# What to know before you buy

Updated November 10, 2026.

## The best GPS dog fence without a subscription

PawTronic Pro Series 2 is the best pick with no subscription. You pay once, and the fence, the app and all six layouts stay free for as long as you own it.

Four other collars also run the fence with no plan. SpotOn draws a custom fence with no plan, but it costs $999. Dogtra costs less, but it needs over 3/4 acre and limits wear to 6 to 8 hours at a time. Premier Pet and Invirox skip the app and can only draw a circle. PetSafe sells a no-plan Guardian GPS too, for dogs over 25 lb. Halo and the PetSafe Guardian GPS 2.0 both need a plan.

A plan buys you a dot on a map. It doesn’t make the fence hold any better. I wouldn’t pay monthly for a fence. If you want a dog that stays home, skip the bill. No-subscription fences, compared.

## How accurate is a GPS dog fence?

A GPS fence is accurate to within a few feet under open sky. That’s why it needs room, and why the line belongs well back from danger. GPS.gov puts typical phone GPS accuracy at about 16 feet under open sky. Near buildings, bridges and trees, it gets worse. The makers’ own numbers sit in the same range:

| Maker | What it says about drift | Buffer it asks for |
|---|---|---|
| SpotOn | 3 to 10 feet near tall structures or heavy forest | 15 feet from a road |
| Halo | 7 to 10 feet is normal | 15 to 20 feet from your home or a road |
| Dogtra | Usually accurate within 3 to 15 feet | Not stated |
| PetSafe | Weaker under very dense trees | 25 feet per story from buildings, 25 feet from busy streets |

I plan for the strictest number on that list. Keep the line at least 25 feet from a road. Under trees, the tone can come earlier than it does on open ground. An early tone keeps your dog farther from danger, but it also shrinks the yard, so walk every line before you trust it.

Sidenote: Take the collar off indoors. Walls and roofs block the satellites, so a collar inside the house can lose its place.

## GPS vs wireless and in-ground fences

A GPS fence uses satellites and a map. A radio wireless fence uses a base unit indoors, and an in-ground fence uses a buried wire. That one difference decides where each one works.

| Feature | GPS fence | Radio wireless fence | In-ground fence |
|---|---|---|---|
| What makes the boundary | Satellites and a map in an app | A base unit plugged in indoors | A wire buried around the yard |
| Setup | Charge the collar, draw on a map | Plug in the base unit | Dig a trench around the whole line |
| Shape | Drawn on a map (PawTronic: circle or 8 points) | A circle around the base | Wherever you lay the wire |
| Yard size | Half an acre and up | Small to medium yards | Any size |
| Edge precision | Within a few feet | Can wobble near metal and walls | Follows the wire |
| Take it with you | Yes | Only with the base unit and power | No |
| Stops working when | The battery runs flat | The power goes out | Digging or mowing cuts the wire |

People call any buried-wire system an "invisible fence", but Invisible Fence is a brand name. On a small lot, a buried wire or a radio fence is the better tool. From half an acre up, a GPS fence has nothing to bury, and it’s the only kind you can redraw in minutes. How GPS fences work.

## How to set one up

You can set up a GPS fence in about half an hour, with no tools. These are the steps for PawTronic, and most GPS collars follow the same order.

- ### Charge the collar Charge it fully before the first setup.
- ### Pair it outside Install the free app and pair the collar in the yard, where it can see the sky.
- ### Pick a circle or draw your shape Set a circle with a radius from 82 to 7,000 feet, or place up to eight points on the map.
- ### Pull the line back from danger Leave at least 25 feet between the line and any road.
- ### Save it to the collar Save the layout, so the collar carries the line.
- ### Walk the boundary Carry the collar along the edge, and listen for the tone where you expect it. Move any point that’s off, then save again.
- ### Flag it and fit the collar Put training flags along the edge, then fit the collar so two fingers slide under the strap.

Step 6 is the one people skip, and it’s the one I’d never skip. If the tone comes early near trees, move those points out before your dog wears the collar.

## How to train your dog

Most dogs start turning at the cue within a few days, and PawTronic owners report one to three. Full training takes about two weeks. Keep each session to 10 to 15 minutes, on a leash, with treats. Flags matter here, because your dog needs something to see before the collar makes a sound.

