The Fi Dog Collar Series 2 is a GPS smart collar for your dog, which uses a combination of Wi-Fi and GPS to track your dog’s location, as well as tracking the number of steps your dog has taken in the day, and as of 2021, it also offers dog sleep tracking. Perhaps obviously once you think about it, the ‘Fi’ in Fi Dog Collar is pronounced the same as the Fi in ‘Fido’ or Wi-Fi.
For this Fi Collar review, I initially wore the device every day for two months straight (spoiler alert, I’m still wearing a Fi collar more than a year on). Keep reading this Fi Dog Collar review to find out what I (and my humans) think about using this GPS Fi Collar in real-world, everyday scenarios.

How does the Fi Dog Collar work?
The Fi Dog Collar uses the AT&T network for locating your dog when he or she is out of the house alone, as well as Wi-Fi and Bluetooth-based safe zones, which would typically include:
- Your home – where your dog’s Fi Collar base station should be plugged in and connected to Wi-Fi
- Proximity to you – or more specifically, within Bluetooth range of your phone
- As needed, additional base locations (such as your office, or dog sitter/parents’ home), and the phones of other trusted people, such as your dog walker, friend, spouse, kid, etc.
What is the Fi Dog Collar made from?
The Fi Dog Collar has a nice, solid construction to it. It’s definitely a lot heavier than my regular webbing collar, as it has a matchbox-sized GPS unit and durable metal hardware, including a quick-release buckle and loop for dog tags and leash attachment. My favorite dog running leash connects very nicely to it.
Fi state that their collar is chew-proof and generally dog-proof – and it comes with a 1 year warranty, which is reassuring. I’ve worn mine pretty much every day for the last couple of months and it has picked up a few light scratches as you can just about see in the photos, and I’m sure it will pick up a few more scratches as I spend more time on the trails and nosing into brambles, that sort of thing.
If you do damage your Fi dog tracking collar’s fabric, or you want to change the color, you can buy a replacement nylon webbing part for less than $30. I’d be tempted to go for the jazzier and higher-visibility yellow Fi collar if I was to need a new one.
Due to the weight, I didn’t start wearing my Fi Dog Collar until I had grown to 30lb and was a 4+ month-old pup, as my parents didn’t want me wearing a heavier collar when I was younger and smaller – plus, I was more of a baby dog at that point so I wasn’t able to go out on as many adventures as I do now.
Is the Fi Dog Collar waterproof?
Yes! If you’re going to invest in a Fi collar dog GPS tracker and pay a lot more than a regular dog collar to buy one, then you definitely need it to be waterproof and stand up to not just rain but your dog jumping into ponds, lakes, puddles, etc etc. I’ve tried drowning it in a lake when my humans took me SUP’ing, but haven’t been able to.
It’s personal preference but I prefer to have my baths naked, so I haven’t tried it in the bath, but if the Fi collar folks say it’s waterproof, then I guess you could have a bath with it on, too (but why would you feel the need to, unless you hate baths that much that you may escape from home mid-bath?).
How long does the battery last on the Fi GPS Dog Collar?
One of the outstanding features of the Fi Dog Collar is that the battery can last up to three months between charges. The three months battery life is based on if your collar does not spend much time outside of the range of your home base station, i.e. you don’t get out much.
The length of time the Fi collar’s battery lasts naturally depends on how active a dog you are and how much time you spend out of the range of the house base station, which will require the collar to use more battery power in connecting to your parents/dog-walker’s phone via Bluetooth, and picking up GPS signal when out of range of their phone and your home base (if you have a Fi subscription to effectively turn your Fi Dog Collar into its own mobile device – more on that, later).
As a Border Collie, and therefore pretty much by definition one of the most active dog breeds, I do drain the battery quicker than the stated three months maximum battery life – at least based on my first couple of months of using my Fi collar dog GPS tracker – my parents charged it after around 8 weeks. But still, 8 weeks for a collar worn by a busy puppy doing 2-3 walks a day is a long time to go between charges (especially when considering my parents have to charge their smartwatches pretty much daily!).
What is a ‘safe zone’ for the Fi Dog Collar?
The Fi Dog Collar comes with a Fi Base, which is also used to charge the Fi collar.
Safe zones are defined by a perimeter range around the Fi Base, as well as when the collar is away from home but within bluetooth range of a designated owner/dog-walker. Having the home safe-zone being designated by the Base location helps save on battery life as the Fi collar dog GPS tracker doesn’t need to pick up and track from GPS when it knows it’s within range of the base station, which is a neat feature.
