The 6 Best Underground Dog Fences

1. PetSafe Basic In-Ground Fence System – Best Overall

At the top spot for our list of best underground dog fences, we have the PetSafe Basic In-Ground Fence System. As far as underground fences go, it's a simple setup that'll allow you to have it up and running within a weekend.

PetSafe's system comes with a boundary wire that can encapsulate ⅓ of an acre; however, you can purchase an additional boundary wire to extend the range to 5 acres! The fence is rated for dogs that are 8 pounds and heavier with collars that will fit necks between 6 and 28 inches.

One of the biggest advantages of this system is the capacity for multiple dogs—and at multiple sizes. And that's possible because the static setting is adjustable from the individual collar. That means you can up the shock on larger dogs, but dial it down for smaller pups.

And speaking of the "shock", it's not a painful zap. Instead, it's more of a gentle static correction that will surprise and train your pup into staying within their flagged boundaries. The PetSafe fence comes with 50 individual flags, that way your pup can easily see where they should and should not be.

All-in-all, the PetSafe Basic In-Ground System is an excellent overall choice for keeping your pet safe.

2. HoistSpark In-Ground Dog Fence System – Best Value

The HoistSpark In-Ground Dog Fence System is a budget-friendly alternative in-ground fence, and it comes with two rechargeable waterproof collar receivers in the box. The 500 feet of included boundary wire covers approximately a third of an acre and can be expanded up to 40 acres with additional compatible wire purchased separately. The collars offer tone, vibration, and multiple levels of static stimulation, allowing you to tailor the correction to your dog's temperament and start at the lowest effective level before increasing if needed.

Setup is straightforward according to most Chewy reviewers, who note the included step-by-step instructions are clear enough to complete installation in a few hours without professional help. One important limitation to flag before purchasing: additional replacement collars are not currently sold separately by HoistSpark. The system can also be sensitive to nearby electrical wiring in some home configurations, which may require the correction level to be set lower than expected. For a two-dog household on a budget that wants rechargeable collars and a solid coverage area out of the box, we think this is the best underground dog fence for the money this year.

3. SportDOG Brand In-Ground Fence – Premium Choice

If you're looking for the Rolls Royce of underground dog fences, this is it. The SportDOG In-Ground fence is without a doubt the premium choice. For starters, it comes standard with a 1⅓ acreage coverage that's extendable up to 100 acres! But the extensive coverage isn't the only thing that this fence has going for it.

The dog collar itself is powered via a single 9V battery and can last up to one year without replacement. It fits dogs from 10 pounds and up and has 4 different levels of correction so even the most stubborn of dogs can receive the message. But before the collar delivers the static, the device gives your pup 2 separate warning signs: a tonal sound and vibration.

Another extraordinary feature that the SportDOG has is a break-in line alarm. This will inform you if there is an issue with the fence and if it's not working properly. The SportDOG also has lightning protection, so one errant bolt won't take down your whole system.

The biggest issue with this fence is that to get all these premium features, you've got to pay premium prices.

4. PetSafe Stay & Play Wireless Dog Fence for Stubborn Dogs

The PetSafe Stay & Play Wireless Dog Fence for Stubborn Dogs is designed specifically for dogs that are difficult to contain and require a higher level of correction to respect a boundary. The wireless transmitter sits indoors and creates a circular containment area up to 3/4 acre in diameter without a single wire to bury or lay — setup takes around one to two hours and requires nothing more than positioning the transmitter and walking the boundary with your dog during training. The collar receiver is waterproof and rechargeable, with five levels of static correction and a tone-only mode for less sensitive dogs.

For flat, open yards where a circular boundary suits the property shape, and for owners who want to avoid digging or burying wire entirely, it is the most convenient containment option available without any ground work required.

5. SportDOG Brand In-Ground Dog Fence System

The SportDOG In-Ground Dog Fence System is a proven, field-tested containment solution built to the demanding standards SportDOG applies to all of its equipment for sporting and working dogs. It comes with 1,000 feet of boundary wire and 100 training flags, covering 1 1/3 acres out of the box and expandable to 100 acres with additional wire and flags purchased separately. The transmitter includes a wire-break alarm and built-in lightning protector, and the collar is waterproof and robust enough to hold up to daily outdoor use in any weather.

