Know how your dog feels. Even when you're not home.

Tailways is a harness that reads your dog's emotional state in real time and starts a gentle calming rhythm the moment anxiety takes hold. Automatically, or from your phone, from anywhere.

We're building 10 units for 10 dogs. Applications are read by hand.

Every dog has a way through the day. This is one of them.

Tailways is an experimental wellness device. Not a veterinary or medical product. It does not diagnose, treat, or cure any condition. Consult your veterinarian.

The problem

You already know the sound.

The pacing that starts around two in the afternoon. The whining behind the door. The panting that begins before you've even heard the first thunderclap. You've tried the calming chews, the longer walk, the TV left on. And you still spend the afternoon wondering how bad it got while you were gone.

How it works

Sense. Understand. Calm. Learn.

A closed loop that runs on the harness itself. No internet required.

You're in a meeting. Your phone says Luna is anxious.

You tap once. Two hundred miles away, a slow heartbeat rhythm starts against your dog's shoulders. You watch the score come down on your screen. It's not the same as being there. It's the closest thing we could build.

This is the real thing, not a render.

Every photo below is the working prototype on a real dog. The charts are real recorded sessions, not illustrations. We're early, and we'd rather show you exactly how early than sell you a picture of something that doesn't exist yet.

Four weeks. Your dog. Our hardware.

We're hand-building ten units. If your dog is a fit, you get one, a fitting session with the person who built it, a live dashboard for your dog, and a report every Sunday showing how the week actually went. For the first ten we fit every harness in person, so we're starting close to home. If you're further away, apply anyway and tell us where you are, it helps us decide where the second group goes.

Thanks, we've got it. You'll hear from us within a week, either way.
