thank you for your help with this he is very well trained as from a pup he has been with a trainer but i feel you might be right as he cant seem to over come this we are going to go out later and try what you said with lead work and see if this works over time as he is very food orientated also have spoken to a behaviour specialist in our area who has offered to come round and have a look at him for us as she said it might be a bit like ocd and will be hard to break.

cant thank you all enough for the help you have given us
