Just want to say that his help was amazing. Yogi is a transformed dog! He has seemingly learnt everything instantly, Like magic. No more jumping up. No more barking to come in. So respectful and responsive. Just the change in our approach, posture, tone of voice, instructions to him and mostly our expectation of how he will behave. He has not jumped up at us at all. He has stopped barking to come in. He steps back to let us all in the house and waits for us to walk through doorways etc. We are so impressed.
