Rewards increase motivation and facilitate training. To be effective, it should be meaningful to the dog, that his master should congratulate him with a touch of hands and a warm tone of voice in sync with success in practice. On the other hand, reprimands should be given to punish wrong behavior or harmful behavior, but should be used only if the dog is caught doing so. It should be noted that positive reinforcement with rewards is much more effective than negative reinforcement with punishment.
Language
The language used should be tailored to the animal, with simple, short and often repeated commands. That way, the dog better understands the tone given to words than the meaning: the tone used must therefore change depending on whether you give orders, congratulate or rebuke. Making a move is also an effective way to communicate with dogs.
