Every dog is different. That’s something I learned from my 12 years of strenuous dog training. Some breeds listen to you right on the first cue but some have a nonexistent recall and I call them Stubborn.

It is the latter ones that need shock collar intervention. With breeds like Mastiffs, German Shepherds, Siberian Huskies, and so on, you cannot miss your chance to correct their behavior. They need strong collars.

Strong shock collars have high levels of static shock levels accompanied by vibration and beep features. They transmit a consistent and considerable shock to the dog’s neck to stop them in their tracks. Such powerful stimulations are sometimes needed for stubborn dogs with an independent streak to make them listen to you. You should know that they are not powerful enough to electrocute the dog. And that you should learn to use them humanely to avoid any injury.

Here’s my recommendation for the strongest shock collars for dogs you could find. 

These collars have been picked after great consideration. However, know that the way you use them has a greater hand in the results they give.

Please do not use the collars for punishment and only use them when you’ve learned how to.

When And Why Do You Need a Strong Shock Collar for Your Dogs?

I don’t recommend a strong collar for every other dog. My number one reason is that it could hurt the poor soul without knowing at all. 

Not because the collar has something against your dog or you’re not a good parent, but because the intensity of stimulations just doesn’t meet the dog’s requirements. It may be stubborn or single-minded but should you still use one of the strongest collars on him given on the list?

Let’s find out.

1.  Breed

Breed plays the number one role in deciding if a dog needs a strong collar or not. Owning a Mastiff is a different ball game than owning a miniature poodle. The difference is obviously in their sizes and their capacity to take sudden hot shocks.

That inevitably takes the small breeds out of the equation because they simply aren’t built to take that much.

2. Stubbornness

Now stubbornness is the single big motivator for dog owners to use collars with significant stimulations. But underneath that stubbornness, there’s always a reason that may not ask for a big collar at all. 

One of them is the lack of attention or too much attention. In breeds such as Rottweilers, too much attention could cause stubbornness as they try to overpower you for the Alpha seat. They may lie in your doorway and try to make you go around them.

Secondly, there are breeds that are naturally stubborn such as Huskies. They are single-minded and know how to get away with anything as they escape artists.

When you find the reason for their stubbornness and figure out a way to reduce it, using strong collars wouldn’t be required.

However, if you want to take a shortcut and do that by all means when things have taken an unwanted course, then using them is necessary. 

3. Aggression

This is another reason why using collars with strong static stimulations may become indispensable. Aggression isn’t just a one-breed thing. Even the smallest breeds with seemingly no previous such history may get aggressive for a number of reasons. 

I’ve seen dogs such as Pugs and those bat-ear cuties French Bulldogs get out of their owners’ hands because they are either abused, punished ruthlessly, or their illnesses are ignored altogether. 

With an aggressive dog, therefore, there’s at least some history of mismanagement that needs to be taken into account.

There are training regimes to help a dog with its aggression, but the use of strong shock collars may come in handy when the dog has the tendency to hurt someone.

4. Unwanted Behaviors

Some unwanted behaviors such as jumping on people, ripping furniture apart, chasing children and small animals, and running away into the wild warrant invention with a shock collar.

The reasons are obvious. You don’t want the dog to hurt someone or to see it get hurt somehow.

Jumping on you or guests, for example, could ruin their clothes or scare them away; chasing children ends up in them tripping and falling and small animals may get eaten or wounded; running away will put the dog’s life in danger as the traffic on the road may become cruel.

In such situations where there’s an imminent threat and you can’t spend days on end to correct them, shock collars play a huge role. They will not only teach the dogs to stop these behaviors but also tone down their excitement in other places.

What are the Strongest Dog training Collars?

Here’s a list that you may find worthy!

1. Pet Resolve

Buttons Instead of A Rheostat

What’s better than a rheostat dial on a remote? Buttons of course. That’s one of the reasons why I recommend this collar to novices.

It’s super easy to get to the desired function without needing to learn complex pathways. That doesn’t mean you shouldn’t read the manual though.


About the strength of the stimulation, this isn’t a level 1 to 100 collar. It only has 10 levels but oh boy, they are hot.

If I were to give you an objective comparison, level one of the collar could be equal to level 3 on a mid-range shock collar. 

Therefore, before using it on your dog, do check it on yourself. I remember training a 60lbs Doberman for whom level 4 did the job.

Level 5 was enough to stop a mastiff of 150 lbs in his walk and come back at the owner. But this was too much for a 1-year-old Pitbull who was an escape master. 

