Often puppies cry when confined.
Try slapping your hand with a news paper and give the command “Quiet!” in a stern voice. If that doesn’t work try using a squirt bottle or squirt gun. Don’t drown the pup, just give a quick squirt and the “Quiet!” command.
Always give a verbal command with a disciplinary action. Be firm! Remember you are training them.
A squirt gun is also a good method to use when trying to teach a puppy to not bark excessively.
It’s not a good idea to let children train a new puppy, they are not consistent. Once the puppy is trained, you can allow kids to reinforce what has been taught to the pup.
