Lola, our 4 month old border collie has been a delight. She is easy to train and generally 'gets' things quickly. However, when we went to puppy training,one of the first things they taught us was an exercise to discourage 'jumping up' . We did this, and the behavior reduced for a while. Unfortunately we slacked off a bit , doing other things and now she jumps up and everyone all the time, standing sitting, at home, in e park. She has 'got wise' to the exercise and doesn't do it when we 'practice'....
any ideas?