The reason why I’m telling you all is that every dog responds differently to the collar but one thing is for sure, dogs with high shock resistance stand no chance against this one. 

LED On The Collar

Plus at its price, the collar gives a lot of things – some you may not have even asked for. There’s an LED in the collar for night walks, a test light, a dual-mode charger, prongs for long and short coats, and so on. 

You don’t have to use the shock feature if you don’t want to. That could be the case when the dog has successfully been corrected.

Use the plastic covers with the probs and you shouldn’t zap the dog even if you press the button accidentally.

There’s a stand-by mode but I wouldn’t want you to rely on it. The remote takes about 3 to 4 seconds before it’s functional after the standby mode. 

The company needs to correct that and also try to improve the quality of the remote.

Why Do I Recommend This Product?

They’ve outdone themselves in terms of features and charging that lasts for two days at most (better at this price) but I want to rely on the quality for future use.

What Makes It Stand Out?

It’s convenience wrapped in a workable design.


  • Separate buttons for each function
  • Easy channel switch
  • Hot shock levels for strong dogs
  • Excellent after service


  • All made of plastic
  • The collar’s charge doesn’t last longer than the remote’s


PATPET is my go-to collar when I’m training a peculiarly stubborn dog or a puppy. Yes, the collar works as well for pups as adult dogs.


I found its 16 levels of stimulation quite hot. There was one situation though when I had to go up to level 5 to get a Golden Retriever to listen to my commands. Other than that, I didn’t have to go beyond level 3. 

The fact that the remote works even from behind a wall takes this product up to the first slot on this list. That helped me a great deal when I was called to train a Great Dane from a distance.

Poor thing didn’t know from where that stimulation came but I’m sure he was aware of the heavens watching over his moves. 

Blind Usage

Training the owner was a part of the whole session and she wanted to use the remote blindly when she was in the kitchen or anywhere else. This one was an easy pick for that matter.

The indications, although not too visible, were easily found.

There’s a keypad lock in the remote but I wish it was a slide button. You’ll have to do it with a press-and-hold button that works in 1.5 seconds. 

Also, the remote isn’t waterproof. That we worked categorically because the owner’s hands were always wet one way or another on her farm. 


Design-wise, the collar could have been a great addition to the family of training methods you could use on your dog, but the location of the power on and off button under it doesn’t help much.

Your dog’s activities may turn it off accidentally. That’s only a guess. A maybe. 

Why Do I Recommend The Product?

I’ve no qualms about accepting that the product will correct your pooch’s behavior in no time. 

What Makes The Product Stand Out?

Patpet receivers are small enough for small dogs and thus, comfortable.


  • Quality product of a quality brand
  • Blind operation
  • Longer range
  • Works beyond the wall
  • Hot stimulation levels


  • The Remote isn’t waterproof
  • The keypad turn off button isn’t convenient

3. Dogtra 1900S Shock Collar

The Dogtra 1900S has everything you could ask for in a strong collar. Maybe that’s why it’s expensive. But for those who have tried everything on their stubborn dog in vain, this one could answer your prayers.

Strong Stimulations

It did answer mine when I had to train a Pitbull with high shock resistance. He didn’t budge even at level 16 of some collars let alone softer training methods.

One week into the use of this collar at a staggering level of 27 of stimulation and we got his attention. 

Yes, the shock was high but so was his bearing capacity. He had a yearning for breaking away from the leash and the fence or anything that held him back.

I also used continuous shock on the same dog when even that level of shock couldn’t break him. There’s even a high-performance pager as they dub it. 

High Performance Pager

A rebellious Dobe was contained successfully just by the HPP. Of course, we had to use it as a warning sign to warn the dog about what was next – level 25 shock.

So, you see that the collar has more than one correction method up its sleeve. If the shock doesn’t work, increase it. There are 127 levels.

If that doesn’t work, press the continuous shock button. If that doesn’t do anything, use the HPP. Or use all these interchangeably. 

That’s why I don’t recommend the collar for a smaller dog. Anything below 60 lbs shouldn’t get this treatment. Instead, you should see the underlying reasons for his rogue nature. 

Bulky Receiver

I also wish the receiver was less bulky. Although I had no problem using it with bigger dogs, and the fact remains that it’s built ergonomically, I still want it to be a little smaller.

Sometimes the dogs would notice its presence and be irritated just by wearing it. 

Why Do I Recommend The Product?

