Turn-on the BarkCollar™ and and set it to ‘V’ (Vibration). Put the BarkCollar™ on your dog. Observe the dog barking and look for a response such as a head shake, ear twitch, or change in barking behavior. If you do not see a response, or if the dog continues to bark with no apparent reaction to the collar, increase the setting one level and repeat the process. When you see a subtle reaction from your dog, that setting is a good place to begin training.
