Charm kiting animals as a druid

[shams]

I love using this method, but I know I'm doing it wrong. At the risk of showing how much of a noob I still am, here are a few questions I have:

1. How do I break charm on an animal when I'm ready to kill it or just decided I don't like it anymore?

2. Is there a way to debuff an animal on my own if say, it broke charm and I had to root snare it in order to charm it again?

3. What's your animal charm kiting method?

Thanks!