I recommend it for stubborn dogs who have a mind of their own.

What Makes It Stand Out?

The product will surely outlast many shock collars you have tried.

Shock Collar for Large Dogs


  • The strongest premium collar
  • 127 levels of stimulation even for the most stubborn dog
  • Built to last with a rubberized material for excellent grip
  • HPP adds a new layer to corrections


  • Expensive
  • You’ve to learn to use it first

4. ABBIDOT Training Collar

What better than getting a shock collar at an affordable price? The Abbidot is just that. 


It has 16 levels of shock, which makes it one of the hottest choices. The levels are consistent. You won’t experience an abrupt jump from level one to another when you check it on your arm.

I do recommend doing that just to be sure that you’re not zapping the dog too hard. 

Two Channel Support

There are 2 channels of support, which means you could train two dogs together. My time with a 9-month-old Doberman and a 4-month-old German Shepherd had been made easier.

The switch is pretty easy. I only wish that there was an option to select the individual shock levels of each dog. 

But the fact remains that you could use the collar for a variety of different dogs of different neck sizes. It’s even suitable for puppies, only if it’s been abused. 

The Shepherd I talked about had a dark past, too. His owner had been abusive, so it was a rescued dog in its new home.

He tended to crawl and then run away like there was some tape running in his mind. Poor thing. Gladly, we saved him from a fate of doom by using level 4 shock. 

Long Battery

Charging wasn’t a problem, either. I had stayed with that dog for over two months because he was a great work in progress. During that time, we had to charge the collar every 16 to 18 hours. 

The design of the remote and the collar are great, too. Only a single feature is missing from the remote, else I’d have called the product perfect. There’s no keypad lock button.

You’d have to turn off the remote to keep from accidentally zapping your pooch. That’s a bit inconvenient when you’ve to use the correction in an emergency.

Why Do I Recommend The Collar?

It gives you the features of a premium collar at an affordable price.

What Makes It Stand Out?

Each stimulation button has a different color LED.


  • Smart, lightweight design 
  • A lot of strap for any sized dog 
  • Consistent shock levels 
  • Works behind barriers 


  • No keypad lock button

5. PATPET Collar

The brand makes collars for a variety of dog types. Stubborn dogs that don’t listen well do listen to their collars. This one is one of them. 


I love how sleek and modern the design is. The company hasn’t shunned convenience in hopes of making it more appealing. The remote is every bit convenient with its few buttons on the front. 

First, I like the channel switch button, which isn’t a knob, thankfully. Then each feature button has indications on its top. You could use the remote blindly. I must warn you though that the beep and shock have the same indications.

That might confuse you. So, before using it blindly, make sure you’ve learned or memorized the scheme well. 


The collar has 16 levels of stimulation. Many dogs that I’ve trained with start responding at about 4 to 5 levels. I’ve only gone up to level 7 with an 8-month Husky with a long coat.

He was living in a clearing near deer and squirrels. The moment he sees them, a devil would awaken in him. His howling would become unbearable. 

We tried many shocks or bark collars on him but to no use. Some of them would go off when a nearby dog would bark. This collar saved the owner a great deal and I was relieved that the dog’s behavior was corrected.

Had he gone into the woods after the deers, the situation would have been different. 

Not just the shock, even the vibration is stronger and the beep louder than the other collars. 

No Battery Indicator On The Collar

My only complaint here is that there’s no battery indicator on the collar. You could get an idea of the remote battery from the indicator blinking on the screen but no such facility on the collar itself.

Make sure that you put it in charge after every 4 to 5 hours just to be sure that you don’t lose control of the dog.

Why Do I Recommend The Product?

The remote’s design is meant for novice users.

What Makes The Product Stand Out Among Others?

The collar is ergonomic. It follows the curve of the dog’s neck.


  • Better quality overall 
  • Sleek design 
  • Easy to use remote control 
  • Louder beep and vibration 


  • The collar does not last longer than the remote 

6. Bousnic e Collars

Brains and Beauty

The Bousnic E-Collar has brains and beauty. The sleek remote does not betray its well-rounded up functions. It is every bit of a shock collar with hot levels of stimulation. 

I do not recommend this for small dogs, although the strap is big enough to accommodate necks of varying sizes. Why I don’t recommend it for small dogs is because I had a bad experience with a Pomeranian. 

I know, I know. Who uses a collar on such a small pooch? Trust me, behind those googly eyes, we had found the devil looking back at us.

