Sonic and Ultrasonic bark control devices
PetSafe Ultrasonic Indoor Bark Control Devices Twin Pack [PS010 PBC17-14777]
Sonic and Ultrasonic bark control devices are good ways to deter your dog's annoying barking or stop your neighbours dog barking.
Effectiveness is dependent on your dog's sensitivity to ultrasonic or sonic waves. For more stubborn dog breeds, static or spray bark collars are preferred to the sonic or ultrasonic devices.
