Scared of doggies? Don't want to resort to extreme measures to keep them off your yard that could get you into trouble with the police? Well, the Animal nuisance Repeller from Viatek is designed to keep animals away from you without any violence involved.
Essentially, it emits a high-frequency sound that makes dogs and other animals with sensitive hearing really annoyed. Rather than hang out, barking and peeing on your flowerbed, they'll hightail it to more pleasant pastures. And you can stop freaking out about getting bit, even though, really, that's pretty rare. But hey, do what you gotta do.
