From an IDCR Guest Author:
There are three types of anti bark collars you can choose from. One shocks your dog, the second sprays citronella into your dog’s face, and the third emits an ultrasonic noise.
We are going to talk about the third one.
This ultrasonic emits a high pitched noise that humans cannot hear but dogs can. It is really annoying and can get them to stop their excessive barking immediately.
You can get them attached to a collar or by themselves. The ones that you can buy stand alone, look kind of like a small birdhouse you can place in the middle of your home. They even make ones you can place outside to stop your neighbors dog from barking (love this!).
The ones that come attached to the collar are able to be purchased with two features.
You can buy one with noise detection and one with remote controlled access.
The collar with the noise detection released the ultrasonic pitch as soon as it detects sustained barking over a certain noise decimal.
If you buy the one with remote controlled access then you decide when the sound is emitted.
Personally, I like the remote one the best. Quite frankly, sometimes I do not mind when my dog barks and sometimes I do. I would like to have control when the machine is activated.
You know the machine is working because it will either start beeping or a light will come on. You need to check the batteries weekly because they do run out and unlike the other two bark collars it is not always apparent when it has run out of juice.
These ultrasonic bark control collars are indeed humane and are used by many dog trainers. They pose no threat to your dog and will not him or her in anyway.
Keep in mind though that some dogs can get used to the noise and it will become ineffective after using it for several months. If you do notice this you might have to change to another type of anti barking collar.
