Review: We tested the best dog trackers against one another - My husband and I rescued our dog Charlie 4 months ago. He’d been badly treated as a puppy and so sadly was still very anxious and skittish. We have been training him and he’s got better but at the start any sudden sounds or noises would trigger him, and he would immediately try to bolt. We live in the suburbs, but have a good sized property. Our yard is fenced all the way round, and all the dogs we’ve ever had have always loved it as they can roam off leash. That is except for Charlie…..who just tries to escape. A couple of close calls later, we realized that no doors could be left open, and someone would always need to keep an eye on him when he’s outside. I was still so worried that I looked into what we could use to track him so that I could have more peace of mind. We wanted to make sure that we got this decision right. So, we tested 3 of the best ones against each other: Tractive, Whistle, and Fi. I don’t typically leave reviews, but my husband said we should as it may help save another dog one day! We tested them over the course of 2 weeks, and focused on the following areas: 1. Location Tracking Accuracy 2. Escape Alerts (when your dog gets out) 3. Devices (size, weight, and comfort) 4. App (ease of use and other features) 1. Location Tracking Accuracy We really wanted a tracker that we could trust, so this was very important to us. We had to make sure that if Charlie was to get out unexpectedly, we would know exactly where he was to go get him. To test this, we did several walks with each of them where me or my husband would take Charlie on a walk away from the property and I would watch it on my phone to see where they were going. Some of these walks were around our neighborhood, and some were on hiking trails that were a bit more rural. Overall, there was some variation in the tracking, with the biggest difference being that the Fi and the Tractive are the only two that offer live location tracking, Whistle does not. Another thing we did learn about all of them though is that they will only be able to work in real time with cell service. We talked to support about this and it turns out that’s how they send the GPS location back to your phone. We thought this was important, and so focused on testing hikes that had spotty coverage to see which tracker would respond best. Fi was the only one that would give updates throughout the walk, even if they were intermittent. It seems that it repeatedly tries to ping the location back to your phone, whereas the others were only able to send some reports later on once we were fully in a cell service area. 2. Escape Alerts This was a quick one. I had my husband leave with Charlie and without his phone and I timed how long before I got a notification that he had left. We were trying to recreate a potential ‘escape situation’. This was the order we got our notifications: 1. Fi - 1 minute 29 seconds 2. Tractive - 3 minutes 47 seconds 3. Whistle - 4 minutes 13 seconds 3. Devices This is getting very long as I type it so I’m attaching some pictures of them alongside each other instead! The Tractive is the only one that attaches to your own collar and you don’t need to swap your collar out for, but the Fi is by far the smallest and lightest of the group. Whistle’s surprised us as we didn’t expect it to go so far back into the dog’s neck. 4. App We actually hadn’t thought about including this section when we first started testing, but after using them all for a few weeks we wanted to include it as they each have some cool features. All these companies did a good job with set up. They all took under 10 minutes to get up and running and were straightforward processes. Running through each of them in more detail below: Fi - tracks their location, activity, health and sleep. This is the only one to track sleep which was really cool to see. It’s also the only one with a built in LED light which was a great add for our nightime walks. It also had the longest battery life of all of them and was the only one that we didn’t need to charge over the 2 week period. Tractive - tracks their location and activity. Mainly focused on location but has a couple of neat activity features. Battery didn’t last very long. Whistle - tracks their location, activity and health. Definitely the most focused on health, and tracks things like scratching and licking. Didn’t find these that accurate though. Hope this helps some other dog moms. After the testing we decided to keep our Fi and return the others and are still very happy with our decision.
Review: Fi 3 - This is the 2nd Fi 3 I've purchased as I needed it for my (at the time of purchase)8 month old puppy that is an escape artist and social butterfly. My 3 year old, Axel has had his for over a year and I really like the peace of mind knowing he's wearing a gps collar. It's really easy to set up and the app is super simple to navigate. If you purchase a longer subscription especially with multiple dogs the value is pretty decent as well. The only issue I have is the collar Fi sends with the gps unit. For larger dogs, or a dog that wears a wider collar I believe they are just not wide enough. Also, the gps unit is attached to the fi issued collar as part of the collar its self similar to how the buckle is attached. I don't like the stress that puts on the unit so I have purchased other collars from fi approved makers that attach the unit on top of the collar. No issues with it falling off my boy's collars and they are ROUGH players both weighing over 80 pounds and Axel thinks he's part fish and has done a ton of swimming wearing his. the "track lost dog" setting has worked brilliantly when Tonka has taken off on me and is running amok through our neighborhood. Not sure on the actual distance range as I live on a dead end road that's probably quarter of a mile long with about 15 houses on larger lots (old neighborhood without cookie cutter houses jammed in next to each other and every house has an actual front and back yard) give or take and I've always located him on our street within minutes of noticing he's escaped. The light you can activate has been a life saver when trying to find him in the dark. Anytime I've taken him to training classes, dog competitions or miles away from "home base" ive been able to look at the route and stops made according to the fi. I also really like the health and sleep tracking and the ability to add other ppl including your dog walker to your dog's profile and they have access to the info. My father and boyfriend are on my dog's profiles. I would definitely recommend fi as a great option for a dog tracker gps.

