Reviewing the 10 Best Shock Collars for Large Dogs

We’ve gone through what makes a dog training shock collar suitable. The critical part is making sure that you know which ones to buy. There are many options to choose from, and there isn’t any specific “best shock collar” that’s better than the rest.

Each has its bonuses and flaws, which are all essential to consider. That said, continue reading to go through our list of reviews for the best dog shock collars for large dogs out there.

We’ve listed every one of the best options, along with their most prominent advantages and disadvantages.

1. Pet Resolve PTS1200 (Editor’s Choice)

What is versatility?

I would say Pet Resolve. It’s simply the Swiss Army Knife of dog training shock collars… 

I’ve laid my hands on a variety of dog training collars, and none are both versatile and effective as this one; it just gets everything it’s supposed to SPOT ON. 

Pet Resolve might be the BEST thing you’ll be doing for your dog. This shock collar, most importantly, fits any dog over 15 lbs, which slots right in the large dogs category.

Zero worries if you own a Hulking German Shepherd or a Mammouthus Maximus Great Dane, Pet Resolve will WORK!

That said, here’s why I think Pet Resolve is a Jack of all trades.

Firstly, let’s get through the essentials. This shock collar isn’t just a shock collar; you get a vibration feedback along with beep. You don’t need to use shock to get your dog’s attention all the time. 

For example, if your dog has understood the basis of training with shock and is now obeying your commands much better than before, you can resort to vibration or beep. One of the two will, no doubt, get the job done from there on in. 

RULE Number one: It’s important to get a collar with additional feedback options

With the added feedback options, Pet Resolve’s shock and vibration mode, on the other hand, is adjustable; there are 10 levels of continuous or momentary levels. Based on your dog’s behavior and temperament, you can pick one that works. 

Most collars don’t have this, and the outcome?

An alarmingly powerful shock that can cause a whole lot of pain; you’ll have no idea! 

Being able to adjust the intensity of the shock is a great benefit, and Pet Resolve excels in that. 

Not just that though. The stability of the connection between the transmitter and the collar (range) is another area where Pet Resolve Nails it. You can correct the dog from as far as 3/4 Mile (3936 feet).

That is the HIGHEST RANGE of any dog-training shock collar on this list, super high, to the point where you can even use it while hunting with your dog. 

That’s all the essentials covered; looking at everything, there’s simply no other collar that does it better than Pet Resolve. 

Now let’s take a look at some of the features that set Pet Resolve clear of its competition. First, the ability to control a max of three dogs at once. If you’re a parent of up to three dogs and want to train all of them at once, you can do that with Pet Resolve, purchase extra collars, and you’ll be all set. 

Second, You can use Pet Resolve as an anti-bark collar too. Pet Resolve will detect whenever your dog bark on its own and will correct it with the mode chosen; you don’t have to manually correct your dog for unnecessary barking. That is an option that no other shock collar in the market provides.

Third and probably one of the most important. The collar is completely waterproof; no need to worry when it comes to contact with water. 

I could go on and on, as mentioned earlier, Pet Resolve is, without a doubt, a do-it-all dog-training shock collar. It deserves the top spot more than any other collar on the market. It’s that good.

Shock Collars and Their Functioning

Training a Dog with Shock Collar

Most people are already familiar with what dog shock collars are. You can use a training collar to train your dog and correct his behavior. But, it’s also essential to know how this works.

As it’s a type of dog training collar, you’re the one that’s going to be in control of it. That means you’re responsible for the inputs and ensuring that you time corrections right. 

There’s a receiver on the collar and a transmitter which is the remote that dog owners hold. You can communicate with the collar and correct your dog’s behavior through this remote.

The two components communicate with each other through signals. How far these signals travel depends on the specific types of collar you’re using. So, now that we know a bit more about how the device works, let’s get down to the basics of purchasing one.

Key Factors to Address Before Buying a Shock Collar

When buying the best dog collars for large dogs, you can’t just choose the first option that suits you best. When you buy things for yourself, you always spend time getting the very best, isn’t that right? 

