How It Works: Safe and effective for all dogs over 10 pounds; the system delivers mild corrections through two contact points on the collar that touch your dog's neck. If your dog crosses the established boundary, a correction will be sent to get your dog's attention, but will not harm him/her. You can customize the level of correction to match your dog's temperament, and the adjustable collar allows you to create a perfect fit for your dog.
