Do you have experience with Petsafe deluxe little dog bark collar?
In my experience any type of bark collar is a waste of money as they don’t work. I don’t really agree with the shock ones but they tend to work buy emitting a warning sound first that the dog will here but you won’t and then it will shock if the barking continues. You have to make sure the contact area is shaved so it hasd a good contact. I agree a bottle of water or a tin can full of stones works much better than any collar.
