Are you looking for a smart collar for your dog? Smart collars have a variety of features, such as GPS tracking, health monitoring, and activity tracking. Some combine all these features in one collar, while others focus more on your dog’s fitness (like a Fitbit for dogs). The collar’s device connects to an app on your smartphone, where you can monitor your pup’s activity. We’ve delved into the best on the market and give you our top picks in our smart dog collar reviews.

GPS: SpotOn Virtual Fence Review

SpotOn tracker and phone

Visit Website

SpotOn GPS Fence is a superb option if you want an easy-to-use virtual fencing system and GPS tracker, particularly if you have a large property. SpotOn uses a unique “True Location” GPS technology to keep your pup contained in the boundaries you set. You can create unlimited overlapping fences that work on GPS without the monthly fee for cellular coverage.

However, SpotOn’s cell service is necessary to receive alerts that your dog has left your yard and to track his whereabouts. (You can get a 90-day free trial if you sign up for the one or two-year plan.) SpotOn has 30 customizable correction modes, including vibrations, sound, or static feedback. You also get detailed training materials and one-on-one training sessions with one of SpotOn’s certified dog trainers. The primary downsides to SpotOn GPS Fence are its high cost and that it is not designed to work in small areas.

Our Personal Experience With SpotOn GPS Fence

We had the opportunity to try SpotOn’s collar with our Cavalier King Charles Spaniel in exchange for an honest review. The collar itself was easy to set up, attach the contact points, and adjust the size. After activating the collar and creating an account, you can walk with your dog on a leash to create your virtual fence in real time. I was impressed at how detailed the fence line was and how accurate the invisible fence lines were.

When getting close to the “edge,” it makes a loud beep. As you get closer to the boundary, there is a two-tone alert. And if you cross the boundary, the collar vibrates. There’s no subscription required for the fence feedback, but if you want GPS tracking that is an additional monthly fee. If you’re looking for a way to contain your dog without a fence or wires, this training collar may beworth the investment.

All-In-One: Halo Collar 3 Review

Halo 3 Collars

Visit Website

The Halo Collar 3, backed by the famous dog expert Cesar Millan, is our top pick for the best all-in-one smart dog collar. This device is a smart wireless dog fencing system, GPS activity tracker, and remote training collar in one collar. Halo uses GPS/GNSS, LTE, Bluetooth, and WiFi technologies to set boundaries, track your dog’s activity, and send you escape alerts via the app.

You can customize Halo to keep your dog in-bounds via vibrations, sound, or static correction (a tapping sensation), effectively using it as a smart dog training collar. It includes Cesar Millan’s 21-day training program to teach your dog how to adapt to the system (and many other indoor and outdoor training tips). It also keeps track of the number of walks your dog takes and the time spent active vs resting.

The new and improved Halo Collar 3 includes upgrades that specifically address customer feedback from the original Halo Collar. These improvements include enhanced GPS coverage using cell carriers, better location accuracy, a 24-hour battery life, a much more rugged collar with a Pro-case that can withstand chewing and harsh terrain, a magnetic doc that doesn’t trap dirt and debris, as well as better cellular, WiFi, and Bluetooth performance.

The Halo could be a great solution if you need a smart training collar for a medium yard.

Our Personal Experience With Halo Collar 3

Halo Collar 3 box and contents

The app walked me through a series of training videos which are both entertaining and informative. The quality is very cinematic, and the text helps reinforce the audio instructions. After learning about types of feedback (prevention and encouragement), I worked on beacon training. This gets your dog accustomed to feedback in a safe, indoor setting.

You’ll manually give your dog feedback (sound or stimulation) and a reward to guide them away from the “no-go zone.” You’ll repeat these steps several times for 30 minutes and do at least 3-4 sessions before building up to outdoor boundaries. Eventually, when you turn the beacons on, the beacon will automatically give feedback when your pup gets within a certain range of the no-go zone. Georgie responded well to the feedback, and I am pleased with the GPS location tracking improvement from the Halo 2+ which we tested previously.