- ### Days 1 and 2: tone only, on a leash Walk toward a flag. When the tone sounds, turn back with your dog, then praise and reward.
- ### Days 3 and 4: add vibration Switch to sound plus vibration. Keep the leash on, and reward every turn back.
- ### Days 5 to 7: add distractions Toss a toy near the edge. Your dog should now turn at the cue on its own.
- ### Week 2: off leash, while you watch Pull the flags out a few at a time, once your dog turns back every time.

Static is optional, and you may never need it. Owners in PawTronic’s reviews report dogs that learned the line on beep and vibration alone. I’d give any dog a full week on tone and vibration before I even look at that setting. PawTronic asks owners of small or young dogs to stay on sound and vibration. It also wants dogs over six months old, and its manual limits wear to 12 hours a day.

## Terms explained

- **GPS and GNSS**: Satellite positioning. GPS is the US system, and GNSS is the umbrella term that also covers Galileo, GLONASS and BeiDou.

- **Geofence**: A boundary drawn on a map. A GPS fence is a geofence that the collar enforces.

- **Drift**: The few feet a GPS position wanders, even when the collar sits still. Trees and buildings make it wider.

- **Dual-frequency GPS**: A receiver that reads two satellite signals (L1 and L5) to cut errors near trees and buildings.

- **Alert modes**: How the collar cues your dog at the edge: a tone, a vibration, or both, with optional static.

- **Static correction**: A short electric pulse from the collar’s contact points. It’s optional on every collar in this guide.

- **IP67**: Dust-tight and safe under 1 meter of water for 30 minutes.

- **Radio wireless fence**: A fence made by a base unit indoors that sends out a circular signal.

- **In-ground fence**: A wire buried around the yard that signals the collar. Often called an invisible fence.

Your dog got out again. Maybe it was the gap under the gate, or a deer at the tree line. Now you’re holding a quote to fence three acres in chain-link, and it’s a big number. A GPS fence skips the posts and the trench, but the seven collars people buy differ in three ways. Some need a monthly plan. Some can only draw a circle. And some need more land than you have. So we compared all seven on the same points. Here’s what we’d buy, and why.

## All 7 compared

Only one collar under $300 draws a custom shape from half an acre with no plan: PawTronic Pro Series 2. Here’s how all seven line up.

| Collar | Price | Plan for the fence | Boundary | Smallest yard |
|---|---|---|---|---|
| SpotOn Nova | $999 | None (tracking $9.95/mo) | Drawn or walked | 1/3 acre |
| Halo Collar 5 | $524 | Required, from $9.99/mo | Posts placed on a map | Fences from 900 sq ft |
| Dogtra GPS Fence | $199.99 | None | Up to 25 posts, or a circle | Over 3/4 acre |
| PetSafe Guardian GPS 2.0 | $449.99 | Required, $9.99/mo or $99/yr | Up to 50 saved fences | 0.5 acre |
| Premier Pet GPS | $139.99 | None | Circle, set on the collar | 3/4 acre |
| Invirox GPS | $139.99 | None | Circle up to a 999-yd radius | Not listed |

## 1. PawTronic Pro Series 2: best overall

PawTronic Pro Series 2 keeps your dog inside a line you draw on your phone. Then it stops needing your phone. We rank it first because it covers 0.5 to 200 acres, bends to fit odd-shaped land, and never asks for a plan.

Here’s how the first week goes:

- Charge and pair. The collar charges over USB-C (the same plug most phones use) in 2 to 3 hours. It pairs with the free Linked Paw app over Bluetooth, and pairing works best outside under open sky.
- Draw the line. A circle is the quick option, but on an odd-shaped lot it can cut across a road or a driveway. That’s when the custom shape helps. Eight points on the map let the line follow your lawn, a tree line or a creek.
- Save it to the collar. The collar holds up to six layouts. That means one collar can carry your home line, the barn and a cabin.
- Walk it, then train. Carry the collar along the edge before your dog wears it. Then start with short sessions on the tone alone. One owner in PawTronic’s reviews needed two 10-minute sessions.

Your phone can sit charging in the kitchen all afternoon. The fence keeps working anyway. PawTronic saves the boundary on the collar, not the phone. The alert stops the moment your dog steps back inside.

No plan, no phone nearby, and the collar still carries the line.

