I've watched it happen in hospitals: the dogs that wag their tails the most are sometimes suffering the most. A dog named Simba wagged constantly while breaking down inside for three weeks. Dogs hide weakness because we were never taught to show vulnerability. The lesson: stop looking at the tail. Learn to read the whole animal.
What I've noticed
The happiest-looking dogs in hospitals are often the sickest ones. I've seen it enough times to know it's not coincidence. We mistake a wagging tail for wellness because that's what we've learned to do—we look for the obvious signs of joy and assume everything underneath is fine. But animals, like people, get very good at hiding when something is wrong.
Simba's story
There was a dog named Simba whose tail never stopped wagging. His father would say, 'Look, he's completely fine'—but Simba was breaking down on the inside for three weeks. The wagging tail was his habit, his way of being. It told us nothing about what was happening in his body. By the time anyone looked deeper, he was already suffering.
Why we miss it
We hide weakness because we were never taught to show vulnerability. Dogs do the same. They learned it from us. We taught them that the performance—the tail, the energy, the outward signs—matters more than the truth underneath. So they keep performing even when they're breaking.
How to really see
Stop looking at the tail. Learn to observe the whole animal—the way they move, the energy in their eyes, the patterns that don't match the surface story. We can't talk to them and ask how they're feeling. So we have to learn to see. That's our job.
