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 a GPS microchip located in a device on her collar.

Article Overview

Benefits Of GPS Collars

The American Society for the Prevention of Cruelty to Animals found in a 2012 study that 14% of lost dogs are never found. The best way to locate a lost dog is to scour your neighborhood and make sure she 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 the exact location of your dog in real time. Some GPS pet trackers can also feature message alerts and information about your dog’s activity levels and health.

Standard Microchip

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 her to a shelter or a vet’s office that has a particular scanner to read the chip.

Best GPS Dog Collars And Trackers

There are many variations of GPS dog collars and GPS pet trackers, so we’ve broken down our reviews into categories we think will help you choose the type you need.

Best Overall GPS Collar: Garmin 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 for those who live on large, remote farms.

One of its 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.



  • No need for cell service and no monthly service fees
  • Range up to 9 miles
  • Battery life up to 20 hours with continuous use (up to 40 hours on rescue mode)
  • Receiver unit expandable up to 20 dogs (extra collars not included)
  • Collar is waterproof
  • Vibration alert if your dog leaves your designated safe zone
  • Uses rechargeable lithium-ion batteries
  • Expensive
  • Not suitable for small dogs (too large for Beagles)
  • Learning curve to set up and use

Pricing & Tech Specs

  • $649.99  for Garmin Astro 430 T5 Dog GPS Bundle (one transmitter collar and receiver)
  • 1-year limited warranty
  • Batteries not included
  • 9.2 oz. collar transmitter weight

Best Value: Findster Duo+

Findster Duo+View on Amazon

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.



  • 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
  • Range is limited to 1/2 mile in urban areas
  • 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 good for very small dogs or cats

Best For Escape Artists: Tractive GPS Pet Tracker Review

Tractive GPS Pet TrackerView 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

  • Check Amazon for availability
  • Monthly service fee starts at $5 per month
  • 1 rechargeable lithium polymer battery included
  • 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 generous 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 that has 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
  • Compatible with iOS and Android smartphones
  • Relies on cell service so it may not work in remote areas
  • You must pay a $5 monthly service fee (but the first year is free)
  • Several customer complaints that the location tracking isn’t accurate

Pricing & Tech Specs

Trackimo offers a full year of service free and a 30-day money back guarantee.

This waterproof GPS dog collar and receiver unit combines GPS tracking with Tri-Tronics training technology that uses 18 training levels of continuous and momentary stimulation.

Like the Garmin Astro, the Alpha doesn’t rely on cell service, so it’s an excellent choice for remote areas. The handheld, glove-friendly receiver features a three-inch color touch screen and comes preloaded with TOPO U.S. 100K mapping and a rechargeable battery. In addition to showing your dog’s location and direction, the Garmin Alpha even gives you each dog’s speed.

  • Battery life up to 20 hours (up to 40 hours in rescue mode)
  • Expandable up to 20 dogs (extra collars not included)

  • Expensive
  • Collar tracker is too large for small dogs

I simply attached my Trackimo tracking device to the collar of my lab. I have no complain yet since i used this tracker actually this tracker is great!

I personally like the Trackimo for my dog, it is a nice GPS tracker and it is perfect for my little buddy

I really like the 3G tracking device from Trackimo, I can set a virtual fence for my pooch and it also has the movement alert system that notifies me whenever he moves from one place to another. Great product!

I need a GPS tracker for my chihuahua. I owned a Garmin device before but he just kept on chewing it off.

You might try using 3G Trackimo device, I’m using one for my Yorkie. The device is sturdy and the monitoring features are on point.

May 14, 2018 5:29 am

Using a GPS tracker is a lot better than the Bluetooth one’s, I absolutely like the geofencing features of Trackimo giving me some peace of mind.

May 2, 2018 1:33 am

I got a Trackimo device cause I like to take my dog when I go walking/hiking and have him go on off-leash adventures too. A tracker would be a great way to keep an eye on him as he explores.

Agreeing to what you have said, it’s the tracker that maps the place out, gives fast updates on a fast moving target and accurate in locating.

How good is it?

February 10, 2018 12:41 am

We originally owned the Whistle 2. Then I got mesmerized by the design and featured of the LINK AKC. I ordered an original and it lasted only a couple of months. During that time I found the performance very poor and inaccurate. Often times the thing would not even track. Customer service replaced the unit with another sealed in box. After a short time I was so disappointed with the tracking reliability I went back to Whistle and bought a new Whistle 3. I should have never switched. The Whistle 3 is always accurate, long lasting battery and never gave my Chesapeake Bay Retriever a problem when she goes swimming. The only issue I had with it at first was the rubber band that attaches it ti the collar. Whistle re-designed that part and sent all their customers two replacements each free of charge. Fast forward months later and it works as good as new!

My dog and I go hiking quite a bit and while she’s trained to be off her leash, it makes me nervous sometimes if she were to see something and get distracted and run off. So definitely going to get a GPS tracker just in case!
