The time your dog learns not to bark depends on your pet`s character and habits. For the first two weeks, it’s better to wear a collar almost everywhere. After that, your dog will know that it should be silent even without a device. When it happens, you may use a collar only for walking or training. Also, if your dog likes to bark at night, then wear a bark collar in the evening, or, on the contrary, if your dog is more active at day, apply a product during this time.
