Your Aunt and Alex are very lucky to have you help them out with training.

Sounds like you have your work cut out for you and that you are well prepared a fun filled training session.

If you have any questions or need any tips on giving the ball or tugging feel free to ask.

As for the running away when the kennel door is open and getting away on walks, the biggest thing to remember is never punish a dog for coming back to you. For example when she does get out and finally comes back nothing but prasie should be given. To encourage coming back have yummy treats, favorite toy, anything she loves to get her to come back and when she does it is the best thing ever, a party happens everytime she comes. Practice coming all the time not just when she gets away. It's important that nobody in the family punishes Alex for coming. I like to think about it this way, if I knew someone was going to yell at me for coming would I go back to them, probaby not.
Good luck
