I think all of this can be fixed by some good, reliable commands. You should work on her recall. That way, if she gets out she will come back when called anyway.

You could get someone you know to ring the door bell and dont open the door until your dog is sitting down. This way, the dog knows she needs to sit down for the door to be opened. The catch with this is that you need to make sure she is reliable with the sit command and will remmain sitting until the guest is inside.

Again, for this one to work you need her to know sit very very well. Pheobe reminds me of my Grandmas JRT.My Grandma taught her dog (Kipper) to sit when she tells her to. For the first while she kept treats by the door so when the door bell rang she would tell Kipper to sit and give her a treat until the person was in the door.

My friends dog is trained to look out the window when someone comes so he doesn't run out. This will take some two person training. I know she taught her dog to do this by having someone ring the doorbell and telling her dog to "go look out the window" and she ran towards the window. When it reached the window you should praise her ect.

Just make sure you use postivie reinforcement.

These things might not work for your dog, every dog learns differnet.

I hope I explained them well enough