Well, the same should be done when getting your dog a training collar. But, buying the best dog shock collar is much easier said than done. There are many factors to consider, especially when purchasing a shock collar for large dogs.

Best shock collars for large dogs

Here’s a brief rundown on what these factors are and why they’re so important before buying a shock collar for large dogs:

Variety in Training Modes

It’s essential to remember that the best dog training collars will always offer lots of variety in training modes and intensity levels. This specific factor is crucial because medium and large dogs are stronger than small dogs.

A specific training mode might not work on them, which is why you need a few. That way, you can test all the different options out and see which one works best on your pup.

Most modern shock collars also have levels to each mode. That way, you can adjust the intensity of the static shock. This makes it easier to find an ideal level for training your dog while also ensuring that the corrections don’t hurt him.

Durability and Design

This next factor speaks for itself. A dog training shock collar is put to the test daily. If it’s not durable, it’ll break easily. There’s no point in getting a device like this because it’s a massive waste of money.

That’s why the best dog shock collars are always built to last. That way, they can withstand regular use for months or even years at a time, letting you get your money’s worth.

But that’s not all that’s important. You also have to make sure it’s got a good design. If a collar has an awkward design, it’ll likely make your dog feel uncomfortable. No dog owners want that for their dogs, so you must look for comfy options.


An electric shock collar should always be easy to use because otherwise, it’s a chore for both you and your dog to work with it. So always look for effective and convenient options in most ways.

For example, the button layout should be easy to understand and simple to work with. The collar should also have a decent range so that you don’t always have to run after your dog to make it work. 

Some of the best large dog collars also include standby modes and security locks.

Last but not least, always remember to get an electric dog collar that has good battery life. If your dog training collar keeps dying on you whenever you go out to use it, it’s not useful for much, is it?

It’s up to you to ensure you get a rechargeable dog shock collar that can last for a long time. Your e-collar should always be reliable in this aspect so that nothing goes wrong during a training session.

How to Use a Shock Collar on Large Dogs?

A large dog breed wearing a shock collar

Using one of these devices is much more than pushing a single button and hoping it makes your pup behave better. It’s a complicated and lengthy process that is different from usual when working with large dogs.

That’s because the bigger guys are always stronger and more stubborn. They’ll take each correction like a champ and do whatever it is they’re doing all over again. You need to know what to say to prevent this from happening.

If you learn the correct commands, it’s possible to teach your dogs all kinds of things with a dog training collar. (1)

That said, here are some of the things you should focus on teaching the big guy once you’ve purchased an e-collar and want to start training with it:

  • You should teach him basic commands like sit, stand, wait, follow, and more if he already knows them. These are some of the simplest things that all dogs should know.
  • Stop his excessive barking. Most large dogs tend to be very loud. Electric shock collars are a great way to deal with this. Put the device on him and correct his behavior whenever the big guy barks too much. (2)
  • Teaching him how to walk and off-leash training is also essential. You can teach the doggo these by exclaiming “NO” and triggering the device whenever he gets too far away from you. Eventually, he’ll stay by your side on his own.
  • Train him not to make messes. Big dogs can sometimes leave large messes behind. Whenever your dog does so, make sure to reprimand him through words and the collar itself. He’ll know not to make messes again after you repeat this a few times.
  • Most dogs love to jump at people, which is a habit you should get rid of. Whenever you’re expecting guests, make your pet dog wear his shock collar so you can correct him whenever he jumps at someone.

Yes, shock collars can work on big dogs, but their effectiveness may be diminished due to the size of the dog and its fur.

The PetSafe Basic Bark Control Collar is the safest shock collar for a dog, as it uses a static correction to stop barking, which is safe and effective for most dogs.

The use of shock collars is a matter of opinion, and there is no universal answer. Some vets may recommend them as a training tool, while others may advise against them. Ultimately, the pet owner decides to make in consultation with their veterinarian.
