My dogs just eat the water. I would take the dog on a 1 to 3 mile jog. This will drain his nervous energy. Then take him around people. The dog will be in a more mellow state. When the dog does good, reward him. I like using frozen carrots because it won't make them fat and it reminds them of snapping bone. Snapping bone, satisfies their primal senses. I did this for two years and it help end my dogs fear aggression.
Get a squirt bottle, fill it with water and anytime your dog barks, just squirt him with water in the face. It Won't take long for him to get the message.
I feel squirting them would work but good idea for cats, it would be better to be calm but assertive and tell them no barking ir stop then lightly slap their butt if they bark at the doorbell and they bark ahain be calm and assertive and if they dont bark when you ring it give them a treat
