No bark collars have been growing in popularity over the years as an easy way to get dogs to stop this annoying habit. One reason for their popularity is it allows owners to not have to retrain the dogs themselves, but it allows the collar to do the training for them.
In the long run it is always best to retrain the dog yourself rather than relying on the collar, but the collar does offer a convenient alternative to taking the time to train your dog.
No bark collars can be found that just use citronella or an inert gas. These are arguably safer than shock collars to help keep your dog quiet.
Citronella is not harmful to your dog, but most dogs do not like the smell of citronella, and will soon stop barking if they learn that they have to smell it every time they do this.
Citronella collars are easy to use but one of the main things is that you have to make sure that the reservoir chamber always stays full.
At the beginning of the retraining, you might have to refill the reservoir frequently. Remember if the reservoir runs empty your dog will not receive any negative conditioning from barking.
So while no bark collars are convenient you must still do your part and make sure that the collar is working properly and properly supplied.
If you choose to use an electronic no bark collar you should check it frequently for proper settings to ensure that your dog can wear it safely.
