My puppy always thinks I am playing because my voice is high, what do I do?

I sometimes have the same problem, my voice is just naturally a little high pitched. It's important to make sure you do use a more commanding type of voice when asking for something. For example, when playing or talking to a baby we say "no" in a way it is communicated effectively; you can imagine in your head that universal tone for the word "no." When commanding something, like "sit," use that same type of idea. This should give more of a decipher towards the playing voice vs. the command voice.
