Dogs are Extremely intuned to your body language and voice intonations
If you sound angry .... they are going to react to that anger even if they do not know what you are saying
For example ... when you find that your pup pooped on the carpet maybe yesterday
If you show anger your pup might run and hide or put his head down
But he can in no way understand what you are so angry about
When I tell my Zach NO BARK!
He comes over to me and gnaws on my fingers complaining
It's so funny .... you can tell he's asking permission to bark