SportDOG builds its containment systems for sporting dogs and working dogs — breeds that are fast, driven, and accustomed to testing limits — which means the system performs reliably even with high-energy, stubborn, or determined dogs. Four correction levels give you enough range to tailor the boundary response to your dog's temperament, starting at the lowest effective setting and increasing only as needed. For reliability, coverage, and the peace of mind of a battery you can replace anywhere without waiting for a charging cycle, it is a dependable and no-nonsense in-ground fence system.

6. Dogtra E-Fence 3500 Underground Electric Fence

Last on our list is the Dogtra E-Fence 3500, but that doesn't mean it's a terrible option. It's on our list for a reason. It's a top-notch fence! The EF-3500 can cover 40 acres straight out of the box which more than covers the space needed for any dog.

However, our favorite features that this fence system has are its quality control features. It has a break-in line alert that will let you know if there's an issue with the fence and continuity. It also comes with an electric signal filtering device to prevent any outside electrical interference. You can even purchase special surge protectors separately that will protect your control box from unexpected electrical spikes.

We also appreciate the dual warning system the fence has before direct stimulation. Both a warning buzz and audible alarm will indicate to your pup that they're approaching their boundaries. Another thing we love about this system is that the collars are very well crafted. They're IPX9K rated to keep them waterproof and airtight.

However, we wish the collars could accommodate larger dogs. They work great for leaner pups, but there'd be an issue strapping them onto a St. Bernard. Also, they need to work on the battery life of the collar. It just doesn't last long enough.

Buyer's Guide - How to Choose the Best Underground Dog Fence

Finding the best underground dog fence for you is more than just reading a quality review. Our top pick might not be the best system for you. To determine which is the right underground fence for your pup, you need to examine several different criteria.

Land Area

The first thing you should consider is when purchasing an underground dog fence is knowing how much land area you're trying to fence in. If you need to wrangle in 5 acres of land, purchasing a fence system with only a half-acre isn't going to cut it.

But it works both ways as well. You don't need to go out and buy a huge fence system if you don't have space. The problem with this is the installation. Doubling back extra wire or cabling can be very difficult and may cause breaks in the line.

So, before you commit to anyone's fence, be sure to properly measure your land space.

Levels of Stimulation

When selecting your new dog fence, the provided level of stimulation is extremely important. It's a very fine line that you'll have to walk. Too low stimulation and the fence won't be effective. Too high, and you may end up doing harm to your dog or scaring them completely.

The best solution to this is finding a fence with multiple levels of static stimulation. And the more levels available, the easier you can dial in the exact right amount.

Size of Your Dog

The size of your dog is an extremely important factor. You may notice that when shopping for underground dog fences you'll see size restriction disclaimers. There may be a minimum size that is needed to even use the collar in the first place. Normally, toy-sized dogs and other small pups can't use stimulation collars.

If you have a large-sized dog, there are other problems you'll encounter. The system's collar might not even fit around your pooch's neck, which renders the system useless. Or, the fence system might not be able to put out enough stimulation to be an effective deterrent and training device.

Battery Considerations

The collars that come with each underground fence system are battery operated. But those batteries come in different variations. Most collars these days come with rechargeable batteries. These are great for efficiency and much cheaper in the long run. However, they're not going to last as long on a single charge.

Traditional battery-powered collars tend to last much longer than their rechargeable counterparts. However, the cost of changing out those batteries can quickly add up—especially if you have more than one dog.

Number of Dogs

It's very important to think about how many dogs—more specifically dog collars—will be taking up load on the system. Some systems are only designed for a limited amount of dogs. Fortunately, each of the systems on our list can serve an unlimited number. However, each dog will need to have their very own collar. And that's going to cost extra as most systems only come with a single collar.

Waterproof Collars

Water and electronic devices don't normally make for a very happy relationship. That's why your dog's collar must be completely waterproofed. If a collar isn't waterproof and gets wet, it may not work at all. Or even worse, the collar may send random stimulation at improper times.

Type of Correction and Alarms

Not all underground fence systems have the same stimulated correction. However, you shouldn't look for a traditional shock collar. Instead, you want to find a system that releases a gentle stimulation that won't cause any harm to your pup.

Also, many fences have other means of alerting your dog before delivering static stimulation. An audible alarm or quick vibration are common approaches with underground dog fences.

Price

Perhaps, one of the very first things you'll look at is the price. Underground dog fences aren't cheap. Even the most cost-efficient fence is still going to cost a pretty penny. So when shopping for a new fence, be sure to stay within your allotted budget.
