PetSafe Sonic Bark Control
This remarkably light, one-ounce collar emits an unpleasant but harmless tone to correct your dog�s barking problem. The collar�s cutting-edge, bark-detection microphone can be adjusted to recognize your dog�s unique bark so that no other sound can set off the unit. This collar is most effective when used on small dogs.
The collar has minimized the barking. It does not stop the barking completely but when he barks the ringing noise irritates him and he stops or runs into the house wanting me to remove it. Better with the collar than before. Thank you.
