If you have searched ‘strongest shock collar for dogs in the market’, chances are that you are having trouble training your dog with a cheap, low-quality e-collar.
But don’t let the title of this article put you off. Shock collars have been used by canine trainers for over 20 years. They were initially designed to train police and military dogs who need rigorous training because their job requires it. You need immediate obedience when security is on the line.
Over time, big hunting dog breeds have been domesticated more and more. For security reasons, people have kept German Shepherds, Huskies, and Rottweilers to keep burglars out.
Even though all dogs are man’s best friends, these breeds are more difficult to train than others. The reason is their temperament and their large sizes. Dogs with stubborn temperaments require more patience and rigorous training. It is difficult for pet owners to train large dogs with a leash collar. Mostly because they tire you out and exhaust you.
The purpose of a shock collar is to get your dog’s attention without having to pull their heads from side to side. It annoys the dog and frustrates you.

If you use a shock collar right, by talking to an expert, you will find out that a good quality shock collar is harmless.
There are a lot of cheap options available as well but they provide inconsistent stimulation and sometimes malfunction or misfire.
Therefore, it is highly important that you buy a strong and sturdy shock collar to train your dog the right way.
1: Dogtra 1900S Series Ergonomic Dog Collar (Strongest Shock Collar for Dogs)
Special features: ¾ mile range, IPX9K waterproof, ergonomic design, 127 stimulation levels, LCD screen with a rheostat dial, High-Performance Pager (HPP) mode, stainless steel contact points with microbial plastic
The Dogtra 1900S is a versatile choice for dogs of all ages and all sizes, but it is best for large and stubborn breeds.
What makes this collar brand special is that it is very durable and reliable but comes with a heavy price tag.
Given the incredible feature it offers and considering the fact that you don’t want a shock collar to be of cheap quality, I think you can compromise on the price!
The Dogtra’s strength comes from its 127 levels of stimulation and IPX9K water resistance. With so much adjustability, you can easily find the appropriate level for your dog even if it is very small.
You can choose between ‘nick’ and ‘constant’ stimulation. The constant one provides a 12-second shock that no dog can ignore. This is one of the reasons why Dogtra is among the strongest shock collars!
Both the receiver and collar and IPX9K are waterproof and tested to withstand extreme weather conditions. It is built for hunting and gives you a ¾ mile range to take your dogs with you wherever you go.

The SportDOG 425X is going to give you better control over training with its Blind Operation Design. Your dog won’t know the static is coming from you because you won’t need to look at the remote while operating it.
Its powerful battery will last 50-70 hours with a single charge of 2 hours. This is so useful as most shock collar owners want to be able to take their dogs out for campings or outdoor trips and get worried that they won’t have much battery life outdoors.

Frequently Asked Questions About Strongest shock collar for dogs
Do dog trainers recommend shock collars?
Shock collars aren’t the first training choice of professional trainers. They recommend shock collars only in cases where the dogs are very large, need distance training and strict obedience.
Most trainers prefer using a reward-based training method over any aversive method.
A study by Cooper et al. in 2014 showed that recall training using a reward-based method was just as effective as training the same behavior using shock collars.
How long can you leave a shock collar on a dog?
Experts and manufacturers strictly advise that you should never leave a shock collar on a dog for more than 8 hours or overnight. Keep it out of the reach of children and always take it off indoors when the dog is napping or eating.
Experts also recommend that you continue to check the skin underneath the dog’s neck regularly. Check for burns or rashes and other skin irritations.
If you find that the skin has started turning red, discontinue using the shock collar and consult your vet.
When should you use a shock collar?
Shock collars should only be used as a last resort and after proper consultation from a professional dog trainer.
Do not use shock collars on puppies 6 months or younger. First, try other positive reinforcement techniques. If all else fails, only then use a shock collar on your dog.
If you are worried about your pup’s constant barking which has started annoying the neighbors, use an anti-bark collar with a safety auto-off system.
How do I adjust my dog training collar?
Adjust the dog training collar on the narrowest part of the neck, behind the ears. Snug the strap down to get a proper fit.
Each e-collar comes with a set of long and short contact points. Dogs with thick hair need long contact points and those with short hair need small ones.
How tight should the shock collar be?
You also don’t want it to be too tight. Make sure you can slide one finger between the contact point and the dog’s neck.
Do shock collars make dogs aggressive?
Shock collars are a tool. And like every other tool, if given into the wrong hands, can exacerbate a problem instead of solving it.
If you use a shock collar as a form of punishment, your dog will recognize it. Then, instead of becoming calmer, it will become aggressive.
Dogs need to be able to trust their owners. They should learn that their owners always have their best interests at heart. To communicate this to your dog is to make sure that no training tools are being used as abusive devices.
Do shock collars work for big dogs?
Shock collars are especially useful for training big dogs like huskies or golden retrievers because they can be harder to train using a regular leash collar.
Can you leave a shock collar on a dog all the time?
It is advised by experts that you don’t leave a shock collar on a dog for more than 8 hours and never overnight.
My best pick is the Dogtra 1900S. There isn’t a shock collar more powerful than the Dogtra as it offers 127 stimulation levels, nick and constant shock option, great lifetime durability, and amazing battery life.
Another thing that stands out about it is that the Dogtra is IPX9K waterproof! This is the most advanced technology and you can easily train your dog in the rain or take it swimming!
It is a powerful, high voltage shock collar, perfect for dogs 150 lbs and up. There is no delay between correction and shock delivered. All this makes Dogtra 1900S the strongest shock collar on the market!
