  • Large: 15.5 to 22 inches long, 1-inch wide
  • X-Large: 20 to 31 inches, 1-inch wide 

LED Light

With a simple command from the Fi App, you can illuminate the collar, making your dog visible in low-light conditions. This feature is invaluable for keeping an eye on your dog in the dark, whether you’re in an open field or along a busy street. It ensures that your furry friend can be easily spotted by you, and more importantly, by others, reducing the risk of accidents.

The LED Light is designed to be bright enough to catch attention without being overwhelming. It strikes the perfect balance, ensuring visibility without discomfort for your dog. Whether it’s dusk, dawn, or the dead of night, activating the LED Light provides an extra layer of safety for your pet.


Constructed from premium materials, the Fi Smart Collar 3 is built to withstand the elements. It’s crafted from a high-strength, woven fabric that stands up to the wear and tear of daily adventures, whether that’s a romp through the woods or a dive into the lake. The IP68 & IP66K waterproof certification means it can handle 30 minutes of full immersion at 1.5m depth and high-pressure water jets, so you can let your dog splash and play without worry.

Built-in GPS Module

At the core of the Fi Smart Collar 3 lies its most impressive feature: the built-in GPS module. This advanced technology provides real-time tracking of your pet’s whereabouts, giving you peace of mind whether they’re exploring the great outdoors or simply roaming the backyard. Plus, with industrial-strength rivets and a full stainless steel body frame, the Series 3 is twice as resistant as previous models, ensuring it stays looking like new for years to come.

The Fi App: Making the Most of Your Smart Dog Collar

The Fi app is the ultimate companion to your Fi Smart Collar, offering a wealth of features designed to enhance your pet parenting experience. With its intuitive interface and user-friendly design, navigating the app is a breeze, allowing you to access all of its powerful tools with just a few taps.

It is readily available for download on both the Apple App Store for iOS devices and the Google Play Store for Android users. This accessibility ensures that regardless of your smartphone preference, you can harness the full potential of the Fi Collar to monitor and manage your dog’s safety, health, and activity levels.

Whether you’re a tech-savvy pet owner or a novice, the Fi app makes it easy to stay connected to your furry friends and keep them safe and healthy.

Live Tracking

Live tracking is a game-changer for dog owners. With just a tap on your phone, you can see exactly where your dog is, in real time. This feature uses GPS technology to keep tabs on your furry friend, whether they’re in the backyard or out on an adventure. It’s incredibly reassuring, especially for those moments when they decide to go on a little unsupervised expedition. Plus, setting up safe zones alerts you the moment they step paw outside designated areas.

The precision and reliability of live tracking can’t be overstated. It updates constantly, so you’re never left guessing your dog’s whereabouts. For families who love to let their dogs explore, it brings a sense of security. Knowing you can find your dog anytime adds a layer of safety to their freedom.

Step Counting

Now, onto step counting. This isn’t just a pedometer for your dog; it’s a window into their daily activity and health. The app records every step, letting you set goals and monitor progress over time. It’s not just about how much they move, but ensuring they’re staying active and healthy. You can even compare their activity levels with other dogs of the same breed, adding a fun, competitive twist.

Understanding your dog’s activity pattern is crucial. The app helps you adjust routines and activities based on the insights you gain. If they’re not hitting their daily step goal, you might decide on an extra walk or playtime. It encourages a healthy lifestyle, not just for your dog, but for you too.

Sleep Monitoring

Sleep monitoring is another standout feature. It tracks how much rest your dog is getting, which is vital for their overall health. Just like humans, dogs need a good night’s sleep to stay healthy and happy. The app provides insights into their sleep patterns, helping you identify any changes or issues early on.

This feature also lets you see the quality of sleep they’re getting. Restless nights could indicate health problems or stress. With this data, you can make informed decisions about their care. Maybe it’s adjusting their bed setup or consulting your vet. It’s all about ensuring they’re as healthy as possible.

