Kell - 2 ideas.
First of all - you might get one of those halter type things to help with the pulling? Or, if you're not opposed to them, a pinch collar just for training her not to pull. A lot of people think they are cruel, but used correctly they will teach the dog very quickly how to walk on a leash and then you can wean them off to a regular training collar.
Two - you will need to NOT have that be your 'running' workouts for awhile. Your runs will be separate from your trips with the dog. Take the dog out with you daily, but these trips have to be focused training sessions for the dog, teaching her what is and is not acceptable, as well as giving HER exercise, at first. You can use this time to simultaneously get the dog more exercise and time with you, as well as teaching her how to behave properly on the leash, especially while you are jogging. Keep the training sessions short - just 10-15 minutes at first, or even less. Give her a short (5 minutes or so) exercise portion to start with, then do some training with her (this is the 10-15 minutes portion) on leash work and basic obedience (sit and stay are critical commands, at least) and finish up with another exercise and play portion. Make it all very positive, use plenty of verbal rewards as well as even food rewards, and before you know it she will be reminding you when it's time for her training! Once she can handle behaving properly at a run on the leash, then you can begin serious run conditioning for her.
And I do agree - do check with the vet on how old she should be before you start serious run mileage with her, though I'm fairly sure that would be a breed which would do great running with you.
It may take quite some time before she's a real running companion for you, but the time spent will be well worth it.
