Pet Theory
The smart collar that helps you understand your dog, every day.
Mix it up.
Every Pet Theory collar comes with one strap. Add more colours, a spare, or a different style anytime — they click in and out in seconds.
Want location tracking too?
Pet Theory's strap has a dedicated pocket for a compatible location tracker. Add one to your order, or use a tracker you already own.

Precision Companion Tracker
Fits seamlessly into the concealed elastic pocket of any Pet Theory strap. Works alongside your existing smartphone network for global tracking with zero monthly subscription fees.
Live location appears inside the tracker provider's native network app (e.g. Apple Find My / Google Find My Device ecosystem). Pet Theory focuses on continuous biological health; pairing with your preferred network gives you the best of both worlds.