PawTronic’s owners report the same kind of results. The collar holds 4.7 out of 5 stars from 285 reviews on its store. One owner fenced about 75 acres of farm for a rescue dog that chases bikes.

One collar costs $278.99, with free shipping, 30-day returns and a 1-year warranty. Each dog wears its own collar, so the packs help. A two-collar pack takes $55.78 off the pair. A three-collar pack takes off $125.52.

### Pros

- No plan ever, and a free app
- Eight-point shape fits odd lots
- Works with your phone left inside
- Fits dogs from 7.9 lb

### Keep in mind

- Charge it overnight, like your phone (up to 36 hours of GPS standby).
- It’s a fence, not a tracker, so it shows no live dot.

## 2. SpotOn GPS Fence (Nova Edition)

SpotOn is a no-plan GPS fence for properties from a third of an acre to more than 100,000 acres. It’s also the priciest collar here, at $999.

You can draw the fence on a map, or walk the line with the collar and let it record your path. Inside the fence, you can add keep-out zones around a pool or a garden.

SpotOn does ask for a fence at least 80 feet wide at its narrowest point. So a long, thin side yard won’t fit. It also asks for a 15-foot buffer between the fence and any road.

Near the line, the collar plays two warning tones. They start about 10 feet inside the line. Next comes a vibration, and then static if you turn it on. (It has 30 static levels.) The collar picks up four satellite systems on two bands, and it has a Forest Mode for tree cover.

A charge lasts at least 33 hours with tracking on. Then the collar refills in about an hour, so a quick top-up in the morning works.

The fence needs no plan, and it needs no cell service or Wi-Fi either. Tracking is the part you pay for. Live location and escape alerts cost $9.95 a month, or $101.88 billed yearly. Each dog needs its own collar and its own plan, and SpotOn takes $100 off each extra collar.

The collar fits dogs from 15 lb, with necks from 10 to 26 inches. SpotOn gives you a 90-day money-back return. You also get a 1-year warranty with one accidental-damage replacement.

### Pros

- Covers 1/3 acre to 100,000+ acres
- Draw the fence or walk it
- Keep-out zones inside the fence

### Cons

- $999 for one collar
- Fence must be at least 80 ft wide

## 3. Halo Collar 5

Halo puts a GPS fence and a live tracker in one collar, and it runs on a monthly plan. You pick that plan before the collar can join your account. Without a plan, the fences don’t work.

The Bronze plan costs $9.99 a month and holds 5 fences. Silver costs $14.99 a month for 20 fences. Gold costs $19.99 a month for unlimited fences. Every plan includes cell data, so your dog’s live position shows in the app, and it updates four times a second.

You build a fence by typing an address and tapping posts onto the map. A fence can be as small as 900 square feet. But Halo’s help center asks for 15 to 20 feet between the fence and your home or a road. The same help center calls 7 to 10 feet of drift normal.

Halo’s collar cues with sound, vibration and optional static. If your dog keeps going, the feedback keeps rising until it turns back.

A charge lasts up to 48 hours. Halo tells owners to take the collar off and charge it every night. The collar is IP67, which means it can sit under a meter of water for half an hour. It fits dogs over 10 lb and 5 months old. Its strap runs from 8 to 30.5 inches, the largest neck size listed here.

Halo Collar 5 costs $524 on sale, down from $599, plus the plan. Over three years on Bronze, one dog comes to $883.64. By year five, the plan alone has cost more than the collar. Halo gives a 90-day money-back guarantee, less $25 for shipping, and a 1-year warranty.

### Pros

- Live tracking four times a second
- Fits necks up to 30.5 in
- Fences from 900 sq ft

### Cons

- Fences stop without a paid plan
- Gold plan costs $19.99 a month

## 4. Dogtra GPS Fence

Dogtra keeps the price low at $199.99, and it needs no subscription. Every app feature comes with the collar.

You draw a custom fence with up to 25 posts, or a circle from 12 meters to 4 kilometers across. The app keeps a main fence plus two backups, and it stores up to 30 boundaries. Dogtra asks for more than 3/4 acre. It puts its own accuracy at 3 to 15 feet, and its warning zone starts 5 to 15 yards inside the main fence.

