Garmin Alpha LTE GPS Dog Tracker Review
A fast-loading GPS dog collar for outdoor adventures
April 13th, 2026
Home > Gear Reviews > Dog Gear
Our verdict
The Garmin Alpha LTE is a cell service-based dog GPS collar that’s faster, more rugged, and can be more reliable than some traditional dog GPS collars, but is lighter and cheaper than Garmin’s satellite and radio-based GPS dog collars.
We tested the Garmin Alpha LTE over weeks of daily dog walks, hikes, drives, and more to see how reliable the location tracking was. This device is best suited for hunting dogs, or for keeping track of fast, wide-ranging dog breeds that run big. The fast loading times give you a location update as fast as every 10 seconds as long as cell service is available, and it can be paired with existing Garmin dog GPS collars or handhelds to extend their range and reliability.
However, the shorter battery life, lack of advanced activity and health tracking, and collar compatibility limitations mean that it’s not suited for every dog family.
If you’re a dog owner who’s already invested in the Garmin ecosystem, a frequent hiker or camper who doesn’t stray too far off the beaten path, and don't care about sleep tracking and other health-focused dog GPS collar features, this is a simple yet reliable way to stay on top of your furry best friend’s location in the outdoors.

How we tested
We tested the Garmin Alpha LTE during multiple weeks of dog walks, hikes, and other outdoor adventures with their two dogs on the Front Range of Colorado. Outings included local park walks in dense urban areas, trail runs in open-sky prairies, hikes in the Boulder foothills, and trips into the canyons in and around Boulder.
We tested on two different dogs with two different hiking styles, one who tends to be independent on hikes and adventures ahead of her people and another who tends to stay close by, to monitor the reliability of the location tracking. We also used this collar at the same time as other collars, like the Fi Series 3+ and Fi Mini, to cross reference location and activity stats. We also used this collar both as a standalone device and paired with a Garmin satellite collar.
While testing on the trails, we encountered different cell service reliability that affected how accurate the tracking on this device was.
Performance in the field
Location accuracy and speed
The location on hikes during testing was quite accurate. On a hike in Boulder where my dog was wearing both the Garmin Alpha LTE and the Fi, it was more accurate than the Fi, likely due to the faster refresh times. It shows the distance your dog is from you in the app (i.e., 25 feet away or 50 feet away), but because it takes 10 seconds for the location to update, if your dog sprints away from you, it lags at the standard refresh time.
If you’re actually hunting with your dog, or if you just want to keep a closer eye on their location, using a faster update rate is a better option. You can toggle between update speeds in the app.
You also can’t start and stop tracks in the app; you have to physically press the button on the device.
The Garmin Alpha LTE was more accurate about tracking where my dog walked on a hike than the Fi, which had some missing walk data on a switchback.
Here is a screenshot of Fi app on the same switchback, though some data is missing.
Service
Regardless of your phone’s service, this collar works if there is either AT&T or T-Mobile service in the area you’re in. Many GPS collars only utilize one LTE network, and the ones that use two or more are much more reliable. I’ve found that it works even if my phone (AT&T) has low or minimal service.
App usability
The Garmin Alpha app isn’t the most user friendly, and it’s yet another Garmin app you have to download and have on your phone (Garmin, can we have some apps that can manage multiple devices, please?). It’s hard to find tracking features on it, and doesn’t have a user-friendly, navigable vibe like the Tractive and Fi apps do. That being said, Garmin is Garmin. If you’re used to using this brand’s ecosystem, it’s not terrible to figure out. Though there aren’t any bells and whistles to the app—it’s essentially a map that shows your location, your dog’s location, the distance your dog has gone, and previous walks/hikes/hunts. You can toggle between different devices on the app if you have multiple devices..
The arrow on the map (which denotes your dog’s location) doesn’t automatically move on the map in the app. If you stop looking at it for a while, you have to refresh to get back to your dog’s location, as it’s easy for the arrow to go off the map and no longer be visible in the view you have open. Because of this, the app is not great for turn-by-turn navigation.
A big downside of the app is that you can’t start hikes from it. You have to start tracking by pressing the button on the device itself, which can be hard to remember to do.
Also note that the app doesn’t differentiate between driving and walking, so for accurate data, it’s best to start your dog’s tracking right at the beginning of an activity.
Paired performance
Pairing the Garmin Alpha LTE with another Garmin collar (in our testing, the Alpha T 20 and the Alpha 10 handheld) greatly increased both the battery life and the reliability of the Alpha LTE. The location information of your dog can swap back and forth between the satellite info and the LTE info, depending on what’s available, and you can view your dog’s location on either the Garmin app on your phone or on the paired handheld.
Garmin Alpha LTE Features
You have to start each “track” or hike by pressing the button on the device, you can’t start tracking in the app.
App compatibility
The Alpha LTE connects to the Garmin Alpha app, which shows your dog’s location, their past movements, and allows you to add or toggle between multiple devices.
USB-C Charging
The Alpha LTE charges via a USB-C cord, but it requires connecting a separate piece to the actual device in order to connect the charging cord. Losing this small additional piece would mean not being able to charge the device.
Pairing
The Alpha LTE can be paired with other Garmin collars and handhelds to enhance its battery life and reliability. Pairing the Alpha LTE with a satellite collar ensures you always have a connection to your dog, though pairing isn’t required to use it.
Variable speed settings
Users can adjust how often you want the Alpha LTE to update their dog’s location: every 10 seconds, every 2 minutes, or dynamically based on their dog’s activity.
Collar compatibility
If your dog wears a plastic buckle collar or a slip collar, this device won’t fit on it.
