i have seen and found a website http://www.nutrecare.co.uk that sells these dog training collars, where you have a collar that goes around the dogs neck with a device on the collar that will let off a spray if you press a remote or if the dog barks. could be a useful product for dog training.

Hi,

You can use shock collars for some times to stop your dog barking but it not

the best solution for your dog, you should try proper training to your dog.
