Peace of mind, mile after mile.

Small problems become big emergencies at highway speeds. TrailerWatchdog sees the early warning signs you can’t—heat, pressure, and trends—so you can fix issues before they ruin your day.

AXLE & BEARING RISK

Wheel-end failures start with heat.

The data shows it clearly: 21% of breakdown calls are bearings/hubs and 11% are axles. TrailerWatchdog monitors each axle’s temperature and tire data in real time, alerting you before a blowout, hub fire, or wheel-off.

COMPLIANCE & UPTIME

Keep your trailer out of the shop.

A wheel-end failure isn’t just a breakdown, it’s a crisis in motion. Bearing and axle problems can escalate from silent to catastrophic in minutes, putting your trailer, fellow drivers, and your best friend in the back at risk. The first warning isn’t a sound; it’s heat.

TrailerWatchdog gives per-axle temperature + TPMS, turning surprise events into scheduled service—before disaster strikes.

HORSE TRAILER SAFETY

Your horse’s first warning is heat.

The TWD-1400 monitors each axle’s temperature in real time, detecting dangerous heat spikes at the hub long before you’d ever see smoke or smell burning grease. That early alert means you can pull off safely, protecting your trailer from costly damage—preventing accidents that endanger others, and keeping your horse or livestock calm, safe, and on their way home.

Because on the road, every second counts, and every life matters.

  • Not just a Tire Pressure Monitoring System

    Smart Axle + TPMS Monitoring. Trailer Watchdog's intelligent monitoring system tracks both axle temperatures and tire data to preemptively notify before disaster strikes.

  • We mean ANY Trailer

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

  • Use in ANY condition

    All components of TrailerWatchdog are IP67 capable (like, super waterproof). So you don't need to worry when fully submerging your boat trailer at the ramp – Trailer Watchdog is keeping guard.

Real-time axle temperatures and tire 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!