You set up the Base and the designated humans using the Fi app. Designated humans may include family members, your dog walker and any one else who may be alone with your dog. Designated humans need to have their phone with them and the Fi app installed for this to work.
If your dog is near one of your designated owners/walkers when out of the house, then you can then get notified via the Fi app notification and / or text message when they leave the safe (home) zone for a walk with that person. For example, the message my parents receive when my Dad takes me out for a walk is ‘Kepler just left home with Alastair’.
If I was to leave home without someone my parents have set up in the Fi app, or if the person walking me does not have their phone with them, the message my parents receive will just say ‘Kepler just left home’. If you receive a notification like this, and you know your dog should not be out on a walk somewhere, then this may be the trigger you need to set off the ‘Lost Dog Mode’ and start tracking down the sneaky canine if they’ve escaped home.
For me, the message comes through within around a minute of leaving the house – I have to be outside of the safe-zone perimeter, which extends beyond our front door (as our current home is not large) so there is sometimes a lag between me leaving the front door and triggering the notifications that I have left home.
It’s also worth noting that your dog is frequently at another location (such as a friend or family members’, pet sitters’, office, etc.) it may be helpful to have an additional Fi Base (currently $39) to avoid having to transport your home Fi Base and reconfigure wifi to each location. Also, if you have a large house/property then you may also benefit from having more than one base station (assuming each base station can connect to a wifi network – i.e. you can’t get one to have at the end of the garden if that’s out of range of your Wi-Fi).
How does the Fi Collar dog GPS tracker ‘Lost Dog Mode’ work?
If you activate Fi Collar’s ‘Lost Dog Mode’ using your Fi app, then this turns on live location tracking on your dog’s collar to help find him or her [note: you need to have a Fi subscription so that effectively your Fi GPS Collar acts as its own cell phone, to enable the Fi collar to be tracked using phone signal for GPS, when your dog is not with an owner].
Lost Dog Mode also activates a red pulsing light on your dog’s Fi collar to help make them easier to spot in the dark, and sends a location notification to you every minute so you can track them down. When we tested it (by having my Mom take me out without her phone, so it looked like I had taken myself for a walk), the GPS was accurate to within around 50ft or so. This was a fun game of ‘find me’, but it could save my life if I was to escape.
I expect the accuracy would vary depending on how strong and reliable the cell service is in a location where your dog goes missing, but I would hope that it gets my parents close enough to me that they can either see me at a distance and / or call me back to them. It’s also worth noting that because the Fi collar dog GPS tracker relies on me being within cell service, it won’t be able to track my location in an area without phone signal.
When in Lost Dog Mode, the battery life of the Fi collar dog GPS tracker is up to two days, as it’s using GPS signals to refresh the location status every minute, which consumes a lot more battery juice than regular use.
Does the Fi Dog Collar dog tracking device have a light?
Yes! One feature that my parents love is that at the push of a button on the Fi app, my Fi collar lights up with a pulsing light. You can choose from 7 different colors including blue, pink, yellow and green. It’s just one one part of the Fi collar so not anything super-bright or flashy, but it’s a nice feature for night walks, especially if it’s very dark where you are, you’re near an area with cars or other people, and you’re a dark-colored dog who is harder to see.
Activity Tracker for Dogs: Using the Fi GPS Collar to track your dog’s steps
A nice feature of the Fi GPS Dog Collar is that it’s not just a dog GPS tracker to find your dog’s location. My Fi collar dog GPS tracker also counts my steps and summarizes how many steps I did on each walk. This way, my humans can use the app to set a daily step goal for me, and track my daily step activity in the Fi app.
I gather there is no proven science specifying what is a ‘healthy’ amount of steps for a dog, and of course that would vary between dogs’ individual needs. But it’s a nice feature, and like a human’s smartwatch step tracker, can be used as a prompt to make sure that if you’ve had a quiet few days and not taken your pup out for as much activity as normal, you may want to step it up.
Equally, and importantly for a growing boy such as myself, the goal can also be used as a target to stay BELOW – ie. So that I don’t get too much exercise, as I need to make sure I don’t over-use my growing puppy body and risk an injury.
One nice feature that my parents find entertaining is the ranking by breed, which tracks the last month of steps and compares you to how other dogs of your breed are doing with their step count. There are options to set yourself up as a mixed breed, so I’m in a category with Border Collies and Border Collie mixes, for example.
