You must be getting frustrated. Have you tried keeping some treats in a bum bag? Leave the zip open a little so she can smell it while you are puting on her harness( it should keep her occupied till you are done). As for the walking maybe lett her sniff a treat and toss it a metre up the road, for her to chase it. make a game of it . then slowly reduce the amount you toss to every ten steps then 20 steps and so on. Hope this helps.
