Large dogs are often cuddly and friendly and can make great companions. Their larger size means they bark more loudly and can be harder to control. A large dog barking can make it more frightening for strangers than a small dog barking.

Although you are sure your dog will not hurt anyone, it doesn’t mean other people will not jump up and down when your dog barks or if they notice you having trouble holding your dog. Barking can also be a problem for friends and family, and it could lead to isolation.

It is possible to train your big dogs. A bark collar uses negative reinforcement to make it easy and quick. So that you have more time to train your dog and less research, we’ve compiled a list of the five best shock collars for large dogs.

It is difficult to train dogs to stop barking if you wait too long. Training older dogs can be difficult because they tend to be more stubborn than younger ones.

How to choose a shock collar for large dogs?

It can be hard to choose the right shock collar for your dog. This is especially true if you are looking for a shock collar powerful enough to handle large dogs.

We have compiled a list highlighting the most important aspects to consider when selecting an e-collar that will fit your large dog.


It is important to consider the size of your dog when choosing a collar. Large dogs can weigh up to 250 pounds and are typically over 60 pounds. In fact, the largest dog was an English Mastiff who weighed in at 343 pounds.

Although this is not common in dogs, it is worth noting that some breeds are quite large. These extra-large dogs will not be able to use the shock collars that we have reviewed, but they will fit most large dogs.

A training collar is often sized according to the dog’s neck circumference. A Great Dane may be heavier than a medium-sized dog, but their necks will not change much.

Most shock collars can be adjusted and have varying lengths, so you don’t need to measure your dog. It should work for any dog that falls under the “large” category, as long as it states it is suitable for larger breeds.

Different Correctional Methods

Shock collars shock your dog by delivering a small amount to their necks. This starts them and teaches them not to bark at stimuli.

Every dog is unique, and not all dogs will respond to shock training. They may not feel the shock, but they will continue to bark even if it isn’t bothering them.

Some shock collars come with vibrations, lights, and sounds to correct behavior. Some dog owners consider vibrations to be more humane than shocks. However, they don’t cause pain.

Your dog will be distracted by lights and sounds if they start barking or display other undesirable behaviors. They will not cause pain or discomfort to your dog.

The least effective method of correcting behavior is the use of lights. They are a great safety feature for nighttime walks, but they don’t help with large dog behavior like barking. Multiple correction methods can be a great feature so that you can test out different ones.

Shock levels

Large dog training collars that are best for large dogs will come with different levels of shock. This allows you to work your way up from the lowest level to the highest. There are many levels, some with one to 100 levels and others with one to 20. Some don’t even have any levels.

We believe that levels are the best approach as your big dog will soon get used to one level and will eventually become less effective.

Level one, for example, will feel a slight vibration on the neck. It might be a bit uncomfortable for your dog to feel this initially, but soon they will get used to it and not notice it.

You would then increase the shock level to ensure that your dog isn’t comfortable wearing the collar. You’ll be able to use the shock collar more effectively and train your dog to bark away.


Dogs of all sizes love water and will jump into puddles. Your shock collar should be water-proof or, at the very least water-resistant.

Your shock collar may not be waterproof, so make sure your dog doesn’t get wet. It’s not easy to do as large dogs love swimming. The most convenient option is a waterproof shock collar.

The shock collar must also be strong enough to withstand any abuse your dog may inflict on it. Your dog is likely to bump into their shock collar on fallen branches or the ground, as well as other dogs. Look at customer reviews and see if they have any complaints.

Remote Control

Many shock collars have remote controls and are not always on. It is because shock collars that are constantly on can cause accidental shocks to your dog.

Unnecessarily shocking your dog can cause confusion and make training more difficult. Large dogs can have a remote-controlled shock collar that you can control. The collar can be controlled remotely to deliver a shock when your dog starts to behave badly.


Training will be done mostly in the home or yard, so there won’t be much to see.

However, the range must still be sufficient to allow the collar to connect from anywhere in the house. This is especially important if your dog is larger than you are.

The lowest possible range should be 330 feet. Anything less will not work. If the bad behavior you are trying to eliminate is often observed while you’re on walks, then a long-range might be more appropriate.

You won’t be able to discipline your dog if your collar range is less than 330 feet and your dog is digging in the field. You can use shock collars that have a range of up to 1000 feet to immediately discipline your dog and help them to correct their behavior.


The comfort of the shock collar around the neck of your large dog is another important consideration. A shock collar is simply an electrical collar that has electrodes protruding from a metal or plastic prong.

The electrode should not be so long as to make your dog uncomfortable or hurt, and the prong should not be too large that it blocks their view.

Your dog’s movement should be reflected in the shock collar. A rigid plastic shock collar will be less comfortable than a nylon strap or fabric strap.

Frequently Asked Questions (FAQs)

Are shock collars effective?
The effectiveness of a shock collar will depend on the dog. Some dogs find shocks enough to deter them from barking or bad behavior, while others don’t.

Shock collars that aren’t used for enough time often don’t work. The shock collars may cause your dog to be irritable or in pain. They’ll then take off the collar and forget all the training they have done. The shock collar can be used to help your dog stop bad behavior.

Are shock collars effective on large dogs?
Yes, shock collars can be used to shock larger dogs. They will feel the shocks at lower levels than small dogs but will be able to withstand higher levels.
They wouldn’t feel the shock because their skin is too thick to allow the electrode to reach them.
Do not set the shock collar at a higher level because your dog is large. You can start low and gradually increase the shock level until you are sure that your dog is not shocked too much.

Can shock collars cause brain damage?
No, brain damage is not a side effect of a shock collar for large dogs, despite the fact that it can exacerbate preexisting problems.
