Frequently Asked Questions

How does it work?

The Snug Dog Heat Guardian is a pair of wireless devices that read the temperature and talk to each other. They also talk Bluetooth to your phone. Inside the Heat Guardian are two radio transceivers (one long range, one Bluetooth) and two computers - one per radio.

Do I need the phone application (Heat Guardian Assistant) ?

The Assistant has two main features. It lets you update the software inside of the Heat Guardians and it lets you set the minimum and maximum temperature range for audible alerting. Neither of these are critical and your Heat Guardians will work just fine without any phone application.

How often does it check temperature?

It checks once per second to make sure your pet stays safe. The units talk to each other every 30 seconds.

Why is the temperature always shown a little high?

Inside the Heat Guardian are two computers. They warm up a little during operation and that heats the inside of the Heat Guardian one or two degrees at room temperature. As it gets hotter that effect no longer matters so when you really care about your pets the temperature is extremely accurate. At room temperature, a little less so.

How long does it take for the two units to synchronize?

If you turn them on at the same time, they will usually synchronize immediately. If not (or if they lose signal at some time) they can take up to a few minutes to find each other. Don't worry - if there is enough signal they will find each other.

​What about an emergency?

If the remote gets too cold or too hot the unit in-hand immediately plays a warble. The warble continues until you click the button.

What kind of connection do I need?

The devices are completely self-contained. Wi-Fi, Cable, Internet, Cell Service - all not required. They do have a range limitation of about 1/2 mile. The range is very dependent on metal and concrete walls and large trees. It can be as little as about 1 block to as much as miles (in an open field).

What about power?

Charge the Heat Guardian by plugging in a micro-USB power cable. Make sure the orange light next to the connector comes on. The battery lasts for about 30 hours of run time (assuming a stable remote connection). So, it will run all weekend on a single charge if you remember to turn it off at night. Charge time is about two hours.

Where should I put the units?

The boxes use radio waves so do not surround them with metal. The best place is in or near a window. Check the signal strength at first.

Is there a monthly cost?

The Snug Dog Heat Guardian must be purchased. There are no additional fees after purchase.

How do I turn it off?

Press and hold the button for about 7 seconds until the display turns off or says Shutting Down. When turned off, they still use a small amount of power so we recommend you charge before using for a weekend.

What happens when the battery really dies?

The Heat Guardian uses a Lithium-Ion rechargeable battery that has an expected life of about 2-3 years of daily use. The battery is user-replaceable.

Can I use this overseas?

Only in North and South America! The Heat Guardian uses a range of frequencies that are legal only inside ITU Region 2 (North and South America, Greenland, and some pacific islands). We may offer a version for ITU Region 1 (Europe, Africa, Middle East) in the future.
