, or stiff walking? Dogs often adjust their posture to take pressure off painful areas. Neurological issues or joint pain can also affect how they move. Don’t wait to see if it passes.

12. Unusual Vocalizations

More barking, whining, or groaning than usual can be a cry for help. Dogs might vocalize more when they’re anxious, uncomfortable, or in pain — especially with things like bloating, seizures, or breathing issues.

13. Avoiding Stairs or Jumping

A dog who used to bound up the stairs but now hesitates could be dealing with joint pain, muscle weakness, or even a neurological issue. This is especially common in senior dogs or larger breeds.

14. Eye Changes — Redness or Cloudiness

Red, cloudy, or weepy eyes? That could mean anything from conjunctivitis to glaucoma. Eye issues can go from minor to serious fast, so if your dog’s eyes look different or they’re squinting or pawing at them, don’t delay.

15. Shivering or Trembling

Shaking can mean cold — but it can also be pain, fear, or something more serious like a fever, seizure disorder, or organ issues. If your dog’s shivering and it’s not chilly, or it comes with other symptoms, check in with your vet.

Bottom line: You know your dog best. If something seems off — even if it’s just a gut feeling — trust it. Dogs are pros at hiding pain, and catching problems early can make a huge difference. We’ve seen it time and again: a quick vet check can spare your pup a lot of suffering... and give you peace of mind.
