What Might Be The Best Way To Use An E Collar On A Dog?

For professional advice on using a shock or e collar, see a vet or a professional dog trainer, or animals expert.

But, in general, good e collars come with instruction manuals and guides that tell you how to safely and effectively use their product.

Look to buy from a reputable company that cares about the safety and well being of the dogs.

The best way to use an e collar might be as a temporary device for associating negative or undesirable behavior with a cue (such as a vibration or noise), or a stimulus (such as a nick/static stimulus).

They can be used to teach or retrain a certain behavior, and then put away. They may only be brought out again if your dog/s forget that behavior, or need retraining.

So, really, they could be used ideally as a temporary training and teaching tool (not permanent) for happy and healthy dogs. 

If you notice any negative side effects to your dog’s physical or mental health from using an e collar, discontinue use immediately.

The benefits of an e collar might be:

  • You don’t have to set the collar to shock. You can set it to vibrate or sound.
  • The lowest shock settings on good e collars will provide a small amount of discomfort, not pain
  • The feedback to your dog is instantaneous and not delayed
  • It works at range
  • It saves you shouting and getting frustrated
  • + many other benefits
