Dog doesnt want us going outdoors

Question
I am working with an obedience trainer and having success with most areas.  First of all, my dog is a female boxer and will be 2 years old in June.  Our problem is her trying to get past us and get outside when someone is going outside.  She has actually bitten us on a few occasions when she knows she won't be successful.  If she gets out she will run along a fence to my neighors house and will eventually come home.  She is tricky and darts past you too fast to realize she is going for it.  Any suggestions?

Answer
Jim, I dont understand. If you are working with a true certified trainer, then this is not a question you should need to ask me. Are you treat-training your dog? If so, this is bad. Your trainer should be working on the sit and stay command to teach the dog exactly that. If the dog is sitting and staying..then she obviously will not dart out the door. Good luck
