Unlike other e-collars, Dogcare Electronic’s training collar offers you a special flexibility to choose different modes and sensitivity levels to use with your dog. Use the beep mode to stimulate your dog with a sound rather than a vibration. Use the vibration mode to give your dog a gentler stimulation. Use the shock mode without fear of damaging your dog’s flesh. This collar offers 99 static levels so you can confidently set the right level for your dog. Have multiple dogs to train? This tool give you the ability to control and adjust individually up to 9 collars with one single remote. At a 330 yards range, the remote gives you ample control of behavior at a long range.
