Ultra Sonic Bark Controller

The Advanced Indoor / Outdoor Ultra Sonic Bark Control for Dogs by
Acquiesce is the perfect device to help control your dog's nuisance
barking. The device is bark activated and once triggered the Advanced
Indoor / Outdoor Ultra Sonic Bark Control for Dogs emits an ultrasonic
sound (inaudible to humans) which interrupts the barking and gradually
discourages further nuisance or boredom barking. The Advanced Ultra
Sonic Bark Control for Dogs by Acquiesce is weather resistant and can
be used indoors and outdoors for a complete bark control solution. The
device can be operated on two or four 9v batteries. Four batteries
would need to be replaced less frequently. Batteries not included.
