Top 6 Radius Shock Collars for Dogs 

1. Halo 2+ (Editor’s Choice)

There’s no better way to start off this list other than with Halo shock collar, hands down the best radius collar for dogs.

It’s a dog training device, wireless fence system and real time GPS tracking system.

Isn’t that itself enough to secure the top spot?

There are similar collars on the market, but they never seem to be as effective as the Halo 2+, it does everything it claims just better than all else. 

First, let me tell you about the size, It can easily fit any dog that has a neck size of 11 in. to 30.5 in.

That means any medium to large dogs will fit into the collar without any problems.

However, it would be better if you measure your dog’s neck before getting one. 

Being the best radius collar, it’s important to have a good range, and Halo, in that regard is more than good, YES, from what I’ve seen, there’s nothing better. 

Halo offers a maximum range of 6.2 miles, that is adjustable to be as small as 30 feet. Adjustable range in a collar of this type is a rare site, it’s great to see that in this one.

However, to achieve that wide 6.2 miles of range, you need to create fences.

Halo itself lets you create 20 virtual fences anywhere you like and each of those 20 can be as big as 6.2 miles with any shape. And inside each fence, you can also train your dog. 

That’s even excellent. 

For training, there’s a boat load of features that you can take advantage of. For starters, it has four training modes; Tone, Voice, Vibration and Static Feedback.

With that, there’s even 15 adjustable intensity levels for static stimulation, you can adjust the level based on the temperament and behavior of your dog. 

That also provides excellent versatility during training, 15 intensity levels along with an already impressive set of training modes and mighty range. 

That’s everything you’ll probably ever need to train your dog, it’s simply perfect. Halo 2+, as mentioned above, is also a wireless dog fence system. That is what it’s actually marketed as.

You might already know about virtual fence systems, it can help you to contain your dog and stop it from straying all together. 

A dog training collar with a virtual fence, isn’t it great? But wait, there’s more, didn’t I tell you that this is a GPS tracking system too. With Halo 2+, you can keep an eye on your dog 24/7 even when you’re nowhere near it. 

How? If that’s your question, here’s the answer

Just download the Halo app on your mobile phone, sync your collar and you’ll be all set. And by the way, the app is not only there to check your dog’s location, it is what you’re going to use to control the whole system.

Unlike other radius collars, Halo does not come with a remote control (transmitter), instead everything from creating fences, training dogs, checking the dog’s location is done through the app. 

It’s actually great that it does not come with a remote, these typically tend to be bulky and large and carrying them everywhere you go with your dog isn’t going to be fun. 

All of these are just a peak of everything Halo 2+ is capable of offering as a radius collar, there’s much more to it than this though. However, these itself cements its position as the best radius collar money can buy.

How Does a Radius Shock Collar Work?

Radius shock collars work by giving a small electric shock to your dog through metal contact points in the collar. The receiver collar that the dog wears communicates with the remote transmitter in your hand. 

E-collars have different training modes and shock intensities to grab your dog’s attention. Beep, vibration, and shock are the training modes found in most collars. It’s up to you to choose the best setting that works for your dog.

Are E-Collars Safe?

Yes, if you follow the instructions and stick with the lowest effective shock levels, they are perfectly safe. Remember to start with beep and vibration and use shocks only in extreme cases.

The shock administered is enough to get your dog’s attention without doing him physical harm.

To make sure that your pup is safe and comfortable:

What Are the Benefits of Using a Radius Shock Collar?

Gives more freedom to your pup: If you are using a radius shock collar, you can give your dog the freedom to walk without a leash. 

Keeps your dog safe: Yes, a dog training collar can protect your dog if properly used. For example, if your pup loves to run away, training with a shock collar will keep him safe within your property boundary.

You can fix unwanted behavior from a distance: A shock collar is an excellent way to correct off-leash behaviors like digging and running away. Also, with a shock collar, you can command your dog from a distance without yelling.

Makes your dog more obedient: Dog shock collars are guaranteed to make your pup obedient, given that you train him regularly and with a lot of positive reinforcement.

Quick results: If you’ve tried training your dog for years to no avail, e-collars can give miracle results. Most pups only need a single shock to realize they are doing something wrong. After a couple of days, the vibration mode is all you need to correct your dog’s behavior.

Easy to train many dogs simultaneously: Most dog training systems are expandable, and you can train 2, 3, and sometimes more dogs simultaneously. This is a significant benefit if you own many dogs.

Affordable: Yes, shock collars are very affordable. Much cheaper than training dogs from professional classes. If you are ready to spend some quality training time with your dog, a dog shock collar is your best bet.

What are the Key Features of an E-Collar?

Different dog training collars come with additional features.

Whatever dog shock collar you pick, these are the essential features of an e-collar.

Range: Range is super important. Collars with a short-range work well on indoor and backyard training. But if you want to train your dog on long-distance walks and off-leash, always go for a long-range training collar.

Levels of shock/vibration: Some collars have up to 10 levels of shock, while other collars have 1-99 levels of shock. If you are unsure of the best shock level for your dogs, go for a collar with more intensities.

Security keypad lock: This is a helpful safety feature to protect your dog from getting shocked by accident. If your training remote comes with a security switch, you can safely carry it in your pocket without worrying about shocking your dog.

Night light: Some e-collars come with a built-in LED light in the shock collar. The night light is a necessary feature for dog owners that let their pets out at night. The night light also comes in handy in low visibility conditions like fog.

How to Start Training With a Radius Shock Collar?

Set up the shock collar: You will receive contact probes to attach to the collar receiver. Usually, there will be a longer set of probes for long-haired dogs and a shorter set of probes for short-haired dogs. Go through the user manual and follow the instructions carefully to set up the collar.

Test the shock collar to make sure it’s working correctly: The easiest way to check is to use the test light tool. When you hold this to the contact probe, it will light up.

Fit the collar: A good fit is crucial for the shock collar to work. A rule of thumb is to check if there is enough space to slip two fingers between the shock collar and your dog’s neck. Also, ensure that the collar receiver is at the base of your dog’s neck.

Start training! : Always start with a low-intensity setting and work your way up until you get a response from your dog. Teach your dog basic obedience commands like “stop” and “stay” before starting shock collar training. Your dog must learn to associate your orders with his behavior. This way, he will learn to obey you even without an e-collar.


No, e-collars do not need Wi-Fi to work. However, some brands offer Wi-Fi-enabled shock collar technology, which allows owners to track their dog.

The average range of an e-collar is usually between 1500-2000 ft, but the actual range can be lower if there are obstacles in the way. It is recommended to purchase an e-collar with a range that is greater than what is needed to ensure maximum coverage.

Radius shock collars use electric shocks to deter dogs from crossing a boundary line by sending a mild shock for a few seconds when the dog gets too close to the line.

Halo 2+ is undoubtedly the king when it comes to range with 6.2 miles.


Now’s the time to pick the best collar for your dog. The right shock collar can give you a rewarding training session that you and your pet can enjoy.

For me Halo is the right pick, you saw it yourself, the amount of options it gives you during training along with other features deservedly puts it in the top of the line. You simply can’t ask for more. 

Pet Resolve Dog Training Collar on the other hand is another great choice. With a 3960 ft range, this collar has one of the best range among our top picks! Pet Resolve is also the only collar with anti-bark function. For its price, it surely is something that you can consider. 

So choose your favorite dog training collar and begin training. With positive, regular training sessions, your dog will be an obedient pet in no time.