The phone and collar talk over Bluetooth. That keeps the plan at zero, but alerts reach your phone only within 33 feet. It also means Dogtra shows no live location. Once you’re back in range, the app’s route history shows where your dog went.

You get four settings: steady stimulation, vibration, tone, or none. Stimulation runs from level 1 to 100, so you can start very low. Dogtra rates the collar IPX9K, a rating for high-pressure water jets.

Dogtra’s product page lists dogs from 15 lb, with necks of 10 inches and up. The manual limits wear to 6 to 8 hours at a time, so it isn’t an all-day collar. One phone pairs with up to 3 collars, which covers most homes with more than one dog.

Dogtra doesn’t list the battery runtime. The collar takes 3 hours or more to charge, so plan to charge it overnight. It carries a 1-year warranty.

### Pros

- $199.99 with no plan
- Custom fence or a circle
- Main fence plus two backups

### Cons

- 6 to 8 hours of wear at a time
- No published battery runtime

## 5. PetSafe Guardian GPS 2.0

PetSafe Guardian GPS 2.0 adds live tracking to PetSafe’s GPS fence, and it fits yards from half an acre. You can save up to 50 fences, which helps if your dog travels with you.

Setup needs 2.4 GHz Wi-Fi, so set it up near your router. PetSafe wants fence posts 25 feet per story from any building. So a two-story house needs 50 feet of clear space around it. Opposite sides of the fence need 35 feet between them. PetSafe also says the collar works best without dense tree cover.

The collar uses dual-frequency GPS. It reads two satellite signals, which cuts errors near trees and buildings. It offers tone, vibration and 10 levels of static. PetSafe lists up to 70 hours on a charge. Its user guide limits wear to 12 hours a day, and it says the collar may be too large for dogs under 10 lb.

The plan costs $9.99 a month or $99 a year, and the collar needs cell service for live tracking and alerts. Without service, it still holds the stored fence. Each dog needs its own collar and its own plan.

PetSafe also sells the original Guardian GPS with no subscription, for the same $449.99. That version uses a plugged-in base unit and asks for 3/4 acre. It fits dogs over 25 lb.

Guardian GPS 2.0 costs $449.99 plus the plan, so the first year on the yearly plan comes to $548.99. PetSafe gives a 45-day return window and a 1-year limited warranty.

### Pros

- Up to 50 saved fences
- Live tracking on the plan
- Dual-frequency GPS

### Cons

- Plan costs $9.99 a month
- Needs 2.4 GHz Wi-Fi for setup

## 6. Premier Pet GPS Dog Fence

Premier Pet keeps the whole setup on the collar. You set a circle on its small screen, with no app and no plan.

PetSmart sells the collar for $139.99, down from $159.99. Radio Systems Corporation, the company behind PetSafe, owns the brand.

The circle needs a yard of three-quarters of an acre or more. It’s the only shape this collar draws, so the line can’t bend around a driveway or follow a field edge. On a long or L-shaped lot, a circle that fits the front lawn leaves the back outside the line. A square lot with the house in the middle suits it better.

You pick one of three settings: tone and vibration, small-dog static, or large-dog static. When your dog walks back in, the collar stays quiet. So coming home never earns a correction.

The collar fits dogs from 20 lb, with necks from 12 to 25 inches. A charge lasts up to 24 hours, so it goes on the charger each night. Premier Pet lists the collar as water-resistant, not waterproof, and backs it with a 1-year warranty.

Setup takes a few button presses and no phone at all. That suits an owner who wants nothing to install. But it also means you change the circle on the collar itself, so you’ll take it off your dog to adjust it.

### Pros

- $139.99 with no app or plan
- Setup happens on the collar
- No correction on the way back in

### Cons

- Circle only, set on the collar
- Dogs 20 lb and up

## 7. Invirox GPS Wireless Dog Fence

Invirox also sets its fence on the collar, with no app, no SIM card (the chip a phone uses for cell service) and no Wi-Fi. You pick a circle with the collar’s buttons. Its radius runs up to 999 yards in 99 steps, and the collar remembers it after a restart.

That circle shapes everything else. On a lot beside a road, a circle big enough for the back lawn can also cross the road. So the line has to shrink to the nearest edge, and a square lot with the house near the middle suits it best.

At the edge, the collar sounds a tone and vibrates, and you can add static. Each one has six levels, and you set them one by one. Invirox lists 1 to 2 yards of accuracy for its GPS chip.