Best Value: Tractive GPS Tracker For Dogs Review

Tractive GPS Tracker For Dogs and app

View on Tractive | View on Amazon

Tractive is a very affordable smart device that snaps easily and securely on most dog collars. It uses GPS and LTE technology to keep tabs on your pup (it connects to AT&T, Verizon, and T-Mobile). And its live-tracking mode updates every two to three seconds (more often than many other devices) — an excellent feature for finding your escape artist.

You set up a virtual fence in your yard via the app and train your pup to stay within your boundaries. If your dog leaves his safe zone, the collar goes into “lost-dog mode,” and you’ll get a text alert. It also tracks your dog’s active and rest times and calories burned. And it works in over 150 countries. Tractive is an excellent value considering the accuracy and reliability of this device. This makes it one of the most affordable GPS dog trackers on the market.

Our Personal Experience With Tractive

We’ve been using Tractive for over a year with our two-and-a-half year old Cavalier King Charles Spaniel, Georgie.

He’s an escape artist so I wanted a way to be able to locate him should he get loose (in addition to having a microchip and an ID collar). I get alerts as soon as he leaves his “safe zone” on walks around the block and know when he’s safely returned.

This feature comes in handy when I’m not home; I know if my husband has taken him out on a walk. I also like seeing the heat map of where he’s been on walks when he stays with a sitter.

The Tractive device is super slim, lightweight and attaches to Georgie’s harness. He doesn’t even notice he’s wearing it but other people comment on it asking what it is!

For the price point, it’s an affordable solution to have a reliable way to keep track of your dog.

Best For Health & Fitness: FitBark 2 Dog Activity Monitor Review

View on FitBark | View on Amazon

Want to keep track of your pup’s overall wellness? FitBark 2 can turn nearly any collar into a smart collar with activity and health tracking. It fits most flat dog collars up to 1.5″ wide and is designed for dogs of all sizes. You can monitor your pup’s activity, sleep quality, distance, calories burned, and more through the mobile app. And you can set activity goals and compare your pup’s activity to dogs of a similar breed, age, and weight. You can also sync it with Fitbit, Apple Watch, Apple HealthKit, or Google Fit wearable devices.

Unlike our other top picks, this FitBark 2 device isn’t a GPS location tracker, but they do offer a separate device, the FitBark GPS Dog Tracker 2nd Gen, which combines GPS tracking with all the features of this activity monitor, all for a competitive upfront price. Just keep in mind the FitBark GPS Tracker requires a monthly subscription.

Our Experience with FitBark

Screenshot of Fitbark app

The co-founder of this website, Michelle, uses FitBark with her dog, Lily. Here’s what Michelle had to say:

We have two dogs but Lily is the one always running around the yard and getting into trouble with the wildlife. So we thought it would be interesting to see how her activity tracks throughout any given day using the FitBark. We have only had it for about a week, but Lily has exceeded her activity goals every day so far, and the well-designed smartphone app keeps us current on her activity and rest for every hour of the day. It is really neat to see how often she plays vs. is mildly active and it even surprised us to see that one night she did not sleep so well.

An added bonus, that we had not anticipated, is that when Lily’s activity was pacing below her goal for the day, the app sent a notification to let us know. That motivated us to take both dogs on a walk right away. So, the activity monitor is encouraging its owners as much as its wearer (maybe more so, ha!) to be more active.

What About Fi Collar, Invoxia & Whistle Go?

These smart collars didn’t make it into our top rankings, but they’re still certainly worth considering

Fi Smart Dog Collar Series 3 Review

Fi Smart Dog Collar Series 3

Visit Website

Fi uses GPS and the AT&T LTE-M cellular network to keep tabs on your pup in real time and has lost-dog mode escape alerts. Fi also allows you to keep track of your dog’s daily activity, from distance traveled to sleep monitoring. You can set goals for daily steps to keep your pup in shape. You can even connect with and compete with fellow Fi users. The chew-proof and waterproof collar comes in four colors and five sizes, ranging from 9.5″ to 31″, so it fits a wide variety of dogs.

