Top Best Shock Collars for Aggressive Dogs

1. Pet Resolve PTS 1200

Aggression in dogs can present itself through various behaviors like grumbling, howling, teeth-baring, snarling, and snapping at the air.

However, a problematic behavior that results in biting is considered the worst.

And that is why I introduce the Pet Resolve PTS 1200 as the first and best training collar that can help you effectively manage all these behaviors of your aggressive dog.

The currently available Pet Resolve PTS 1200 version is upgraded to many new features making it one of the most reliable dog training solutions.

This remote training collar offers 3 training stimulations: Loud Beep, Vibration, and Shock. The shock correction can be continuous or momentary at 10 intensity levels.

These options allow the trainer to try multiple combinations to find the perfect sensitivities for your aggressive dog.

Removing the shock function is a highlight feature you find in these e-collars. Switching the default contact points with the given plastic contact points converts the Shock into vibration.

This allows you to eliminate the use of the Shock or rather use it as a vibration instead.

This dog training collar features a remote control that enables communication over a super-long ¾ mile range. It means you will have reliable control over your dog, even during distance training. Also, your dog gets to enjoy the greater outdoors too.

Using the memory function of this training collar, you resume the training session where you left off, and you can apply the anti-bark function to control your dog’s excessive barking.

Also, you can use the LED light on the night mode to guide you and your dog during night walks or training.

This dog training collar is made using the highest quality materials, so the receiver of the collar is 100% waterproof, making it ideal for all water activities, including swimming.

You can also accessorize the receiver with extra-long prongs to ensure better skin contact if your aggressive dog is long-furred.

As for the size, this dog training collar is adjustable to fit all dogs 15 lbs and over, so it is highly likely to fit your dog no matter the breed or size.

Answering your question: Why is the Pet Resolve PTS 1200 first on the list? It’s the highlight feature I mentioned above that makes all the difference.

A dog owner and a professional trainer will both agree that having the versatility to omit the Shock is a game changer, and not many training collars offer this. 

Key Features:

  • Three training modes: LoudBeep, Vibration, And 10 Levels Of Shock Modes for a versatile training session.
  • ‘Remove the shock function’ lets you use it with only a beep and vibration.
  • The memory function allows you to pick up where you left off.

A Buyer’s Guide to Choose the Best Out Best for Your Aggressive Dog

A boxer dog is looking at the camera.

This buyer’s guide will highlight and explain a few features you must look into before making a shock collar purchase to work on your dog’s aggressive behavior.

This will ensure you understand how each feature contributes to the overall function of the collar that gives you effective results.

Purchase Intent

As you already know, shock collars should only be used as a guidance tool to train your dog and never to punish your dog.

Although clearly, the purchase intent over here is aggression management, you must be patient and stick to the intent throughout the process because training aggressive dogs can sometimes become frustrating. 

A suitable collar that will help your training with aggression management is the Pet Resolve PTS 1200. I recommend starting from the tone and vibration mode with a reward-based positive reinforcement training technique.

If necessary, you can resort to the shock feature based on your dog’s response.

Size and Temperament of Your Dog

Various dog breeds come in various sizes. They even vary within the same breed. So always consider the size and strength of your dog. 

Similarly, some dogs, although aggressive, can be sensitive compared to other dogs. Their aggressive behavior may be triggered by certain factors surrounding them. It greatly helps if you know how your dog is in a general sense.

Observe your dog’s behavior and aggression triggers. Considering all these factors, you have to make a judgment call and decide on the strength of the static shock feature of the collar. 

Effective Communication Range

A dog training collar with reliable long-distance communication is always a great choice because it means you get to train your dog in large outdoor areas while having control over the shock collar to correct any unacceptable behavior of your dog instantly.

This all gives the opportunity for your dog to play and have greater outdoor areas.

Reliable Training Modes With Intensity Adjustability

The more modes, the better the reliability because it facilitates versatile training. The shock feature is a given but check for the other basic warning and correction modes like the Tone and vibration mode.

More importantly, check if they come with intensity adjustability to find the best intensity that works for your dog’s aggressive behavior.

In addition, you can also check if the Shock is usable on different styles like Nick and continuous.

Quality of the Collar

To determine the quality of shock collars, you have to look into the feasibility of the design and the materials used to craft the collar, like the collar strap, buckles and the strength of the plastic used for the receiver.