A charge lasts up to 24 hours of steady use. It uses a magnetic USB charger, so the collar goes on it every night. The collar is IPX7, which means it can handle rain and a swim.

The strap fits necks from 7 to 22.5 inches. Invirox doesn’t list a minimum weight, so measure your dog’s neck before you order.

Invirox sells the fence for $139.99, down from $189.99. It comes with a 2-year warranty and a 30-day money-back guarantee. Its product page shows 5 verified reviews, so there’s little owner feedback to go on yet.

### Pros

- Low price for a GPS fence
- No app, plan or SIM
- 2-year warranty

### Cons

- Circle only, set with buttons
- Few owner reviews so far

## How to choose

Choose a GPS fence by checking five things in order: your yard size, the shape of your land, the plan, the phone, and your dog. I always start with the first one, because it rules out the most collars.

### 1. Is your yard big enough?

Plan on half an acre or more, because GPS drifts a few feet and the line needs room inside your property. PawTronic works on 0.5 to 200 acres. Dogtra and Premier Pet ask for 3/4 acre. On a smaller lot, a buried-wire fence follows the line more tightly. Check your yard.

### 2. Does the line follow the shape of your land?

A good GPS fence lets you draw your own shape, because few yards are circles. PawTronic gives you a circle or eight points on a map. That way, the line can bend around a driveway or run along a field edge.

### 3. Will you pay every month?

A required plan adds about $120 a year for each collar. PawTronic needs no plan of any kind, and its app is free. Halo’s fence stops working without a membership.

### 4. Does the fence work when your phone is inside?

The fence should live on the collar, not on your phone. PawTronic saves the boundary to the collar. So the fence keeps working while your phone charges or sits out of range.

### 5. Does the collar fit your dog?

Check the neck size and the alert modes first. PawTronic fits necks from 8 to 25 inches, and it can cue with a tone or a vibration, with no static needed. Dogtra and SpotOn start at 15 lb.

| What to check | Why it matters | PawTronic Pro Series 2 |
|---|---|---|
| Plan | A plan adds about $120 a year | None |
| Smallest yard | GPS needs room inside your line | 0.5 acre |
| Shape | Few yards are circles | Circle or 8-point shape |
| Works without your phone | Your phone won’t always be near | Yes, the map lives on the collar |
| Alert modes | Start gentle | Sound, vibration, both, optional static |
| Dog size | The collar has to fit | Neck 8 to 25 in, from 7.9 lb |
| Battery | A flat collar is no fence | Up to 36 h GPS standby |
| Water | Dogs find mud | IP67 |
| Returns | A safety net if it doesn’t fit | 30-day returns, 1-year warranty |

## Frequently asked questions

### What is the best GPS dog fence?

PawTronic Pro Series 2 is the best GPS dog fence, because it fits your real property line and never asks for a monthly plan. It covers half an acre to 200 acres with a circle or an 8-point shape, and it costs $278.99 once. The boundary lives on the collar, so the fence keeps working when your phone is inside. Read our PawTronic review

### What is a GPS dog fence?

A GPS dog fence is a collar that keeps your dog inside a boundary you draw on a map. The collar checks its position by satellite and cues your dog with a tone, a vibration or optional static at the edge. There’s no wire to bury. PawTronic Pro Series 2 works this way with no subscription.

### Does a GPS fence need a subscription?

Some do. Halo’s fence needs a membership from $9.99 a month per collar, and PetSafe Guardian GPS 2.0 needs a plan at $9.99 a month or $99 a year. PawTronic needs no subscription of any kind, and its app is free. Fences without a subscription

### What is the best GPS dog fence without a subscription?

PawTronic Pro Series 2 is the best pick with no subscription. It costs $278.99 once and draws a custom 8-point boundary from half an acre to 200 acres. SpotOn also skips the plan for fencing, but it costs $999.

### How much does a GPS dog fence cost?

Prices run from $139.99 for a circle-only collar to $999 for SpotOn, plus any plan. PawTronic costs $278.99 and nothing after that, because it has no plan. Halo costs $524 plus $9.99 a month on its monthly plan, which comes to $883.64 for one dog over three years.

