LOL, te joys of puppy hood!

You are on the right track, as Karen said.

She is a puppy, learning things. I ve not heard of putting your hand in the bowl, but it sounds like you did very well, she learned that if she wanted to eat, she best NOT growl. GOOD JOB! Do this few times, and then you will think you are all set.

You are going to teach her lots. Some she will even master. And THEN . . . your beautifully trained baby girl is going to hit the teens years and rebel; you will feel you have to start all over again! Just stick with your training, you are doing great.

She isn't a teen yet, she is still just learning. I'm just pointing out, you will see set backs now and then, for varied reasons. Don't lose heart, just return to consistent training.
