If you’re a traveling dog mom like me, a GPS dog collar is a must-have. Although Puglo has never once run off on me, it gives me the peace of mind and so much more information than just where he is.
It tells me, in real time, that Puglo’s breathing has settled back to normal after a long walk in the Mexican heat. It picked up on a change in his scratching before I had even noticed he was itching more than usual, which turned out to be the start of an ear infection. It tracks his activity from country to country, so I can see whether our travel pace is wearing him out or whether he is taking it all in stride.
For a flat-faced breed, that kind of health data is so vital.
I have been traveling with Puglo for three years, with long stretches through Europe, Latin America, and Southeast Asia. Along the way I learned that not every GPS tracker is built for the realities of international travel. Some only work on US cell networks. Some have battery lives so short you would be charging them every other day on the road. Some are so bulky they make no sense on a smaller or medium dog.
This guide covers what actually matters when you are choosing a GPS collar for travel, which trackers are worth your money, and the one I use and recommend for dogs like Puglo.
Why You Need a GPS Tracker If You Travel With Your Dog
At home, a lost dog is stressful. In a foreign country, it can be a nightmare.
Picture what losing your dog looks like abroad. You are in a city where you do not speak the language, your dog has no local ID tags, and the people around you may have no idea what to do with a found dog. A microchip is essential, but it only helps once someone has already caught your dog and taken them somewhere with a scanner. A GPS tracker lets you go and find them yourself, right away.
For flat-faced breeds like pugs and French bulldogs, the case goes beyond location. Health-monitoring trackers like Tractive give you passive data on respiratory rate, activity, and even scratching. For a breed that overheats quickly and has a smaller margin for error in the heat, having that baseline while you travel matters far more than it would for a healthier-breathing dog.

1. Tractive GPS Dog Tracker: Best Overall for International Travelers
Price: around $79 for the device, subscription from about $60/year
Battery life: up to 7 days in normal use, less in live tracking mode
Coverage: 175+ countries via multi-network cellular
Water resistance: IP67
Best for: dog parents who travel internationally and want reliable real-time tracking across countries
This is what Puglo wears, and it is the tracker I recommend to anyone who travels internationally with their dog.
What makes Tractive win for travel specifically is the coverage. Instead of locking you into one carrier’s network, it connects to whichever cellular network is strongest wherever you are. We have used it in Mexico and all over Europe, in Spain, France, Italy, Greece, and Germany, and it has worked in every single country.
Live tracking updates every 2 to 3 seconds, which is quick enough to be useful if your dog is on the move. The app is clean and simple, and setting up a geofence takes about a minute.
Location is not the main reason I open the app most days, though. The health features are.
Respiratory rate monitoring. For flat-faced breeds, breathing is everything. Tractive tracks Puglo’s respiratory rate in the background and shows me what is normal for him, not a generic breed average but his own baseline. After long walks in the heat, after flights, after a big day out, I can see whether his breathing is where it should be. That peace of mind is hard to put a price on.
Scratch and itch detection. The tracker logs repetitive scratching. A few months ago it flagged that Puglo’s scratching had spiked over several days. I had written it off as normal pug fidgeting, but the data showed a clear pattern, and it turned out to be an ear infection caught early.
Activity tracking and leaderboards. Tractive tracks his daily steps, active minutes, and rest, and compares him to dogs of a similar breed and size. There is a leaderboard, and I check it constantly. Puglo is weirdly competitive for a dog whose true passion is napping.
What the data tells you as a traveler. When you are moving through different countries, your dog’s routine gets disrupted over and over, with new accommodation, new walking surfaces, and new heat and humidity. Having a baseline for Puglo’s normal activity and vitals means I can tell when travel is getting to him and when he is handling it fine. That is something watching him alone would never give me.
On Puglo specifically, the tracker clips onto his harness and sits comfortably. He is a stocky little dog, broader than most dogs his size, and it does not shift around or bother him. At this point I do not think he even notices it.
The one real trade-off is battery life in live tracking mode. If you are tracking location every few seconds, it drains faster than in normal mode. On a long travel day I leave it in normal mode and switch to live only when I need it. In normal use the battery easily lasts several days.
The Premium plan unlocks international coverage, family sharing, and the extra health features. If you travel abroad with your dog, you want Premium.
2. Fi Series 3: Best for US-Based Travelers
Price: around $149 device, subscription about $99/year
Battery life: up to 3 months (exceptional)
Coverage: AT&T LTE-M network (US-focused)
Water resistance: IP68
Best for: dog parents who mostly travel within the US
The Fi Series 3 gets named the best GPS dog collar overall all the time, and for US use that reputation holds up. The battery life is the headline, up to three months on a charge, which is miles ahead of anything else here. The build is premium, it is IP68 waterproof, and the activity tracking is some of the best around.
The reason it is not my top pick for international travelers is the network. Fi runs on AT&T’s LTE-M, which is excellent inside the US but thin in Europe and unreliable across much of Latin America and Southeast Asia. If your travel is mostly domestic, think road trips across the US, national parks, and long drives with your dog, Fi is a great choice. For international flights with your dog, it is the wrong tool.
I have not tested the Fi Series 3 on Puglo. It does perform well in independent testing for US use, and the battery advantage is real if you are not crossing borders often.
