Look, the best thing is to find the real reason why your dog won't stop barking and solve the problem. I have found a device that I advise you to use only temporarily, this Ultrasonic dog bark control has received a lot of good reviews on Amazon, it has no ON/OFF button which is not a problem, but it seems that those who have tried it are satisfied and their dogs don't bark excessively like before. But it must not become a solution that lasts even if it is safe for your dog !
