The Best Dog Activity Monitors (Review) 2021

Last Updated May 21, 2021

Everyone knows that dogs need plenty of exercise to keep healthy. Unfortunately, there really is no way you can have eyes on your dog 24/7 to make sure that it gets the right amount of activity levels it needs. What you can do, however, is to use the best dog activity monitor to help you keep tabs of your pet’s daily activities so you’ll know what to do next. Sadly, the market can be unforgiving as it can be flooded with GPS and RF pet tracker knockoffs that do nothing but send you false alarms and frustratingly inaccurate pet information. That’s why we’ve taken it on ourselves to search the market for the 5 best dog activity monitors.

The Best Dog Activity Monitor


The brand new generation of the ever-popular Whistle tracker for pets has had a major overhaul. Most notably, the increased battery life, which has gone from 7 days to an incredible 20 days. This GPS tracker for dogs now plays host to the one of the highest quality options in battery longevity. As well as this, new features have been available, making it easier than ever to find your dog.

A built-in night light makes it easier to see your dog, in heavily wood areas or for those who need to walk their dogs in the dark. Buyers are also able to choose from a wider range of colours, which also act as high-visibility, to ensure your dog’s safety, when you’re out and about. Next, the smaller size is also better suited to a wider range of different dog breeds, while the older version was a little too bulky for toy breeds and puppies.  

When trying to locate your dog, uou can choose from default refresh rates, which sit between 3 minutes and 30 minutes. Naturally, the 30 mins refresh offers greater battery life – but a 24h worldwide geolocation, which works with AT&T, means you can find your dog anywhere. As long as they have the GPS tracker on their collar, of course!

The ideal choice for anyone looking to let their dog have some freedom around the home. This option uses an integrated 3G sim, which triangulates to find out where your dog is, at any time. This isn’t the best feature, however, as it will require a monthly subscription to the service.

Instead, the best feature is its ability to create a virtual fence around a property or area. If the GPS monitor senses that your dog has passed over this geofence, it will send you a notification. Allowing you to retrieve your pup quickly and easily, before they get too far away. This works in combination with the live tracking feature, which provides you with an accurate geolocation of where your dog is, at any time.

On top of this, it also comes with some nifty features, which allow you to track your dog’s overall health. At the same time, it’s completely waterproof. This makes the Tractive dog monitor an ideal choice for those who enjoy getting out and about on adventures, with their dogs. Just be sure to charge your battery before heading out, as this is quite short compared to most other options on our list.

If you really want to monitor your pet’s activity levels including its sleep and rest, the FitBark’s Dog Activity Monitor fits the bill perfectly. Its whimsical dog bone design is an added bonus to augment the stylish collar of your pooch. FitBark works like the FitBit system that most of us are familiar with. This also means that you can customize the health goals for your pooch.

It instantly connects to all Bluetooth devices that have the FitBark app allowing access to a community of FitBark users so you can easily share your dog’s activities and download benchmarking information for your guidance. There are some issues as to the reliability and durability of the unit, however. Some users report of the device no longer working after only several days of use. There are also issues about the difficulty of synchronizing data. For its price, it is quite expensive considering that you don’t even get a GPS tracking solution. Regardless, if you consider the number of those saying good things about the FitBark you’d be expected to get one for your pet, too.

For a GPS pet tracker that is supposed to run on a 10-time award-winning technology, it pains a lot of pet owners to see the overpriced and poorly-designed Tagg GPS Tracker make its way into the collars of their respective dogs. Tagg is a GPS tracker that relies on orbiting satellites for pinpointing the exact location of your pet. There are issues with the tracking capabilities of the Tagg, with many saying it is not real-time at all. And if you happen to have a jackrabbit for a dog, then you’d know that it is utterly useless to rely on a system that lags behind in its tracking capabilities.

For all its downsides, there are a few good ones, too. For starters, it is waterproof and constructed of durable materials. Tagg comes with an app which you can use to monitor your pet’s daily activity levels, making sure they get the right amounts of exercise to overcome the risk of obesity. With these good points which, unfortunately, pales in comparison to the Whistle 3 it really doesn’t make any sense why it’s priced higher than similar systems.

The Link AKC Smart Dog Collar has a lot of similarities with the Whistle 3 and Tagg systems especially in terms of providing for dual functionality in terms of pet activity monitoring and GPS pet tracking. However, the Link AKC sits between Tagg and Whistle 3 when it comes to price; its design is closer to Tagg while its operating performance is closer to Whistle 3. Its main attraction is its lovable design that comes with a tracker unit that matches well with its complementary collar.

