How it works

Trailer Watchdog works by monitoring ALL critical points on your trailer, regardless of trailer type.

  • Smart Axle Monitoring + TPMS integration

    Trailer Watchdog's intelligent monitoring system tracks axles temperatures and tire data to preemptively notify you of any potential issues, preventing untimely events.

  • Suits all trailers

    Whether a camper, car hauler, boat, or horse trailer or whether you've got two, four, six or even eight wheels, Trailer Watchdog has you covered. Size doesn’t matter. Our technology works on all trailer types.

  • Use in ANY condition!

    Made in the USA with parts sourced internationally, all components of Trailer Watchdog are IP67 capable. So you don't need to worry when fully submerging your boat trailer at the ramp - Trailer Watchdog is keeping guard.

Active tire and axle temperature monitoring

TPMS is just one part of our comprehensive solution. Our innovative sensor design is compatible with all axle types, capturing axle temperatures at the base. The accompanying app then analyzes axle temperatures, air pressure, and tire temperatures across all wheels/axles, proactively alerting you to potential issues before they escalate. This means you can embark on long journeys with one less concern on your mind.

The TrailerWatchdog notified me of a wheel bearing that was getting hot while on a trip to the keys with my family. I've now bought one for each trailer I have!