He was relentless, always barking at other dogs, biting and nipping at his owner, and not even caring about other training techniques.

He had been abandoned by his mother when he was a pup, so that didn’t rub well with his personality. 

I had to eventually switch to the vibration only. That worked like a charm. I found out that the vibration was stronger than most of the e-collars because it not only worked on this small dog but also tamed a Great Dane. 

Of course, I had to zap that giant with a level 4 shock to stop him from running after cars. That was for her safety. 

Easily Train Two Dogs With One

Training two dogs with the remote is a breeze with its dedicated channel switch button to the side. There’s no complication or extra feature given on the remote to confuse you.

Three buttons gawk at you with their indications etched out on them under a big-for-its-size LCD.

The collar, too, doesn’t seem to have a lot of shortcomings. It’s well-built. The nylon strap is exceptional and the receiver isn’t too big. However, the company needs to work on improving the battery life of the collar. 

Why Do I Recommend The Collar?

The remote has a beautiful convenient design and the receiver size is appropriate for all breeds.

What Makes It Stand Out?

You’ll love its bigger LCD.


  • Easy to use remote 
  • Built quality is better
  • Comes with two collars 
  • Shock levels are hot 
  • Vibration is stronger than other brands 


  • Collars’ battery life needs to be improved

7. Lu&Ba Shock Collar

Common Grounds With Bousnic

Lu&Ba and Bousnic have a lot of features in common. Their remotes are convenient. They come with dual collars and a single, which you can buy depending on your will. And they both have strong shocks. 

However, this one has an edge over the previous one because of the silicone that’s been abundantly used. The remote, as a result, feels premium. It’s very convenient since you don’t drop it easily. 

I wish I could say the same for the collar. Its plastic clasps, God knows why the company had to make reservations there, may not be strong enough to hold onto the neck of your dog.

That’ll be an inconvenience if you own a strong breed like Siberian Husky. I’m saying that because of a bad experience with one Husky where he went out and didn’t return with the collar. The plastic clasp had broken off. 

But if you could use the collar in your supervision, there’d be no problem. Not every dog is intelligent or rogue enough to break off from the collar. If you’re confident that yours won’t do such a thing, then use the remote worry-free even from behind a wall. 

Shock Test

As I said, the shock levels are strong but not consistent. You may find a large leap between levels 3 and 4. When I used the collar on a 3-month-old Goldendoodle, the vibration was enough.

I didn’t have to shock her because seeing that the vibration was working was good news for all of us involved. Her leash aggressiveness vanished into the thin air.

Why Do I Recommend The Product?

Whether you could use it blindly or not depends on your faculties. I was able to do it successfully. The remote in all fairness allows that with a simple layout. I like the keypad lock key on this one because it doesn’t take time to take effect. 

What Makes It Stand Out?

Abundant silicone has been used in the remote to make it feel rubbery.


  • Premium materials used in the making
  • Ergonomic receiver 
  • Strong vibration 
  • Strong shock levels 


  • Huge jump between levels 3 and 4

8. Educator Shock Collar

Stopwatch Design

This one’s going to take you by surprise with its remote. I like the idea of the stopwatch design. The shock buttons, both standard, and boost are located on the side with a mode selection/tapping sensation button.

They are easily accessible. The ones on the back are not, however. You’ll have to learn to use them before you’re able to do so blindly. 

I couldn’t do it though. I had to stop using the remote to turn on the light in the collar or change between continuous or momentary stimulation.

Even if you don’t change the latter, though, you could long-press the stimulation button and achieve continuous zaps. When you do so, you’ll see another astounding feature. 

Holding the zap button for more than 1.5 seconds first relays a tone followed by the shock. This helps your dog associate the tone with what’s coming after it. I’ve found it convenient in many use cases.

An 18-month-old German Shepherd responded well to it. He didn’t dig after a few days’ use. 

However, to get to the vibration, I had to read the manual to know how to change the setting. 

Yes, the remote is convenient but these things may confuse you. Most of the users think this product doesn’t have all three modes of correction until they found it out in the user manual. I was one of them.  

Shock Levels Test

The shock levels are not strong at the start but as you move past level 10, things get hot. So, you may want to test it first on your hand before putting it on the dog.

One thing is for sure, though, the stimulation will work with your dog as it did with a head-strong husky I trained. She wasn’t head-strong anymore after receiving level 9 zaps for a few days. 

My only complaint with this one is the battery. The company needs to work on improving it. 

