Do Bark Collars Actually Work?  

i am not sure if dog collers work or not but we have dogs next door rot wheelers and they bark alot and i am not fed up with it and i am a cat person but maybe you should try it and see it might work for some dogs other maybe not

I used one many years ago for a very large and very loud dog I used to have in town, and it did work for me.

He barked for just a day or two more, and then I could see him start to bark, but wouldn't.

So I know they worked in that case.

Are you talking about the sonic collar or the shock collar?

I used the sonic one.

Hi,
Yes,Bark Collars do work but not on all the dogs.I would personally advise you not to use them because they make dogs your slave not your friend.I think you should find out why your dog barks so much and should consult a vet.Every animal could be treated with love,you know.
Have a nice day.

i dont know i've never tried one