## Features

- 12 MONTH MEMBERSHIP INCLUDED: This Fi Series 3+ dog GPS collar arrives with a full 12 month membership, so live tracking service is active from the moment you set it up in the app. There is nothing extra to buy on day one and no waiting to get protected. Pairing takes just minutes, and you can invite family members, dog walkers, and sitters to share access so everyone caring for your dog can check the map from their own phone whenever they want.
- LIVE GPS TRACKING WITH NO RANGE LIMIT: Unlike short-range tags that only work when you are close by, this dog tracker maintains continuous 24/7 location coverage wherever your dog goes. If your dog leaves the yard, an instant Escape Alert lands on your phone, and dedicated Lost Dog Mode ramps up location updates so you can follow the trail and close the distance fast. Peace of mind at the dog park, on the trail, and at home overnight.
- HEALTH AND BEHAVIOR INSIGHTS: Beyond location, the collar counts steps, tracks daily activity, and monitors sleep, then translates that data into meaningful trends you can actually use. Compare this week to last, set activity goals, see how your dog stacks up against similar breeds, and notice shifts in rest or restlessness early. It turns everyday walks and naps into a clear picture of how your dog is really doing over time.
- WATERPROOF, DURABLE, AND BRIGHT: The tracking module is protected by a stainless-steel frame with IP68 and IP66K water resistance, so swimming, downpours, mud, and rowdy play are no problem. An integrated LED light keeps your dog visible during dawn walks and late-night yard breaks. Battery life reaches up to three months per charge, which means far fewer charging nights than typical GPS dog collars and less chance of a dead tracker.
- SIZED AND STYLED FOR YOUR DOG: Choose the X-Small size in Blue for a secure, comfortable fit that stays put through daily wear. The tracker module seats firmly in the band so it stays where it belongs during play and adventure, and the collar is designed for all-day comfort. Fi Series 3+ is also compatible with Apple Watch, letting you glance at your dog's location and activity from your wrist without pulling out your phone.

### ⭐ Inaccurate GPS; not reliable for rural areas.
*by S***L on December 19, 2025*

I’ve been exceedingly hopeful about this product for a long time now. When it connects to GPS, it’s helpful for at least getting you in a general range. It does not accurately let you know when your pet has left the safe zone at all. It also does not pinpoint your dog’s location on GPS; it only shows a general location, so you could be 500 to 1000 feet apart, which is a very big distance if you’re in a forest or field without a clear line of sight. It can take 45 minutes to get a notification that your dog has left the safe zone, depending on when it picks it up on GPS. The battery does last a while, but nowhere near the three-month claim. It is sturdy and it does stay on, however. The point of the light I don’t quite understand because it’s not bright enough if you’re looking for them at night. I think it’s just a fancy added feature. The subscription part, where you can see all of the steps that they take, is not really a bonus, the way I purchased it. It was part of a package deal, so I’m not sure if I have to keep it yet. I certainly don’t plan to because it won’t be worth the money for what I’ve gotten out of the product. If you’re looking for something that is going to immediately tell you when the dog leaves, give you a small area, as in less than a third of an acre for a safe zone, and pick up GPS signals in rural areas, you’re going to need to spend a lot more money or find a better product that I may not have found. This is not meant for rural areas or anywhere that has gaps in GPS. You’ll just be hunting for your dog for hours, walking in circles, playing chase, hoping this thing actually leads you somewhere.
