Smart collars are designed to give dog owners who like to let their pups roam a sense of security. By creating invisible fences and monitoring their location remotely, you can make sure that your favorite canine never gets lost. Additionally, you can monitor their fitness and behavior to make sure they are staying healthy, and even set up an exercise regimen for them.

GPS-powered collars are also great for owners who travel with their dogs, allowing them to easily set up digital fences anywhere in the world they may be, and save a large collection of them.

Our favorite smart collar is Fi’s Series 3 dog collar. This smart dog fence boasts a slew of different functions outside of superior location tracking, including training, fitness, and overall health monitoring. It also provides a variety of subscription options to allow owners to test out whether it works well for their dog.

What We Like
  • Extensive tracking, training, and fitness-monitoring capabilities

  • Monitors sleep-wake patterns

What We Don't Like

The Fi smart collar includes exemplary tracking, training, and fitness-related features. It combines a GPS tracker and an activity monitor. Whether you’re attempting to locate your dog or making sure they are burning sufficient calories, the Fi’s attendant smartphone app has plenty of functionality and customizability to give you detailed and up-to-date information.

When it comes to exercise, the Fi allows you to see how your pup’s activity level stacks up against similar dogs. This allows you to gather the information you need to set their step and calorie-burning goals and figure out the requisite amount of overall exercise they need. There is even functionality to track competitions and races with other animals. The app also tracks your dog’s sleep patterns.

The Fi Collar Series 3 offers non-corrective ways to monitor your dog, allowing you to find solutions other than invisible fences and negative reinforcement training collars. In accordance with guidance from organizations like the American Veterinary Society of Animal Behavior, The Spruce Pets does not recommend collars that use shock or stimulation as a form of punishment. You can read here for more on this policy.

If your dog becomes lost or you are specifically concerned about its location during a given time, you can enter “Lost Dog Mode” on the collar’s app, which will refresh every minute (depending on your service). Outside of the smartphone functionality, the collar itself remotely controlled LED light that activates at nighttime.

The collar is also highly resilient, able to handle 300 pounds of pull resistance; it is also largely waterproof. One charge of the collar lasts approximately three months. It comes in numerous sizes (between 11.5 and 34.5 inches), colors, and styles, with martingale, leather, and biothane bands. To access all of the features of the FI, owners must purchase at least a 1-year subscription, which may be off-putting for some buyers. However, it does come with a 30-day free to get yourself acclimated before making the full investment.

The Millan-designed training regimens on the app include custom verbal commands that can be played through the collar for your pop. Their activity can be monitored in-depth on the app to see if they are getting the balance of exercise and rest that they need.

In addition to providing top-notch invisible fencing and location tracking, it monitors numerous health-and-fitness-related areas, including step goals and sleeping and eating habits.

What to Look for in Smart Dog Collars


Payment for many collars is handled through subscriptions. In the best case, this allows consumers to try out the service before committing to a year-long or permanent investment. In other cases—as with our top pick—you’ll need to commit to a longer period of time than month-to-month to get full functionality out of your collar. But the Fi, as with others, allows for a 30-day free trial period. Owners should check out all available options before making their decision.


At the base level, smart dog collars should provide GPS tracking that can easily monitored on an app, with a reasonable refresh rate. The quality of the GPS technology often informs the collar’s price tag. Most collars also transmit information about fitness, making sure pups are getting the requisite about of exercise and rest. More premium collars will give more detailed health information and include sleep-wake monitoring.


Owners will want to make sure that their smart collar doesn’t sacrifice comfort for technological prowess. Reference whatever sizing guide or recommendations the manufacturers include in the product listing, and make sure you take accurate measurements of your dog’s neck circumference. As with other collars, you want to find a size that allows you to put two fingers between the collar and your pup’s next.

Water resistance

Since smart collars are more likely to be used by dogs that spend a lot of time outdoors, it is extra important that your virtual dog fence of choice can withstand the elements. All of the collars on our list are waterproof to some degree, and the manufacturers provide information about their rating and the amount of water the collar can withstand. More premium options are generally more heavy-duty.

  • What is a smart collar?

    Smart collars are devices that allow owners to track their dog using GPS and cellular signals. They also allow owners to create invisible fences or identify desired radiuses for their pup to stay within. The collars interface with an app where owners can stay up to date with their pup’s slightest movements. The collars also usually include health and fitness tracking, though some apps offer significantly more detailed information than others. Advanced features include sleep monitoring, and keeping track of scratching, licking, and other indicators of potential health issues.
