She keeps a watchful eye on me
 

When I go out the back door the puppy is always just inside looking up waiting for me to come back, she always runs towards me when I'm going out in the hope she will get to go out too.

She has started responding to my "No" command in general fortunately. Now, her latest trick is if she thinks I'm going to go out the door at all, she runs there ahead of me.

I'm writing this in my sitting room at the moment and she is sitting beside the door outside to the back garden. She gets to go out a good bit but not on leash - what step should I take to eradicate this behaviour?

Thanks.

For starters, I'd ditch the word "no". It's much better to tell her what you DO want her to do than what you DON'T want her to do, so figure out what you'd rather she do instead, and then train that. For example, if the problem is bolting out the door whenever it's opened, you may prefer that she sits politely and waits to be released to go out, so that's what you'd teach her.

How old is she?

10 weeks. Well, I just say no to stop her running out and then I am teaching her to go down and wait until I say come. I don't want her trying to come out everytime though...
