How to Tell if Your Dog Is in Pain

Recognizing signs of pain in dogs can be hard, but it’s important for every loving pet owner. Dogs are experts at hiding discomfort—they can’t just tell us where it hurts, so we learn their language of pain by watching body signals and behavior. As Cornell’s canine health experts explain, “dogs cannot verbally communicate their pain; understanding their nonverbal cues is critical”. In practice, this means tuning in to subtle signals—essentially answering how to tell if your dog is hurting—so your pet gets the help it needs. For example, being aware of common dog pain body language cues (such as changes in posture or facial expression) can help you spot trouble early.

Body Language Cues

Pain often shows up in a dog’s posture and movement. You might see an arched back or a dog carrying its head low, as if something aches. Limping, stiffness, or favoring one leg are classic dog pain symptoms of injury or arthritis. Dogs in pain sometimes hesitate to jump or climb stairs, and they may get stuck after lying down. Even tail carriage can shift (a tucked tail often signals fear or pain).

A dog’s eyes and ears give clues too. Pets in pain may have flattened ears, squinted eyes or a glazed expression — some call this a “grimace.” Dilated pupils or an intense stare can also mean discomfort. If your dog looks tense or seems “distracted” by something you can’t see, it’s worth checking them over.

Behavioral Signals

Changes in your dog’s personality or routine often hint that something is wrong. A normally friendly dog might suddenly snap or growl when touched, especially if you pet a sore spot. You might notice your dog hiding in a quiet corner or refusing to cuddle like before. In fact, one emergency veterinary group notes that hiding is possibly “the most common sign of pain in dogs.” (If your pet suddenly clings, it could also be seeking extra comfort.)

Listen for vocal signs. Dogs that rarely whine may start whining, yelping or howling with pain. These sounds are essentially a cry for help. Restlessness is another clue—pacing or shifting positions, as the dog tries to find a comfortable spot. Alternatively, some pets grow lethargic, lying around a lot, sleeping more, or losing interest in walks they once loved.

• Key pain behaviors to watch for: New vocalizations (whining, howling), aggression or defensiveness, hiding or clinginess, pacing or restlessness, and excessive licking/chewing of one spot. Seeing several of these together is a strong warning.

Other Signs to Watch

Pain can also affect daily habits. Many dogs lose their appetite when they’re hurting. They might drink less or be picky at mealtimes. Older pets may have more accidents in the house. Excessive panting at rest, trembling, or a hunched body posture throughout the day are also red flags.

Check for subtle physical clues, too. Warm, swollen joints or wounds obviously hurt, but internal pain can be harder to spot. For example, an increase in breathing rate at rest can signal pain. If your dog suddenly stops grooming or develops mats on their fur, they might be avoiding movement due to pain.

What To Do If You Suspect Pain

If you notice any worrisome signs, trust your instincts and see the vet. It helps to document what you see: take photos or videos of your dog’s odd behaviors to share with the vet. Describe exactly when symptoms started and any changes in eating, mobility, or mood. This information can be crucial, since some dogs may hide pain at the clinic.

Don’t give your dog human pain medication or guess at treatments—these can be dangerous. Instead, keep your pet comfortable (soft bedding, gentle walks) and ask your vet about safe pain relievers. Your vet may do an exam, X-rays or blood tests to find the cause (arthritis, injury, dental issues, etc.). Once treatment begins, continue monitoring your dog’s comfort and follow the vet’s plan.

Remember: early relief makes a big difference. Hormones from untreated pain can actually delay healing. By catching pain early and working with your vet, you give your dog the best chance to stay happy and healthy.

Frequently Asked Questions

Q: How can I tell if my dog’s slowing down is due to pain or just aging?
Aging can slow dogs a bit, but pain usually comes with other clues. Watch for limping, stiffness, or changes in attitude (like suddenly being irritable or guarding). VCA veterinarians note that arthritis pain often shows as “decreased stamina on walks”, which owners might mistake for old age. If pain is treated and your dog’s energy bounces back, that’s a clear sign it was hurting, not just getting older.

Q: My dog hides when she hurts. What should I do?
It’s common for dogs to withdraw when they’re in pain. Pay attention to small clues, like fussiness or not eating. Keep a log of any unusual behaviors, even if they happen when you’re not around. Create a quiet comfortable space, but also tell your vet exactly what you’ve observed. Vets can gently examine hidden pain spots you might miss at home.

Q: When is dog pain an emergency?
Sudden, severe pain—like collapsing, extreme vocal distress, or trouble breathing—needs an emergency vet visit. Chronic or mild pain (like a nagging limp) can usually wait for a regular vet. When in doubt, call your vet or an emergency clinic. Early pain management usually helps pets recover faster and more comfortably.
