A small device that clips to your dog's existing collar and reads six signals of pain. The Tether app shows you what it found, what is likely causing it, and what to do about it.
Step counts never told you your dog was hurting. The Ruff is built to catch pain, and the Tether app is where you see what it found and what to do about it.
Six signals, read around the clock, so pain shows up the moment it starts.
Every reading is weighed against your dog's own normal to find what is actually wrong.
The app turns it into plain language, what it means and exactly what to do next.
Every Ruff includes 3 months of the Tether app free. The app is where you see what The Ruff picks up, as a pain score, a reason, and a next step.
2 in 3 owners miss the early signs of osteoarthritis, a disease of any age. So it goes untreated and keeps advancing. Early identification will reduce pain and lameness over the course of a lifetime.
A portion of every sale goes to our rescue partners, and we put free devices on the dogs in their care.
Our missionOsteoarthritis, joint diseases, and cruciate ligament injuries are among the most common problems in dogs, and the bills only climb the longer they go undetected.
Veterinarians helped decide what The Ruff measures and how it scores it. Every claim on this site is checked against published research before it goes live, and both of our papers are open for you to read.
My own dogs wear The Ruff. So before any clinical claim reaches you, it crosses my desk, and it has to hold up to the same evidence I demand for my own canine companions.
