Unlike most traditional "shock collars" these E-Collars use a form of stimulus that targets the neck muscles of the dog; mimicking the loving touch of their mother. With stimulation levels ranging from 1 to 100, you can adjust the stimulation to a level that is best suited to gently communicate with your dog. This “best level” can be locked to prevent over-stimulation and easily adjusted for a higher distraction environment when necessary. This level of control gives these E-Collars the clear advantage. We offer trainer systems that fit your dog's breed, size, and fur type.
