Alternative correction shock collars are designed for the customer who doesn’t want to use shock collars to train their dog. By utilizing alternative correction shock collars by implementing other methods such as ultrasonic sound and sprays you can still effectively train your dog improving their behavior. These alternative correction shock collars are great and more humane than the already extremely safe shock collars we offer but their only limitation that isn’t an issue with the traditional collars is the range of use is much shorter so keep that in mind while using your alternative correction shock collars.
