It is up to you how you reprimand your dog as long as you never use physical punishment.
Some people have trained there dog to master the
'No' command and some people prefer to use a firm verbal command such as
'Leave It' and then a harmless spray from a water bottle as this is quite an effective way of reprimanding your dog.

dog obedience training by training a dog to understand that this behavior is unacceptable before it takes route.
Don't panic as we will cover the
'No' command and other more acceptable ways of reprimanding your dog later in this dog training tips section.
