Petsafe Indoor Bark Control

This device uses ultrasonic technology to discourage barking. When your dog barks, the Indoor Bark Control device gives off a high-pitched, annoying tone that most dogs can hear, but humans can’t. With a little practice, your dog will soon learn that he won't hear that ultrasonic tone when he doesn't bark.

The Indoor Bark Control is small and about 3 inches tall so that it can be easily used on a table or hung on a wall or door frame with the included adhesive-backed hooks. Just make sure it's in whichever room your dog barks the most! The Indoor Bark Control works best for families that only have 1 dog because every dog within the range of this device will hear the high-pitched tone, even if they aren't the one who is barking.
