How to Train a Dog Not to Bark?

When the dog keeps barking, scold it; if it won’t stop, hold its muzzle and give the ‘quiet’ command. After it stays quiet briefly, release and reward a snack with praise, so it learns silence brings rewards.

Some newly arrived puppies bark from insecurity, so let them sleep where they see you and comfort them with petting. Finally, a sick dog may bark too; see a vet if other symptoms appear.
