PetSafe Ultrasonic Bark Control Dog Collar

Effectively deters barking when worn.

When the microphone picks up the sound of your dogs bark, the unit emits an ultrasonic tone that can be heard by your dog, but is silent to most humans. Startled by the high-pitched tone, the dog should stop barking, as it will associate its bark with this unpleasant noise.

The PetSafe® Bark Control Collar System includes:

• Bark Control Unit
• Adjustable Nylon Collar
• (2) CR2032 Batteries
• Operating Guide
• 1-year manufacturer warranty

Fits Small to Large Dogs - The collar fits dogs over 8 pounds and neck sizes up to 28".