Add Family Members

The Fi App understands that pet care is a family affair. That’s why you can add family members to the app. Everyone can stay in the loop about the dog’s location, activity, and health. It’s perfect for coordinating walks or keeping track of who fed the dog last. This shared access fosters a team approach to caring for your furry family member.

Adding family members also means sharing the joy and responsibilities. Everyone can monitor the dog’s achievements, like hitting a step milestone. It’s a wonderful way to bring the family together, united in the care and love for your pet.

Privacy and Security

Lastly, let’s talk privacy and security. In a world where data breaches are all too common, the Fi App prioritizes keeping your information safe. The app uses advanced encryption to protect your data, from your dog’s location to their health stats. You can rest easy knowing your information is secure.

The app also offers customizable privacy settings. You decide what information to share and with whom. Whether it’s family members or your dog walker, you’re in control. This level of privacy and security is reassuring, ensuring that your dog’s data is as safe as they are with you.

All About Battery Life

Battery life is a crucial consideration when choosing a smart collar for your pet, and the Fi Smart Collar 3 excels in this department. With its long-lasting rechargeable battery, this collar ensures your furry friend stays connected and protected for extended periods, giving you peace of mind throughout the day.

Powered by a high-capacity lithium-ion battery, the Fi Smart Collar 3 offers an impressive battery life that can last up to an astonishing three months on a single charge, depending on usage. Whether your pet is a couch potato or a bundle of energy, you can trust that their collar will keep them safe and secure without needing frequent recharging.

Charging Made Simple

When it does come time to recharge, the process is straightforward. The collar comes with a charging base that doubles as a home station. Simply place the collar on the base, and it begins to charge. No fumbling with cords or ports. It’s designed to be as hassle-free as possible.

The app plays a part here, too. It notifies you when the battery is running low. This heads-up means you can plan to charge it at a convenient time, ensuring your dog’s collar is always ready to go. Plus, the quick charge feature gets you out the door faster. A short charge can provide a significant boost, perfect for those last-minute plans.

Expanded LTE Network Reach

Say goodbye to connectivity worries with the Fi Series 3’s revolutionary LTE-M low-power, long-distance cellular network. This innovative technology provides double the LTE network reach, ensuring that even the most adventurous pets can be tracked no matter how far they wander. With LTE-M signal reaching approximately 30% farther than conventional networks and an additional 100% increase in signal sensitivity, you can rest assured that your pet’s location will be accurately detected, even in the most remote areas.

6 thoughts on “Fi Dog Collar Review: Why Every Pet Parent Needs This GPS Tracker”

  1. I also think the Fi Collar is the best one available, but having used it for 6 months, I can say that the 3-month lifespan is not accurate. We go on long (4 miles +) walks daily, and 3 weeks is about average down to 20%. Of course, if you let it go down to 20%, your Lost Dog mode would only last half a day or so.

    The website also states that dog activity is recorded when it is not connected to a phone, base station, or LTE-M, but I have found that to be inaccurate. When walking “off-grid” without my phone, the walk is lost, and not recorded. It took several emails with support for them to admit that.

    Is this a big deal? Not particularly, but the app notes which days you meet the step goal, and has an ongoing competition for all dogs, your dog’s breed, and your state. Missing out on a 40,000 step walk meant that 1) we interrupted our “streak” of days, and 2) we dropped a long way in the rankings. Again, this does not affect anything but my own little competitive streak – our Husky could care less!

    Fi Collar Review
    Terrible customer service & warranty
    We used our 1st Fi collar for 6 months before it went out. They did replace it quickly, but it was a lemon and they have not followed thru to resolve the problem. It is extremely unreliable, goes offline for 40 minutes or more and can’t be relied upon. We spent hours & days going back & forth with Fi, documenting the problems, screen shots confirming the issue, and comparing it to the previous collar in similar situations, but they would not step up and take care of the issue. Their responses are belittling and insulting at best. I can’t’ stress enough that they have a worthless customer service attitude and to avoid them at all costs.

    I SECOND this. The customer service is absolutely aweful. Be prepared to jump a hundred hoops. They claim there is nothing wrong.

    Woud NOT recommend – EVER.
