I would do some trial training with her. Place a long leash on her, and have someone come in from the other side, and as she darts, say NO! in a very stern manner, and place her on time out. Then keep doing it and doing it, daily, for weeks if you have to, until she doesn't dart, then you praise the crap out of her and give her the best treat ever. I know this sounds easier than it will be but it might be worth a shot. |
