I have asked twice about his behaviour recently which has been a lot more demanding and "teenage" . interestingly the more positive approaches suggested have definitely helped. I think we were just becoming more and more confrontational with him. Now , for example, if he gets on the chair I put a treat on the floor and give lots of fuss when he gets off. Today he just jumped off as soon as I asked.I have done the same with getting in and out of the car. Thanks a lot for all the help......I do realise that this is not the end of the road but we are all a lot happier for now!
