Opinions on the bark without collars for puppies?

Hi Im wondering how people with no experience with dogs bark feel about necklaces .. I have a dog, so I want to teach him not to yap the face of all the time but she is not really grasp the concept. When I put in a cage is absolutely crazy. And I ignored him, of course, so she does not associate with me picking crying .. but her until my neighbors are starting to complain!

No collars bark shock when the puppy cry. Puppies bark. The collars are bad. If you want a dog bark, get a cat.
