Want to take your dog hiking with you off-leash? Or do you have a Houdini hound at your home? A Global Positioning System (GPS) dog collar or tracking device could be just what you need. These tools allow you to keep track of your dog’s location and where she’s heading via tracking technology located in a device on their collar. Learn more in our best GPS dog collar review.

Article Overview

Benefits Of GPS Collars

The American Society for the Prevention of Cruelty to Animals (ASPCA) found in a study that 14% of lost dogs are never located. The best way to find a lost dog is to scour your neighborhood and make sure your dog has an accurate ID tag on her collar.

On the other hand, imagine if you could know the instant your dog roams away and track where she’s heading. The peace of mind is worth it. Also, if you take your dog hiking off-leash, she’s free to explore far away from you without you having to worry about where she is.

GPS Microchip vs Standard Microchip: What’s The Difference?

When you hear the word microchip associated with pets, you typically think of microchips embedded subcutaneously. But there are some significant differences between an internal microchip and a GPS microchip for dogs and how they allow you to keep track of your dog.

GPS Microchip

A GPS chip for dogs is external, usually worn on your dog’s collar. The GPS chip sends a continuous signal to the global satellite system, which allows you to see your dog’s exact location in real-time. Some GPS pet trackers can also feature message alerts and information about your dog’s activity levels and health.

A standard microchip for dogs is implanted under your dog’s skin and contains information like the chip ID, breed, owner details, and more. You can’t track your dog’s whereabouts at any given time with a standard microchip. It’s only helpful if someone finds your dog and takes them to a shelter or a vet’s office with a particular scanner to read the chip.

Best GPS Collar Overall: Garmin Dog Tracker Astro 430 T5 Review

Garmin Astro 430/T5View on Amazon

Although mainly marketed for sporting dogs, the Garmin Astro 430 makes an excellent GPS tracker for avid hikers, campers, and those living on large, remote farms.

One of Garmin dog tracker’s most prominent selling points? It’s a self-contained GPS unit (that doesn’t rely on cellular service) and has GLONASS reception that performs better in challenging environments.

The waterproof GPS collar transmitter has a sturdy, adjustable steel antenna, which transmits your dog’s position as often as every five seconds to your handheld receiver. The signal is strong enough to track your dog’s status even in heavy tree cover or deep canyons.

The receiver has a 2.6-inch color display, which lets you see your dog’s current location and a trail of her previous path on the map. The Garmin Astro 320 is feature-rich with an electronic compass, enhanced map drawing capabilities, BirdsEye Satellite Imagery compatibility, and much more.

Findster Duo+ with appBest Value: Findster Duo+

View on Chewy

Don’t want to pay a fortune upfront or a monthly fee for a GPS collar? The Findster GPS collar could be your best bet. Findster’s MAZE technology uses two modules, one for your dog’s collar and one for you. The technology allows these devices to communicate with each other, eliminating the need for a cellular connection.

This GPS collar also doubles as an activity monitor by tracking your pet’s fitness and activity levels. The downside? Its range is limited to 1/2 mile in urban areas and 3 miles in remote locations, so it’s not ideal for sporting or hiking.



  • It doesn’t require cell service or monthly service fees
  • Works anywhere in the world
  • Waterproof up to 3 feet
  • Lightweight and compact
  • Receive alerts if your dog leaves her safe zone
  • Uses rechargeable lithium-ion batteries
  • The range is limited to 1/2 mile in urban areas
  • It can only track 3 pets
  • Several user complaints that it loses the signal frequently
  • Customers say it’s bigger than it looks, so it’s not suitable for tiny dogs or cats

Pricing & Tech Specs

  • $184.99 for 1 pet tracker
  • 2-year limited warranty
  • 2 rechargeable lithium-ion batteries included
  • 0.8 oz device weight

Best For Escape Artists: Tractive GPS Pet Tracker Review

View on Amazon

Tractive GPS Pet Tracker is an excellent option if you live in the city or suburbs and have a dog who likes to stray. The Tractive device attaches securely to most collar types and includes a built-in SIM card, which allows you to track your dog from your smartphone or PC.

Its live-tracking mode lets you see where your dog has traveled and where she’s heading. You can also set up a safe zone via the app and receive a text alert if your dog leaves the area.

The downsides? You must be in the range of a cell tower for this GPS dog tracker to work — and pay a monthly service fee. Tractive isn’t the best dog GPS tracker on the market, but if you’re on a limited budget and don’t need GPS in very remote areas, you should give it some consideration.



  • Affordable pricing
  • Easy to set up and activate
  • Lightweight device for dogs 9 pounds or more
  • Receive text alerts if your dog leaves her safe zone
  • Compatible with iOS, Android, and Windows smartphones
  • Batteries last 2 to 5 days, and it fully recharges in 2 hours
  • GPS device relies on cell service, so it doesn’t work out of a cell tower range
  • You must pay a monthly service fee ($5-$7)
  • Some consumer complaints about short battery life

Pricing & Tech Specs

  • $49.99
  • The monthly service fee starts at $5 per month

  • 1-year limited warranty
  • 1.2 oz. device weight

Best For Small Dogs: Trackimo Review

TrackimoVisit Website

Trackimo is similar to the Tractive GPS Pet Tracker in that it relies on cell service and requires a monthly service fee. But Trackimo is more compact than Tractive, making it an excellent option for smaller dogs.

You’ll end up paying more upfront for Trackimo, but it offers a free year of service, and then you’ll end up paying $5 per month. Since Trackimo relies on cell service, it’s not ideal for remote areas. But if you live in an area with reliable cell service, Trackimo is another excellent option for pets who tend to roam.



  • Reasonably priced
  • Easy setup and activation
  • Lightweight and extremely compact device
  • Battery life up to 96 hours
  • Receive text or email alerts if your dog leaves her safe zone
