What’s the Strongest and Most Powerful Shock Collar For Dogs?

Despite your best attempts, your dog hasn’t learned polite manners just yet. Although it may seem like a cruel thing to do, shock collars are typically very effective tools to curb bad behavior in dogs.

It’s important, however, that you procure the correct kind of shock collar for your dog to ensure that it receives the right level of shock. This article will discuss the strongest shock collars for dogs and which is the best for your dog.

Quick Facts – E-collars and shock collars keep getting better and better. Overall the market has grown more than 150% from 2016 through 2021 (source). According to Sgt. Rod Hampton, Canine Unit Supervisor of the Round Rock (Texas) Police Department Canine Unit, the most effective use of e-collars is controlling dogs at a distance (when verbal commands are harder to hear) and preventing accidental bites (source).

The Top 5 Strongest Dog Shock Collars On The Market

Negative reinforcement, when mixed with positive reinforcement, can be an excellent way to weed out bad behavior in your dog. It helps them understand that when they do something right, they get rewarded, and when they do something wrong, they get punished.

Having the right collar is important because a collar for a larger dog can seriously injure a smaller dog when used. Whereas a collar for a smaller dog, when used on a larger dog, might not subdue them enough.

Your dog’s hair also needs to be considered. If the dog has long hair, then the spokes on the collar won’t be able to touch its skin.

Here are the top five powerful shock collars that you might want to consider for your dog.

A Quick Note on Shock Collars from an Expert

We reached out to Rick Alto, a Certified Professional Trainer over at SpotOn Fence to get his take on GPS fencing for dogs. Here’s what he had to say.

First, I think use of the term “shock collar” does a disservice to the wide range of e-collars that exist and should really be thought of as communication tools, rather than punishment techniques.

To properly use an e-collar, you should first teach a simple skill, like “sit,” then layer on
use of the e-collar with treats to create positive association through positive reinforcement.

By layering the e-collar over commands, the dog learns that their decisions may result in a low level correction, much like a tap on the shoulder – and the dog should be taught to understand that the stimulation is coming from you, the handler.

The idea is to take the dog’s attention away from the thing that they could harm, or could harm them, and bring it back to the handler. We use tools like this every day to shift our attention – the beep of the kitchen timer, the alert that reminds us to buckle our safety belt, and so on.High quality e-collars have a stimulation range that goes from 0-100.

Once you find your dog’s working level, usually something under 10, a stimulation most humans cannot feel, it acts more like a pager to nudge your pup to correct their behavior.E-collars are extremely effective communications tools, and much more efficient than other techniques like clickers.

It’s also important to remember that they can be life saving by stopping your dog from leaving the yard, running into traffic or chasing after something they shouldn’t.

Thank you!