### Do GPS dog fences actually work?

Yes, GPS fences work when the yard is big enough, the sky is open, and your dog learns the cue first. Drift of a few feet is normal, so the line needs room. Heavy trees and tall buildings can throw the collar off, which is why most makers set a minimum yard size.

### How accurate is the boundary?

The boundary is accurate to a few feet under open sky. GPS.gov puts typical phone GPS accuracy at about 16 feet in the open, and the makers list 3 to 15 feet of drift. Keep the line at least 25 feet from a road, the strictest setback any maker asks for.

### What is a GPS dog collar fence?

A GPS dog collar fence is the same thing as a GPS dog fence: the collar is the fence. It compares your dog’s satellite position with the boundary you saved. PawTronic’s collar stores up to six boundaries and works without your phone nearby.

### Is a wireless or GPS dog fence better?

GPS is better from half an acre up, because it follows any shape and needs no base unit. A radio wireless fence draws a circle around a base unit indoors, so it suits a small, square yard. PawTronic covers half an acre to 200 acres with a circle or an 8-point shape.

### Is GPS better than an invisible fence?

On half an acre or more, GPS is the easier choice for most owners. A buried-wire fence, often called an invisible fence, needs a trench around the whole yard and stays where you dug it. PawTronic needs no digging and follows any shape up to 200 acres. On a small lot, buried wire follows the line more tightly.

### Does a GPS fence need Wi-Fi or cell service?

Most GPS fences don’t, because the fence runs on satellites. PawTronic sets up over Bluetooth and stores the boundary on the collar. PetSafe Guardian GPS 2.0 needs 2.4 GHz Wi-Fi for setup. Live tracking on Halo, SpotOn and PetSafe needs cell service on a plan.

### Do GPS fences work in the woods?

GPS fences work under light tree cover, but dense canopy blocks satellites and makes the position wander. Keep the line in open ground where you can, and walk it with the collar in hand to hear where the tone starts. If your land is mostly thick woods, PawTronic’s team can check the fit before you order.

### What size yard do you need?

You need about half an acre, which is where PawTronic starts. GPS drifts by a few feet, so the line needs room inside your property. PawTronic covers half an acre to 200 acres. On a small suburban lot, a wired fence is the better tool. Will it fit your yard?

### Will a GPS fence work on one acre?

Yes, one acre sits well inside PawTronic’s range of half an acre to 200 acres. One owner in PawTronic’s reviews fenced a 1-acre property with the 8-point shape and needed two 10-minute training sessions.

### How far can the boundary go?

PawTronic’s circle reaches a radius of up to 7,000 feet, and its custom shape covers up to 200 acres. SpotOn lists more than 100,000 acres, for $999.

### Can you use a GPS fence on a small dog?

Yes, a GPS fence works on a small dog if the collar fits. PawTronic fits dogs from 7.9 lb with necks from 8 inches, and it can cue with a tone or a vibration alone. PawTronic asks owners of small or young dogs to stay on alert levels 1 and 2 and skip static.

### What age can a puppy start?

Wait until your puppy is over six months old and knows basic commands. PawTronic sets six months as its minimum, and PetSafe’s guide gives the same age. Start with the tone only, on a leash.

### Can a dog run through a GPS fence?

A dog can run through any electronic fence when it really wants to chase something. VCA Animal Hospitals notes that a dog may breach an electric fence for something it wants to chase or when it’s frightened. Training on the tone is what makes the line hold, so give it the full two weeks.

### Does a GPS fence keep other animals out?

No. The collar only cues the dog wearing the collar, so stray dogs and wildlife can still come into your yard. To keep animals out, you need a physical fence.

### How long does the battery last?

PawTronic lists up to 36 hours of GPS standby, and it recharges over USB-C in 2 to 3 hours. Charge it overnight, like your phone, so it starts every day full.

### Can one collar work for two dogs?

Yes, but each dog wears its own collar. PawTronic sells two- and three-collar packs that take $55.78 or $125.52 off. With a plan-based collar, each dog also needs its own plan.

### Is a GPS fence safe for dogs?

A GPS fence is safe when you train with rewards and start gentle. PawTronic can cue with a tone or a vibration alone, and static stays off unless you choose it. The American Veterinary Society of Animal Behavior recommends reward-based training, so start every dog on tone and treats. PawTronic’s manual limits wear to 12 hours a day.