This overall crafting will, in turn, contribute to the collar being waterproof and or impact resistant. So checking these will help you decide if you can use it long term, even around water.

Battery & Run Times

For a reliable power supply option, choose a high-capacity rechargeable battery that gives long runtimes. This eliminates the need to replace batteries and recharge frequently so you can reliably use it on training for a long time.

For example, the Pet Resolve PTS 1200 gives you long runtimes so you can use it for days of training.

Price to Function Ratio

The market is flooded with many shock collars. So there is competition, meaning you can find collars as cheaply as possible.

Now cheap does not mean the collar is low quality and cannot perform the function, but at the same time, it does not mean otherwise either. 

So I recommend considering all the above features and allocating a decent budget to get a good quality shock collar. 

Why Use a Shock Collar on Aggressive Dogs?

a aggressive dog barking

Shock collars are used as a tool to divert a dog’s attention from the act in performance. Unlike a prong collar that causes pain and discomfort, the Shock takes the dog by surprise, effectively grabbing the dog’s attention.

At this exact time, the trainer should communicate to the dog that the aggressive behavior is unacceptable. 

Redirecting the dog from the behavior is a large part of the training process, and that’s why using a shock collar is needed.

The effect of a shock collar coupled with proper training techniques, like reward-based positive reinforcement training for communication, will provide the best results.

The whole point here is to catch the dog in the act through the Shock and teach it otherwise. And for this, precise timing is important.

For dog owners who have no prior experience in training, I suggest consulting with a professional dog trainer to understand the best way you can set the training foundation for your aggressive dog. 

Aggressive Dog Shock Collar Training Tips

1. Introduce the Shock Collar to Your Aggressive Dog

It is highly recommended by many professional dog trainers to initially introduce the shock collar as a regular collar to allow your dog to get accustomed to it. 

Secure the shock collar properly around your dog’s neck and ensure the contact tips touch your dog’s skin without causing any discomfort.

Leave the collar on for at least a week before your dog’s obedience training. When you start using the Shock, it helps you establish that the collar has no effect, but the bad behavior is causing the disturbance.

2. Be Patient and Help Your Dog Understand

If your dog is new to e-collar training, the change may initially be confusing and awkward. We want the shock collar to distract your dog and redirect its attention to the trainer. We don’t want your dog to get used to this new experience. 

It is important to use the shock collar precisely during dog aggression and show your dog that it is unacceptable. Use basic commands and the correct training methods to communicate with your dog. Praise and reward your dog if it stops what it is doing.

3. Take it Slow

To help your dog understand better and faster, don’t ever start from or increase on to high shock intensities at once. Work your way from the lowest intensity and observe the outcome.

Repeat the same using the consecutive intensities till you find the level that’s just right to disturb your dog’s aggression.

4. Control the Shock Collar the Right Way

Dogs are intelligent creatures. Never let your dog catch you using the remote control in front of it too often. Your dog may end up figuring you are the reason behind the Shock.

5. With Improvement, Switch to Lower Shock Levels

As you already know, shock collars are training tools used to guide dog training sessions. 

With successful use, you will achieve positive results. When you see more and more positive results, you have to start reducing the shock intensities to the point where you no longer need the electronic collar.

This process helps your dog associate its changed behavior with the correct behavior, and the rewards encourage your dog to stay on track.

Here’s our complete guide on How to train an Aggressive Dog with a shock collar.

Frequently Asked Questions

Yes, a shock collar can help with dog aggression. With proper and appropriate use, it can help with training to decrease aggressive behavior and promote good habits.

No, shock collar training is not cruel when used correctly. Professional trainers should be consulted to ensure the collar is used as a way to disturb or distract the dog rather than punish it.

The Pet Resolve PTS 1200 is the best shock collar for aggressive dogs, as it provides basic training modes as well as additional features. Additionally, it can be used as a tone and vibration-only system.

Final Words

As I kept implying throughout the article, training an aggressive dog requires extra patience and consistency. And your aggressive dog deserves this attention from you. So don’t give up on your dog. 

With the help of a reliable training unit, you can guide your aggressive dog out of all its bad behaviors.

And for this, I recommend choosing the Pet Resolve PTS 1200, which enables a comprehensive training process with all the fancy but useful features it is equipped with.
