Thank you for all your responses, i have not been able to get on here since friday!
We have found that his escaping is more from being lonely/bored while we are at work so for the time being we are allowing him and our neighbours dog to hang out in both yards during the day. (My neighbour is happy with this situation for the time being) The neighbours fence on one side is qutie old wooden palings and almost falling apart and he has no interest in jumping or even pushing his way through it!
I think we will extend the top of the fence and posibly do something along the lines of the chicken wire a metre from the fence too.
He did have a temp test at the pound. didnt seem interested in jumping or digging!
Appreciate all your help! :)
