Is my dog in pain, and why do dogs hide it?

Dogs rarely show pain the way people do. Hiding weakness is an ancient survival instinct, so a dog in pain may still wag, play, and finish a walk. This plain-language guide from Tether answers the questions dog owners most often ask about pain: Why do dogs hide pain? It covers the survival instinct behind it and the difference between nociception and pain. How do I know if my dog is in pain? It lists the quiet signs to watch for, including morning stiffness, slow rising, skipped stairs or car jumps, panting at rest, guarding when touched, and changes in sleep and behavior. What is normal for my dog? It explains why a dog’s own baseline matters more than breed averages, and how pain shows up as a slow drift away from it. What do specific signs mean? It explains morning stiffness, a splayed sit, a head bob while trotting, and panting at rest, with tips for filming them at home before a vet visit. When should I see the vet? It gives a simple three-tier guide: wait and watch, call your vet tomorrow, or go now. Can a device tell if my dog is in pain? It gives an overview of The Ruff, Tether’s collar-mounted monitor. The Ruff compares movement, heart and breathing rate, temperature, vocalizations, and micro-tremors against each dog’s individualized baseline. This guide is educational. It does not diagnose pain, recommend medication, or replace a veterinary examination.
