This is our newest Heat Guardian, a set of a base unit (with long range antenna) and mobile unit (with loop antenna). 


Keep your pets safe and snug! The wireless Snug Dog Heat Guardian Temperature Monitor helps you watch over your pets in the car or RV to make sure that they stay healthy. If the remote temperature goes beyond a set range the unit in-hand immediately shows this on-screen and it warbles a warning.


Recharge them with a standard 5V USB charger and watch the battery last for an entire weekend. The display on top shows the current temperature as well as the battery life and signal strength. There is one button to power it on and off.


The Snug Dog Heat Guardian comes complete and ready to use. There is no service plan required.
