The DOG CARE dog training collar must be used as a training aid, not as a training system in itself.
You will need to follow proper training protocols with your dog.
Begin by training your dog to come back to you when you call him. To do this start him on the lead. Using a little pressure on the lead and applying stimulation through the collar, beckon him towards you.
When he comes, stop the stimulation. He will soon start to associate the stimulation with moving away with you. You want him to understand that when he comes to you when you call, the stimulation will stop.
Remember that DOG CARE products are designed to enhance the communication between you and the dog. That means that you have to train your dog using positive reinforcement and teaching him to associate the stimulation as a warning rather than a punishment.