One useful feature of the Link AKC is that it alerts you to the ambient temperature of the surroundings where your pooch is currently in. If it is outside the normal temperature parameters it pushes a notice so you can take your pooch to safety. The Link AKC also doubles as a training collar because of its integrated LED light and sound effects that you can remotely control through your phone. It also stores veterinary records as well as sends out reminders for your pet’s health activities. The experiences and moments you share with your pooch can also be stored.

Best Dog Monitor Buying Guide

There are also products that have performed relatively well in that past but their technologies have now become obsolete that they’ve already been overshadowed by flaws in their systems. In our continuing effort to provide you with credible information to aid in your decision-making, we’re sharing this buying guide so you’ll be better-informed of the right dog activity monitor you have to buy for your pet.

What is a Dog Monitor?

As the name implies, a dog monitor is a device that keep track of your dog’s levels of activity based on whether it is moving or not. Well, that is an oversimplified way of describing the complex algorithm that occurs inside the processors of these gadgets. What essentially happens is that different sensors integrated into the device monitor your dog’s health parameters to come up with a fairly accurate picture of its levels of ‘physical activity’. The accuracy and validity of the information on activity levels are, thus dependent on the sensitivity and computing accuracy of the system. If the sensors are not getting the right data then you really cannot expect to generate highly-accurate activity level information.

Check out our article on the Best Dog Gadgets.

Depending on how the dog monitor is designed, it can also include a variety of other functions such as the following.

  • GPS pet tracking

This is one of the most important add-on features to any dog activity monitor as it gives you the ability to pinpoint the precise location of your pooch in case they wander off. It is a lot better than merely relying on Bluetooth or even radio frequency location and tracking capabilities since you can make full use of the extended coverage of GPS systems.

  • Bluetooth connectivity

Since Bluetooth connectivity follows a device-to-device communication pattern, this functionality is exceptional for identifying who is with your pooch any time. It can also work to determine if your pooch is still within Bluetooth range.

  • Veterinary records management apps

Many dog monitors come with applications that allow for the integration of veterinary and other pet-related health records for a more efficient management of veterinary care.

  • Organizer functions

This is now considered a standard in many dog monitors. It allows for the more effective tracking of a dog’s progress in relation to its personal best and compared to other dogs of the same breed.

What Makes a Good Dog Monitor?

Looking at the market you’ll be greeted with a lot of dog monitors that promise a lot of stuff. But the bottom line remains, what makes a good dog monitor? While different brands will have different interpretations of what constitutes the essentials, here are a few things that separate the best from the mediocre ones.

  • Accurate

You want a device that can give you highly accurate information about your dog’s activity levels and not just some results coming from dubious algorithmic processes. Highly accurate data can help you devise a more appropriate plan of activities for your pooch.

  • Tracks health parameters

While activity level monitoring is helpful, the addition of other health and veterinary parameters should give you a better picture of your pet’s overall health status. This provides exceptional feedback on whether you’re doing great as a pet parent or not.

  • Easy to use

No one likes very complicated processes and operations. If you can get the information that you want in a few swipes of your smartphone or in as little effort setting up the activity tracker on your pet, then it should be an excellent buy.

  • Durable and waterproof

What’s the use of an activity tracker if it can only be used by your pet indoors or that it won’t even last a few minutes of rough play? Durability and weatherproofing are two properties that all dog monitors should have.

Which Pet Tracker Should You Pick – GPS or Radio Frequency?

When it comes to pet trackers, you’re essentially left with 2 fundamental designs: GPS or radio frequency. Technically your choice actually depends on how far off your pooch will typically venture on its own. If your dog is not really known for venturing very far from you, then an RF pet tracker should suffice. However if your pooch runs faster than a fox and ventures way further than a lioness, then a GPS tracker should be in the offing. While both rely on a clear line of sight to establish communication between the receiving unit and the base unit, the range in a radio frequency unit is more limited than that of a GPS. Most RF units have a working radius of up to several hundreds of feet. For a GPS unit, you’re looking at several hundred miles. Naturally, GPS trackers will be more expensive so you might also want to factor that in your decision.

Monitoring your pet’s activity levels is essential for keeping them healthy and fit. While you may not be able to do this personally on a round-the-clock basis, you can use any of the products we featured in this post to help you design a more purposeful activity for your pet. However, we do recommend getting the unit with an integrated GPS pet tracker to get the most value for every penny that you spend.
