What is Fi Smart Dog Collar? A Canine Game-Changer 🐾

A quick note before wasting your time reading this review, The Fi Collar can only connect to the AT&T network in the United States. Therefore, while abroad, the collar cannot remotely track your dog or provide GPS/LTE updates, such as Live Tracking/Lost Dog Mode notifications.

The Fi App can only be downloaded from the US App Store. If you have already set up your Fi Collar in the Fi App and are traveling abroad, your collar will work to track your dog's activity and sleep.

In the digital age, even our four-legged friends are getting a tech upgrade.

Enter the Fi Smart Dog Collar, a revolutionary device that's taking the pet world by storm.

Imagine a collar that doesn't just hold tags and connect to a leash, but also serves as a high-tech hub for all things Fido.

From GPS tracking on an LTE-M network to monitoring your dog's sleep patterns, this smart dog collar is designed to be your all-in-one solution for canine care.

But that's just scratching the surface.

With features like Lost Dog Mode, long-lasting battery life, and multi-owner support, Fi aims to give pet parents peace of mind like never before.

Whether you're at work, on vacation, or simply in another room, Fi keeps you connected to your pup's well-being right from your smartphone.

So, what exactly makes the Fi Smart Dog Collar the talk of the dog park?

How Far Can Fi Track Your Dog?

Are you worried about your wanderlust-infused pooch straying too far? Rest easy! With a Fi Subscription/Membership, the sky—or rather, the cellular coverage—is the limit. Your subscription cost takes care of the GPS/LTE connection when your collar isn't linked to Wi-Fi, the Fi Base, or your smartphone's Fi App. This means you get remote access to your pup's location, activity, and the nifty Lost Dog Mode.

No Boundaries Within the U.S.

The best part? As long as you and your dog are within the United States and there's GPS and cellular (LTE) coverage, Fi offers unlimited tracking. Yep, you read that right—no limits on how far Fi can keep tabs on your furry friend.

Add Multiple Dogs to Your Fi App

Got a multi-dog household? Fi has you covered! You can add an unlimited number of dogs to your Fi App.

In the app, each fur baby gets their own profile and activity reports.

Plus, you can set up customized alerts for each one, which will be sent to your phone and any additional owners linked to the account.

Multiple Dogs, One Screen

While you can't see all your dogs simultaneously on one map, the Live Tab shows each pup's individual location or activity on a single screen.

To switch between your dogs and view their unique stats for Rank, Activity/Sleep, and Profile info, you can toggle back and forth between profiles.

Note: For GPS tracking, each dog will need their own Fi Collar and an active Fi Subscription/Membership.


What's Included With a Fi Collar "Kit" Purchase?

Each kit comes fully loaded with essentials to get you started—minus the smartphone and Wi-Fi, of course.

If you're scratching your head over collar sizes, they have different sizes from X Small to X Large.

Included in the Kit:

  • Fi Module: The brain of the operation.
  • Fi Base: The home docking station.
  • Fi Collar Band: The stylish yet functional band that holds the module.
  • USB Charging Cable: For all your charging needs.
  • Warranty: Peace of mind guaranteed.


When it comes to pricing, Fi Series 3 comes with a $19 monthly subscription, which might be a bit steep for some.

Fi Subscription/Membership

A Fi Subscription/Membership isn't just a side dish—it's essential for unlocking the full potential of your Fi Collar. While a membership is included with your Fi Series 3 Collar Kit, it's optional but highly recommended for Series 2. This subscription is your golden ticket to remote tracking, including pinpointing your dog's location and monitoring activity. Without it, features like Live Tracking and Lost Dog Mode are off the table.

Fi Subscription Cost Breakdown

For those wondering about the Fi subscription fees, here's the scoop. If you opt for a monthly billing cycle, it'll cost you $19 per month. But hey, if you're in it for the long haul, Fi offers some attractive prepay options that can save you some bucks.

Prepay Options:

Duration Cost
3 months $54
6 months $102
1 year $192
2 years $336
Lifetime $599

Is Fi the Right Collar for You? Personal Experience

I've had the Fi Series 2 Smart Dog Collar on my Scruffy, for a few years when we were in the U.S, and it's been a game-changer. The sleep tracking feature was particularly enlightening, revealing that Scruffy was resting well.

The collar was easy to set up, and the app interface is user-friendly. I just hope it works Internationally so I can use it while we enjoy your stay in Dubai.

Fi packs in features but also has some quirks. One of them? You'll need a subscription to enjoy most of its perks.

Considerations for Different Dog Lifestyles

  • Adventure Pups: Fi is waterproof. So, can a Fi collar get wet? Absolutely!
  • Urban Canines: Fi's sleep tracking could be a lifesaver in a noisy city.
  • Senior Woofers: Keep an eye on older pup's health via sleep tracking.

Does Fi require a monthly fee?

Yes, to unlock all features, a subscription is needed.

Pros & Cons


  • Smaller Form Factor: The Series 3 is notably lighter and more compact, making it perfect for small breeds.
  • Quick Location Updates: If your dog goes missing, the collar updates its location every 10-15 seconds in Lost Dog Mode.
  • Stainless Steel Case: Durability is a big plus, especially for those adventure-seeking pups.


  • Works only in the U.S: The Fi Collar can only connect to the AT&T network in the United States
  • Slower Escape Alerts: Not as quick as one would hope.
  • Pricey Subscription: At $19 a month, it's not exactly pocket-friendly.

Can the Fi App Be Used Internationally?

Availability Constraints

The Fi App is a U.S.-centric affair as it can only be downloaded from the U.S. App Store. So, if you're traveling abroad but have already set up your Fi Collar in the Fi App, you'll still be able to monitor your dog's activity and sleep. However, setting up the Fi App from an international location is a no-go.

Note: The Fi Collar is only available for purchase in the United States, including Puerto Rico and the USVI. The brand has plans to expand its reach in the future.

Traveling with Your Dog Internationally

If you're an adventurer taking your dog along for an international journey, keep in mind that the Fi Collar can only connect to the AT&T network in the U.S. While overseas, remote tracking and GPS/LTE updates like Live Tracking and Lost Dog Mode will be unavailable. However, activity tracking remains functional.

Traveling Internationally without Your Dog

If you're globe-trotting while your dog stays back in the U.S., fret not! As long as you have internet access and a Fi Subscription/Membership, you can check in on your furry friend from any corner of the world.
