Research tells us that chronic pain cannot be effectively assessed in a clinic. This isn’t due to lack of skill or care on the part of veterinarians, but because the context itself makes it nearly impossible.
1. Pain behaviour changes depending on where the animal is and how they feel about that place. A vet clinic is unfamiliar, noisy, and filled with smells. Most dogs experience stress or fear there which can suppress outward signs of pain.
2. When dogs are stressed, adrenaline and cortisol rise. These hormones dampen pain perception, allowing the dog to appear “normal” even when they are not. It’s very common for a dog who limps at home to walk almost soundly in the clinic.
3. A vet consultation usually lasts 20 minutes. Chronic pain, however, is a condition of patterns, subtle changes in posture, behaviour, mobility, sleep, and mood over time.
4. Dogs are often held for examination. Even gentle handling can cause them to freeze or shut down. A dog that is tense or compliant under restraint may appear cooperative but is actually suppressing communication.
5. Clinic floors are typically slippery, and rooms are small. Dogs who are cautious about movement, weight-shifting, or joint pain will move differently in this setting not because they are pain-free, but because they are trying not to slip.
6. Dogs rarely yelp in chronic pain. Yelping is an acute pain response, a reflex to sudden, unexpected pain. Chronic pain is different. It develops slowly, often affecting multiple systems. Dogs adapt by changing how they move, sleep, interact, or express emotion. They may become quieter, withdrawn, restless, irritable, or reactive. Chronic pain alters the nervous system gradually, and because it becomes the “new normal,” dogs stop signalling it in obvious ways.
8. The most accurate information about chronic pain comes from a dogs behaviour, reluctance to jump, shorter walks, altered posture, increased irritability, licking or chewing at body parts, or changes in sleep and play.
Stress, restraint and environment all interfere with true pain expression. Defensive behaviour often reflects discomfort, and the absence of yelping does not mean absence of pain.
