What is a Dog Tracker?

A dog tracker is a collar, or device that attaches to a collar, which enables GPS, Bluetooth, or radio frequency tracking of your pet. Many of these devices work within cellular service plans, or run off of independent network systems that piggyback off of other existing services.

How to Best Use a Dog Tracker

If you have a dog that tends to run away a lot, gets lost easily, or is new to your neighborhood, a dog tracker is the ideal tool to help you locate and keep your dog safe. Dog trackers are often used for hunting dogs, as well, helping their owners find Buttercup after she’s gone after her target.

This is one of the more well-known Garmin dog collars. It’s been reviewed over and over again by sites, with great results overall.

The Garmin GTU 10 uses the AT&T network for tracking your dog. This device attaches to your dog’s collar, in a nylon case, via Velcro, and is comfortable for your dog to wear. The Garmin GTU 10 is about the size of Snickers fun size bar, though, so is only appropriate for medium and large dogs.

The GTU 10 offers up to 10 geofences that you can configure for safety zones for your dog. You access the information via web browser or mobile app, and receive email notifications whenever your dog crosses any of his boundaries set with the geofences. The Garmin GTU 10 has unlimited tracking distance range.

You may adjust the battery settings to preserve the battery on days you know that your dog is at higher risk for running off or getting lost, such as when you’re going to a new park to run. The battery setting will determine how long the power will last.

The Garmin GTU 10 is one of the most affordable models from Garmin to date.