Sleep tracker for dogs: Using the Fi Collar to track your dog’s sleep
An update to the Fi collar software in mid-2021, the Series 2 also tracks your dog’s sleep, if you feel it’s safe to leave your dog’s collar on them overnight.
Like with people, getting enough sleep is important for dogs health, both long-term, as well as short-term to help them recover from intensive workouts and the day’s activities. This is especially true for puppies and young dogs, especially dogs like me, who will move around all day if not given the opportunity to learn to relax and sleep.
The Fi sleep tracker shows how much time during a day your dog is sleeping, napping or awake, and shows this by hour, day, week and month.
Using the Fi app
My parents like the Fi app and find it clean and easy-to-use. Some may say the app is overly-simplistic in terms of activity tracking as it mainly tracks your dog’s steps and GPS location points (as well as acting as a dog sleep tracker), but they like the easy-to-use functionality – and – hey, I’m a dog, not a pro athlete (yet), so I don’t think anyone in my family feels the need to get much more granular in terms of the details of my activity just yet, tracking steps and my sleep is enough.
In the future, though, perhaps a good direction for Fi to investigate would be heart rate tracking – imagine the possibilities! We all know that for humans doing ‘X amount of exercise at a heart rate within a given range’ is better than just doing ‘X steps in a day’, so this would be an awesome feature. Not sure how they’d get a good heart rate reading past all my fur, though…
How much does the Fi Dog Collar cost?
The Fi Smart Dog Collar costs $149 at the time of writing this Fi dog collar review – that includes either a grey or yellow collar and the main matchbox-sized GPS device mounted on it, together with the base station that you plug in at home. If you use our code 4C83FW via this link you’ll receive an extra band free of charge which is nice if you like to mix-up your look to keep your instagram followers entertained. 🙂 Use our exclusive coupon code TK25 via the link below to get $25 OFF your Fi Collar order.
You may also wish to purchase a Fi Collar subscription, as this is needed to access all the GPS-specific features used by the Fi collar, including the important ‘lost dog mode. The subscription costs $99/year, or $8.25/month, and gets your dog’s collar added as a device to the LTE-M low power cellular network, which was specifically designed for such devices, and offers 20-30% more cellular coverage in the US than 3G networks. My parents have this subscription, so this Fi collar review is as in-depth as it could be, covering the GPS-specific features of the Fi Collar dog GPS tracker.
As of 2021 you can also buy the Fi dog collar online at Chewy.com, although you won’t be able to use our discount code on their site.
Do you need a Fi Subscription to use the Fi GPS Dog Collar as a dog tracker?
A subscription gives your parents access to the full capabilities of your dog’s Fi collar – allowing for remote access to your location and activity. The cost of the subscription covers the GPS/LTE connection to the Fi collar – effectively, making it into a mobile device.
Without a subscription, the Fi collar will still function – but if you go outside the range of your peoples’ smartphone or your Fi Base, then nobody can use the Fi Collar’s functionality to locate you. This kind of defeats the point of one of the key functions of the Fi Dog Collar, that is, so that people can track you and have a much better chance of finding you if you wander off, so it seems that if you are considering getting your dog a Fi GPS collar, then you should get the subscription.
What cell / mobile phone network does the Fi Dog Collar use?
The Fi Dog Collar uses the AT&T network for locating your dog when he or she is out of the house alone, as well as Wi-Fi and Bluetooth-based safe zones. Your own mobile phone does not have to be on the AT&T network for your Fi GPS Collar to work, the two are unrelated.
How do you remove the Fi GPS Dog Collar’s metal clips?
You may want to remove the metal clips from the Fi collar dog tracking device so that you can switch out the collars that you attach the Fi collar to. Quite a few dog collar brands are making ‘Fi-compatible’ collars, which is pretty nice if you want a specific custom collar for your dog but also want to have the Fi device attached to it. We’ve been asked this question a lot, and it’s most easily explained in a video – see below for a demonstration of how to detach those clips.
My parents also attached my Fi dog tracker unit to my favorite Ruffwear collar, which isn’t a ‘Fi-compatible’ collar but they engineered it to work! Have a read of this post if you’re curious how to use the Fi collar dog GPS tracker with other brands of collar.
Can you use the Fi Collar for cats?
No. It’s far too big for a pet cat to wear, unfortunately – because a Fi collar for a cat would be great and I’m sure my feline brothers would like to wear their own gadgets and look as cool and high-tech as me.