3. Garmin Alpha Series: Best for Backcountry and Off-Grid Travel
Price: $400 to $850+ (device and handheld)
Battery life: varies by model
Coverage: dedicated radio signal, no cellular required
Best for: hikers and campers in remote areas with no cell service
Garmin’s Alpha system is a different animal. It does not use cellular networks at all. It runs on dedicated radio, so it works out in the wilderness where your phone has no signal. If you hike, trail run, or camp in remote terrain with your dog, this is what the serious outdoors crowd uses.
The trade-off is cost and complexity. Alpha is expensive, needs a separate handheld unit, and is overkill for most travelers. You are not going to clip this onto your pug for a walking tour of Barcelona. But if your travels take you into real backcountry, and for some of us they do even with small dogs, it is worth knowing this category exists.
4. Apple AirTag: What It Can and Cannot Do
Price: around $29 (device), no subscription
Coverage: Bluetooth crowd-sourced (Find My network)
I am including AirTags because plenty of dog owners use them, and they get misunderstood. An AirTag is not a GPS tracker. It uses Bluetooth and the Find My network, so your dog’s location only updates when another Apple device is nearby. In a busy city full of iPhones you might get fairly regular pings. In a quiet neighborhood or out in the countryside, updates can be slow or simply not happen.
Apple itself says AirTags are not designed as pet trackers. They can work as a backup, so if someone finds your dog and has an iPhone you may get a ping, but for real-time tracking an AirTag is no substitute for a proper GPS tracker.
What to Look for in a GPS Dog Collar for Travel
International coverage. This is the big one. A lot of GPS trackers run on a single US carrier network, like AT&T’s LTE-M. That is fine in the US but can fail or turn patchy in Europe, Latin America, or Southeast Asia. Look for a tracker that clearly supports multi-network or international coverage.
Battery life. On a travel day you might be nowhere near a charger for 12 to 24 hours. Some trackers drain much faster than you would expect. Check what battery life means in normal use versus live tracking, because those are two very different numbers.
Size and weight on your dog. Most GPS trackers are built with medium to large dogs in mind. If your dog is under 30 lbs, a chunky tracker can be awkward or uncomfortable on a harness.
Subscription and total cost. Almost every GPS tracker needs a monthly or annual subscription on top of the device. Factor that in.
Geofencing and alerts. Being able to set a virtual fence and get an instant alert when your dog crosses it is one of the most useful features for travelers in unfamiliar places. Set the boundary around your rental, the hotel garden, or your campsite.
Water resistance. If you travel anywhere near water, whether that is beaches, boat trips, or rainy places, look for IP67 or IP68 water resistance.
GPS Trackers and Brachycephalic (Flat-Faced) Dogs: What’s Different
If you have a pug, French bulldog, English bulldog, Shih Tzu, or another flat-faced breed, a few things are worth knowing about GPS trackers.
Weight and bulk matter more. Brachycephalic dogs often run warmer and overheat faster than other breeds, so a heavy, chunky tracker adds weight you do not want on them. The Tractive tracker is fairly compact and light for what it does, which is part of why it works so well on Puglo.
The safety case is stronger. Because flat-faced dogs can slip into respiratory distress faster in stressful moments, whether from heat, exertion, or panic, being able to locate them quickly in a lost-dog situation matters even more.
Harness, not collar. I always attach Puglo’s tracker to his harness rather than a collar. Flat-faced breeds should not be in tight collars, and a harness gives the tracker a more secure, comfortable spot to sit. Make sure whatever tracker you choose can attach to a harness, not only a collar.
How I Set Up Puglo’s GPS Tracker for Travel
Before we arrive anywhere new, I set a geofence around wherever we are staying. It takes about a minute in the app. If Puglo slips out of the room, the garden, or the property, I get an alert right away instead of finding out when I go looking for him.
I keep the tracker in standard mode on travel days to save battery, and switch to live tracking when he has more room to roam, like on beaches, in open parks, or on hiking trails.
I charge it every few days as part of our normal routine, usually overnight at our accommodation. A full charge takes a couple of hours, which is easy to work around.
Flying With Your Dog Too?
A tracker covers you on the ground. Getting your dog into the cabin is the other half. My Cabin Guide is the exact system I use to fly with Puglo, from picking an airline compliant carrier to the paperwork each country wants. Grab the Cabin Guide here.
Frequently Asked Questions
Do GPS dog collars work in other countries?
It depends on the tracker. Tractive works in 175+ countries and is the best pick for international travelers. Fi is US-focused. Always check the coverage map for a tracker before you travel.
Can a GPS tracker replace a microchip?
No, and it should not. Microchips are required for international travel with a dog in most countries, and for your pet passport or health certificate. A GPS tracker is an active location tool, and a microchip is passive ID. You need both.
What size dog can use a GPS tracker?
Most trackers list a minimum weight, usually around 8 to 10 lbs. If you have a very small dog, check the device weight and dimensions before you buy.
What is the best GPS dog collar on the market?
For most travelers, Tractive is the best overall, mainly because it works in 175+ countries and adds health tracking like respiratory rate and activity
Do GPS dog collars really work?
Yes. A proper cellular GPS tracker like Tractive shows your dog’s live location, usually updating every few seconds, and it has worked reliably for me across Mexico and Europe
If you travel internationally with your dog, Tractive is the tracker I recommend without hesitation. It works across 175+ countries, sits comfortably on Puglo’s harness, updates every 2 to 3 seconds in live mode, and has turned more than one tense moment into a non-event.
If you travel mostly within the US, the Fi Series 3 is well worth a look for its battery life and build quality.
A GPS tracker is not the only safety layer your dog needs for international travel. It is one of the most useful, though, and once you have had the moment where you needed it, you will not want to travel without it again.
