The short answer
Vibration collars buzz; ultrasonic collars emit a high sound; spray collars puff citronella or unscented spray; static collars give an electrical correction, often escalating. Vibration is the mildest. None address why a dog barks.

Detection matters
Collars that use both sound and vocal-cord vibration correct fewer false barks. Dogtra SMART NOBARK adds a count-only mode so you can measure barking before correcting.