Why Do I Recommend The Collar?

I recommend it for its brilliant stopwatch design.

What Makes It Different From Others?

The Pavlovian tone is quite unique in every aspect.


  • High levels of stimulation 
  • The ergonomic stopwatch design is convenient 
  • Pavlovian tone works great in positive reinforcement 
  • The Biothane strap makes the collar snug 


  • Battery life could be improved 
  • The receiver is too big 

9. Garmin Delta Sports

Barking Limiter

The Garmin Delta Sport Shock Collar isn’t just a shock collar. It has intelligent configurations for different behaviors. You get 5 different mixes of features that you could use to correct 5 different behaviors. 

Barking is one of them. The collar allows you to correct it manually with the help of the convenient remote or automatically with the BarkLimiter.

You have to press and hold the power on/off button to get into VCM and from there, you’d be able to correct the incessant barking of your dog, should you choose to do it. 

Read the manual before selecting any configuration because you don’t want to end up zapping your dog unnecessarily. When it comes to that, the BarkLimiter will not shock when your dog whines. But we aren’t irritated by it, are we?

What you could be irritated by is the non-constancy of the BarkLimiter. It may work well one time but the next minute, it may stop working. That’s the only problem I found out when I was correcting a 4-month-old Labrador.

She was a high-energy pooch with a liking for chasing cows around the farm while barking with as much energy as she could muster up. 

Continuous Stimulation

I love the continuous stimulation. It works wonders on dogs that ignore momentary shocks. But you should check out the level of shock before pressing the continuous button. 

Also, be wary of the LED on the collar when you turn on the BarkLimiter. It will turn red. Do not confuse the red color with a warning for low battery. 

Why Do I Recommend The Product?

It has dual operation – both manual and automatic.

What Makes It Different From Others?

It’s the toughest one and thus, lasts longer.


  • Auto and manual modes work hand in hand 
  • Sturdy construction 
  • BarkLimiter and 4 other configurations 
  • Stimulation levels are suitable for strong dogs 


  • Tricky manual 
  • Confusing LED light on the collar

Frequently Asked Questions

Let’s take a look at some related FAQs.

What is the most effective shock collar for dogs?

The most effective shock collar for dogs is the Dogtra 1900S series. I love it for its sturdy design, High-Intensity Pager, and the ability to shock the dog continuously if it doesn’t yield.

I haven’t seen any dog not listen to me when the behavior’s been corrected with the 1900S. I could easily say that this is the most successful and effective color.

How many volts does a shock collar have?

The static shock we experience in our daily lives stays around 25000 volts. As compared to that, the shock collars give out around 20 volts, some estimations would say.

How many volts a collar delivers depends on the collar itself, too. If you’re concerned about the shock level, make sure you select the one after which the dog stops the activity you want it to stop.

Also, listen to it when you administer the shock. If it yelps helplessly, stops shocking it asap. 

What’s the maximum voltage that the shock collar has?

The maximum voltage could be about 4000 volts. However, that depends on the manufacturer. Many collars available today in the market give out small voltages, enough to make the dog uncomfortable when he performs an undesirable function. 

Can a shock collar change the behavior of a large dog?

Every dog has its personality. Whether a collar would change a large dog such as a Great Dane, depends on the dog, the handling of the owner, and the collar itself.

I have used Dogtra 1900S on many big breeds and it hasn’t disappointed me in correcting their behaviors. 

Will A Shock Collar Stop A Dog Fight?

A shock collar may or may not stop a dog fight. I wouldn’t recommend zapping the dog during a fight because that might let the other dog overpower it and potentially harm it.

I recommend that you should be vigilant enough to spot any potential for a fight and try to zap your dog to listen to you before it lunges forward.

During the fight, however, if the owner of the other dog is cooperating, you could zap your dog while he or she tries to remove his or her dog.

Why Is My Dog’s Shock Collar Not Strong Enough?

Your dog’s shock collar may not be strong enough because it may be built that way. You should check with the manufacturer or do some research yourself to see if it is indeed a strong shock collar. Normally, these collars are signified by high levels of stimulation, longer battery life, and brand awareness.

Wrapping Up

You’ve read about the collars I suggested above. They are the strongest collars for a strong dog that does not honor recalls. Before using them, make sure that you read their manuals.

They were selected by keeping their shock intensity. Or, you could say, their shock levels are hot. Lastly, I want you to listen to your dogs when you use the collar on them.

They are going to tell you if it’s working on them or not.
