PetSafe Outdoor Ultrasonic Bark Deterrent (line)

A mountable unit that emits ultrasound automatically when it detects barking within range.

Not for: Dogs behind solid fences or walls, since ultrasound does not pass through them.

Line of sight: The device must face the dog with no wall, fence or window in between. Ultrasound is blocked by solid objects.
Short effective range: Expect it to work only when the dog is fairly close, not across a yard. Ultrasonic sound fades quickly with distance.
Dog's hearing: Do not count on it for older or hearing-impaired dogs. Dogs that can't hear the frequency will not react.
Habituation: Treat it as an interrupter paired with training, not a lasting fix. Many dogs learn to ignore it with repeated exposure.
