Innotek's economy, battery-operated bark collar helps your dog teach himself to remain quiet.

Bark collar has only two skin sensors and is light weight

The auto-set feature makes this collar incredibly easy to use, with no external controls or settings. When annoying barking begins, the bark collar's sensitivity setting senses the vibration of the dog's vocal cords and administers a brief 1/2 second harmless but unpleasant correction. If barking continues for another 3 seconds, another correction is given and repeated at 3 second time-out intervals until the barking stops.

The dog learns very quickly that the barking initiates the correction, stops barking, and the training is complete.

Innotek BC50B bark collar features:
• Small, 3 ounce collar box unit
• Seven correction levels can be programmed by the user to suit every dog's temperament - very low stimulation for very sensitive dogs to much higher levels of correction (still harmless but more unpleasant) for the stubborn barker.
• The collar can only be activated by the barking of the dog wearing the collar, not by other dogs' barking or loud noises nearby.
• Bark collar can be used indoors or out
• Collar can be left on while you're away.
• Comes with a receiver and an adjustable collar
• Replaceable 6 volt battery (included)
• water resistant.