To save battery life, the Fi Collar will dynamically connect to WiFi or local Bluetooth beacons, such as your phone or the Fi charging base. Many users, however, said this could be inconvenient. Users say the battery drains very quickly when not connected to WiFi or Bluetooth.

Unlike other smart dog collars, Fi includes the price of the Series 3 collar in its required subscription prices. While this may seem like an amazing deal, the subscription prices are significantly higher than others, making it more expensive over the long run.

So, why didn’t Fi make it into our top picks? We’ve seen several user reviews about the company’s poor customer service and spotty GPS location accuracy.

Invoxia Smart Dog Collar Review

Invoxia Smart Dog Collar

Visit Website

A CES 2022 Innovation Award Honoree, the Invoxia Smart Dog Collar is the first advanced biometric dog collar with GPS tracking and health scanning. What sets this collar apart from the rest? It monitors your pup’s heart and respiratory rate — a huge plus if you have an elderly or ill dog. It also includes sleep monitoring and tracks your pup’s daily steps, mealtimes, and more.

An ongoing subscription is required for the collar to transfer data via the LTE-M network. What’s not to like about this collar? The most significant missing feature is the lack of geo-fencing, so you can’t set up boundaries and get alerts if your pup leaves your yard. It also doesn’t come in a small size.

Has won several innovation awardsNot available in small sizes (for 22+ pounds; neck size greater than 11.5 inches)
Reliable location trackingCan’t set up virtual fences or get escape alerts (but they say these features are coming soon)

Whistle GO Explore Health & GPS Review

View on Amazon

The Whistle Health & GPS combines location and health tracking in one device. The real-time GPS location tracking uses the AT&T LTE network and Google Maps and sends you alerts via mobile app or text if your dog escapes the boundaries you’ve set. The live-tracking, however, only updates every 15 seconds, which is a bit slow compared to other products.

The fitness and health features allow you to set alerts for over-scratching, oversleeping, and more. You can also monitor and set activity goals for distance traveled and calories burned. Whistle also includes a free Televet feature (by the VETINSIGHT group), with chat, call, video, and email.

The device comes in three colors and fits most collars, but you can also purchase Whistle’s durable nylon collar that comes in six colors and three sizes, ranging from 14″ to 26.” Whistle also sells a similar GPS and Health device called Whistle GPS & Health + that comes on a collar and is better for small dogs (as little as five pounds). Or, if you just want a health and fitness tracker, you can opt for Whistle Health. Whistle didn’t make our top picks due to complaints about GPS reliability and tech support problems.

Frequently Asked Questions

Pet owners have many questions about smart dog collars, and here a just a few of the most common ones. Don’t see yours here? Ask us in our comments.

What Is A Smart Dog Collar?

At their most basic, smart dog collars or devices that you attach to your pup’s collar connect your smartphone to the collar. Most use GPS and cellular signals to keep tabs on your dog’s activity and whereabouts. You can see this information and more by just going into the app on your phone.

Can You Use Smart Collars With Multiple Dogs?

Yes. However, you’ll need to purchase a separate collar and a separate subscription plan for each dog. Many of these systems allow you to manage multiple dog collars within the app. And some give you discounts for multiple dog collar purchases.

Are Smart Tags As Effective As Smart Dog Collars?

No. Smart tags, like the Apple AirTag or Samsung Galaxy SmartTag, rely on the proximity of smartphones to track them. If your pup has escaped your yard, he would have to come within about 200 feet of a smartphone to find his location — and even then, it only pinpoints that one location. Also, you can’t get real-time tracking, so with a dog on the move, a smart tag isn’t very helpful.

Looking For More Types Of Dog Collars?

If you want to take your dog hiking or camping or you live in a remote area, there are some excellent GPS dog tracking collars that don’t require cell coverage like the ones in this article do. You may want to consider a more affordable and fully functional remote dog training collar than Halo. We also have reviews of light-up dog collars to keep your pup safe at night and personalized dog collars, which are an excellent alternative to flimsy ID tags that can fall off.