The back of the Alpha LTE features two thin plastic holes, meant for sliding a collar through. Unfortunately, traditional buckle collars are too thick to fit through this hole, so it’s largely limited to being used on prong-and-hole buckle collars. It would be much more versatile if it came with an attachment to add onto normal buckle collars.
Understanding GPS dog collar features
LTE is cellular service, like how your smartphone can often still connect to the internet when you’re not connected to wifi. Dog collars that use LTE service usually run off of the major cell service networks (Verizon, AT&T, T-Mobile) and typically require a monthly subscription fee, similar to your phone bill. LTE dog collars rely on cell towers for signal, so they’ll only work if you’re within range of your carrier’s towers.
Satellite GPS dog collars don’t utilize cell towers, and instead connect to satellites in space to track your dog’s location. These kinds of collars are more reliable in wild, remote areas where there’s little or no cell service. They’re typically more expensive upfront than LTE collars, and may require separate handheld devices to function. However, since they don’t use cell service, they don’t typically require a recurring monthly subscription.
Radio connections are between a GPS dog collar and a separate handheld device used to connect to it. Radio connections aren’t always the most reliable in rough terrain or past a certain distance.

Garmin Alpha T 20 Dog Tracking Collar
Price: $300 for collar, $400+ for handheld depending on model
Subscription plan: N/A
Tracking speeds: Dynamic tracking, 30-second location refresh when the dog is not moving, and a 2.5-second location refresh when the dog is in motion
Battery life: Up to 68 hours with standard battery pack
Water resistant: Yes, 1ATM (1 atmosphere of pressure at sea level, or roughly up to 10m of water)
Weight: 8.4 ounces with transmitter, antenna, and collar
Cellular networks used: None, satellite and radio connections
The Garmin Alpha T 20 is a satellite GPS collar that works really well for hikes and camping trips in the mountains, in the middle of the desert, or in other remote places where cell service is unlikely. It’s also one of the only GPS dog collar options on the market that doesn’t require a monthly subscription fee, but it comes with a few caveats.
This collar requires a separate Garmin handheld device to function, and we tested it with the Alpha 10 handheld, which is the cheapest option at $400. This is the main caveat to the cost: even though it doesn’t require a monthly subscription like the Alpha LTE, it does require the large upfront purchase of both the collar and the handheld.
This collar was designed for hunting dogs, similar to some of the features in the Alpha LTE. It has tracking alerts for pointing and treeing if you’re actually using it to hunt, and it works well at further distances, telling you how many yards away your dog is and in what direction. This makes it handy for keeping an eye on wide-ranging breeds, like Pointers and Spaniels, who want to run big.
This collar can also be paired with the Garmin LTE for additional reliability and coverage. If thinking about them as single devices, the T 20 is bigger, bulkier, and more expensive upfront than the Garmin LTE, but it’s better suited for remote areas out of cell range. It’s the winner of best for rural areas in our Bet GPS Dog Collars guide.
Garmin Alpha T 20 Dog Tracking Collar
Device cost: $79
Subscription plans:
Basic plan: $144 every 2 years, or $108 billed annually
Premium plan: $120 billed annually, $168 billed every 2 years, $300 billed every 5 years
Tracking speeds: Between 2 and 60 minutes for default tracking, between 2-3 seconds for live tracking
Battery life: Up to 14 days, but lasted 25 days during testing
Water resistant: Yes, IPX7
Weight: 1.2 ounces
Cellular networks used: LTE CatM1
The Tractive GPS dog collar is the overall winner of our Best Dog GPS Collars guide, and it strikes a nice balance of affordability, reliability, and functionality. The battery life lasted just under a month during testing, and it pairs with a feature-rich app that allows you to see your dog’s activity level, set their goals, set location boundaries and alerts, and more.
This tracker offers fast connection times, and a live tracking feature that updates your dog’s location in the app every 2-3 seconds. This is great for searching for a lost dog, but it does drain the battery much more quickly than the standard setting, which updates the location every two to 60 minutes depending on your dog’s activity.
Tractive taps into multiple LTE networks, so the chances of having service are higher than with the Fi, which only utilizes the AT&T network. The Tractive can tap into more cell networks than the Garmin Alpha LTE, so is generally more reliable, though the subscription costs more monthly than the Garmin Alpha LTE.
This is more of an everyday collar for dog parents who want their furry friend to have an always-on type of device, as opposed to the Garmin options which are geared more towards adventure use only.
Tractive Dog 6 GPS Tracker for Dogs
Device cost: Free with subscription
Subscription plan:
Six months: $99 semi-annually
One year: $189 annually
Two years: $339 biennially
Monthly: $19/month
Tracking speeds: Updates around every 5 minutes by default, but updates every few seconds in live tracking mode (official timing not listed, but a 2025 update made big improvements to update times)
Battery life: Up to three months, but lasted about 10 weeks in testing
Water resistant: Yes, IP68
Weight: 1.3 ounces without the collar
Cellular networks used: AT&T
The Fi Series 3+ is a great GPS collar for everyday use, and came in just behind the Tractive in our dog GPS collar testing. The app feels like a social network for dogs, allowing you to connect with your dog’s friends or neighbors and compare their activity. It’s like Strava, but for your dog.
The companion app also supports a slew of health and activity tracking features (more than any other GPS collar we’ve tested), like steps, sleep tracking, strain rates, behavior tracking, and more.
It’s a lightweight tracker that’s not too bulky for smaller dogs, but it does require you to use either the collar that it comes with, or to purchase a compatible collar or adapter to attach it to. The connection speed to the Fi collar is slightly slower than to the Garmin LTE or the Tractive, and the location data is slightly more inaccurate than both of these, though not in a way that would compromise the safety of your dog if it were lost.
If you want to be highly involved in your dog’s activity and health, this is a good choice.
