Thanks for all the suggestions.....
He does go for a daily walk.
He has plenty of trees for shade, and if anything, its warmer under ther pergola as it doesnt get the breeze.
He has a large kennel, and lots of blankets, and bones and toys you name it hes got it.
He doesnt do it when I am around, nor when I am awake, its like he knows he shouldnt be doing it, but still does.
I dont thing its a medical problem, as he does the number ones and twos there.
He gets plenty of attention when i come home from work, we play fetch, go for our walk, he gets brushed, and I am in and out all even ing beforeI go to bed, and he gets a bedtime biscuit.
The paddle might work, or a rolled up newspaper, because its like he knows he should not be doing it, but still does, just like when he decides to have a barking fit in the middle of the night. He sees me open the curtain, and he scuttles straight into his kennel, not to be heard from again.
Any other ideas?
