Ultrasonic Dog Repeller

Lots of people run into the problem of nuisance dogs; sometimes even when a dog isn’t attacking it can look aggressive, or the barking can scare small children.

But there’s a solution out there that doesn’t involve harming the dog – ultrasonic noises that only the dog can hear. For example, there’s the Super DogChaser, the Scram Patrol, and the one that Amazon buyers seem to like, the Dog Dazer II. All of these devices emit a high-frequency sound that dogs find uncomfortable.

They might not work on a dog that is really aggressive, as many reviewers say that’s a problem. But for most people it just might be a more humane (and longer-range) alternative to pepper spray.
