The only legal way I know to stop a dog barking is by using
a loud ultrasonic noise.

There are plenty of devices on sale to do that.

As for cats..they can talk.. but they just don't choose
to talk to humans

just be sure not to keep the ultrasound on for too long as the dog will surely stop barking but may start whining ( which is more irritating).
