If she is pulling on the prong collar, she is getting no correction. Next time you use it as soon as she steps in front of you give one hard pop and then immediately release the pressure. Serena hardly reacts to the pinch because of her drive. You have to give the correction like you mean it, but then immediately release the pressure. Is she going to formal training with a professional trainer? You've talked about going to schutzhund training, is this happening. Rottie training is not easy to self teach. I tried and failed. With advice from a trainer we have had much better results. We now train with a professional experienced trainer EVERY WEEK. It has become loads of fun for both me and Serena. I used to be uptight and nervous when training and now I don't care if people see Serena and I having a party when she gets something right. Make it fun but be firm at the same time if that makes sense.
