Little madam :D sounds like she's either very excited to be 'outside' again or 'trying it on', probably a combination of both ;)
For some reason links aren't working :( so I've copied my reply to another post on the same subject.
"The secret is to always be totally unpredictable on a lead walk. As Soon as the dog thinks he knows where you're going and tries to get ahead -CHANGE DIRECTION ! and keep changing direction until the dog realises that he HAS to watch you or get left behind or bumped But don't allow his lead to move away from you - keep your hand glued to your side at all times. Your dog will think this is a good game.
At first it's worth quickly changing direction (always at right angle to your original direction, or back the way you came) every two steps or so, then as the dog starts paying attention to you and keeping to your side you can leave it a bit longer, four or five steps or so and then a little longer until the dog is staying by your side at all times and watching you. The nice thing about this method is that if the dog lapses you only have to change direction a few times to remind him. It makes life much more interesting for the dog too as you become completely unpredictable and he has to keep up! Don't forget to talk to him and praise when he's keeping his eye on you.
This method works amazingly quickly - even on older untrained dogs, I had to look after a 4 year oild mini schnauzer who was completely untrained on the lead, and within 5 minutes he was walking to heel and watching me."
Of course, if she's still 'hormonal' she probably won't want to pay any attention to you until she's back to normal :D after all she needs to find a MAN

Hope this helps :)
