There are behaviours of our animals that make us laugh, but there are also others that make us feel hot-tempered. Observe how you are doing in training. If you become angry, annoyed or impatient, interrupt the training immediately. This is not serious and can happen to anyone. It is only a pity if you then continue training and send wrong signals to the animal or even take out your displeasure on the animal.
Take a break for a moment, take a deep breath and think about what upset you and how you can avoid it. If you have no idea at this moment, take your time to think. You would rather not train any more on this day than in a bad mood.
The training should be fun for both the animal and the person. This will make it successful and efficient.
