Rowdy dog behaviors can be very frustrating and unsettling to the neighborhood. All that excessive barking and howling in your canine friend needs to be controlled. Dog shock collars come with three modes (beep/sound, vibration, & static shock) which should curb the unwanted behaviors. But what if your pooch is still unruly?

That is where you need the most powerful shock collar in the market to make your dog obedient and silent. It explains why the manufacturers of these shock collars are increasing their production. Shock collars feature a receiver on the collar and a remote that you use to send signal and administer static shock to your canine pal.

How Many Levels?

Sometimes, a dog shock collar includes three (3) stimulation levels while others come with four (4) stimulation levels. You can choose these levels via the remote control depending on how unruly your dog is or even the breed, and how it responds to the shock.

The market has a pool of different shock collars. As such, you should aim for a heavy-duty and robust one, especially if you have a strong dog breed. There are cases where heavy dog breeds have broken sub-standard collars which means you must choose the one made of high quality material.

So, which are the best most powerful shock collars on the market? What do you consider when choosing these collars? What is there to know about dog shock collars? If these are the questions you are asking yourself, then you are in the right place.

5 Best Most Powerful Shock Collars for your Dog

What to Consider when Choosing the Strongest Shock Collar

With the flooding shock collars in the arena today that advertise as “most powerful dog shock collars”, it is easy to get lost and invest in the wrong one. From strong build with high-grade materials to water resistance, effective range, battery life, and size, many factors come into play.

To simplify things for you, our dedicated team of experts conducted in-depth research and came up with these eight considerations:

  • High-Grade Material – Look for shock collars that are made from high-quality materials that do not break easily. You should also consider how adjustable it is as well as how snugly and secure it fits your dog’s neck.
  • Size & Weight – The last thing you want is to invest your money on a shock collar that is either too big or too small for your dog’s neck, or one that’s too heavy. As such, you should measure your dog’s neck to find a shock collar with a suitable size and weight for your dog.
  • Operational Range – How much coverage does the shock collar have? Dogs love walking and playing, especially during outdoor activities. A powerful shock collar should have a wide operational range with no barrier to administer commands to your far away dog.
  • Water-Resistance – It goes without saying, almost all dogs love swimming. As such, the dog shock receiver should be waterproof to avoid accidental shock. This feature is also important when you are bathing your canine friend or get caught in the rain during walks and such. 
  • Battery Life – With an unruly canine, you are going to use the shock collar and remote often when curbing their undesirable behavior. So, it should have a good battery life that serves for many hours and if possible, rechargeable. Make sure it charges within 2-3 hours.
  • Versatility & Functionality – How many stimulation levels does the shock collar have? This is crucial as you can choose the level that suits your boisterous canine friend.
  • Warranty – Electronics are prone to faults and breakages which can even happen during shipping or storage. This requires repair, replacement, or refund. So, check if the shock collar’s manufacturer offers a warranty.

Lastly, price is also a factor to consider. Cheap is expensive! But honestly speaking, not all shock collars that come with a high price tag are of good quality. There are fairly-priced shock collars even for individuals working on a tight budget out there that you will like. Do not strain on cost, but do not go for standard or substandard dog shock collars either.
