More Wags.
Fewer Worries.
Pet Theory turns everyday moments — walks, naps and zoomies — into simple health insights, helping dog parents understand what's happening even when their dog can't tell them.
If only they could tell us.
Dogs can't tell us when something feels different. Pet Theory helps their data speak for them.
Sleeping a little longer than usual.
A bit more restless at night.
Slower to get going on today's walk.
Panting more on a warm afternoon.
Heart rate a little different than usual.

Not just dog data. Your dog's normal.
Every dog is different. Pet Theory spends the first 14 days learning what's normal for yours — resting heart rate, activity, sleep, the works — so everything after that is personal to them, not just any dog.
How a walk becomes an answer.
Four short beats from movement to insight — with zero technical jargon.
Buddy goes for his walk
An ordinary afternoon walk in the park.
Collar measures continuously
Optical PPG and precision sensors sample heart rate and gait every minute.
Pet Theory compares to Buddy's normal
Evaluated against 14 days of personal baseline data, not generic breed averages.

A calm, non-alarmist notification surfaces only if variance persists.
One app. Every good day, tracked.
From heart rate to happy naps, Pet Theory keeps a gentle eye on the things that matter — so you can just enjoy the walk.

You're all set
Pet Theory keeps watch in the background and surfaces meaningful changes from here on.
Made for dogs. Designed for everyday life.
Same health tech underneath, in colors as playful as your pup. The strap detaches, so it's easy to keep clean and easy to change — every collar comes with one strap included, and more colours are always in the shop.
Built thoughtfully. Developed with veterinary input.
Pet Theory is designed to help you notice changes worth a second look — not to diagnose. Every alert is being tested and refined with veterinary input during our pilot, built to say “worth a look,” never a scary diagnosis.
In Veterinary Clinical Pilot
Developed and refined with certified veterinary advisors during pilot trials.
Zero False-Alarm Filter
Designed to say “worth a look,” never an alarming false diagnosis.

End-to-end encrypted biometrics that belong strictly to you and your dog.
