3. Loud talking or yelling will annoy your dog
Raising your voice is an evolutionary tool humans were given to emphasize serious matters. You raise your voice to demonstrate that you are not joking around and sometimes a loud voice or yelling is used to discipline. Your dog will automatically interpret yelling as something that they did wrong. If you do this enough times, he or she will get annoyed and soon will be confused with your temper. The best bet here is to stay calm and maintain a reasonable voice when you are discussing something. If you need to yell, consider leaving the room or area and do so, but save your voice and try not to yell if possible.
