The DogCare EC11 Dog Training System is a rechargeable dog collar with three different training modes that are safe for your furry friend—beep, vibration and shock. These modes help teach your pup basic obedience commands and can help improve her behavior problems. What’s especially grr-eat about this collar, is that it comes with a remote to help reduce the chance of accidental shock—the unique security keypad lock prevents you from accidentally activating the shock mode. When you are ready to activate the shock mode, you have the option to choose from level 1-99. The DogCare EC11 Training System can support up to 9 dogs with just one single remote transmitter. The remote range gives you wireless control for up to 330 yards and you can have peace of mind knowing that the long-lasting rechargeable, lithium-ion battery life ensures effective dog training.
