Dharma by Border Collie x girl was like that. She used to turf all the bedding out of her beds and lie on the plastic base or on the quarry tiles in the kitchen. Her absolute favourite place though, was to lie in the middle of the garden in the coldest possible weather. I have vivid memories of one particularly snowy winter, just being able to see the tips of her ears above the snow! 
Basildon, I think you're very sensible keeping that set up until he' at least past the teething stage. Our house is tiny, so we only have the kitchen and living room. Pip has free access to the kitchen and garden when we are home and is allowed in the living room as long as either myself or dh are with him, but gets put back in the kitchen if we have to nip upstairs or something. We often leave Lurcherboy asleep in the living room and will do the same for Pip when he's fully mature and grown out of chewing.
We have just had a lovely walk. Which is a surprise, as I now have dd's bug and was totally disorganised, forgetting to take a ball and flinger with me for Lurcherboy, as well as the whistle for recalls. Fortunately we had a couple of frisbees in the car and Pip was hungry enough to return to verbal cues. Then we bumped into some people we knew with their young dog and as we stood chatting Pip decided the dog was nice enough to say a proper hello to.
It was fantastic socialisation for him, as the other dog is friendly, but submissive and in the end they kept just going back to say hello to each other again. He also chose to approach another Shih Tzu type dog and say hello, despite the fact that dh had gone ahead with Lurcherboy - so that was massive. 
He's really coming on now. Still wary, but definitely becoming more and more confident around other dogs and far more willing to interact.
Oh - and we took him to PAH and bought some dreaded pigs' ears while we were out as well. Dd has some sort of sponsored event this week, so I'm going to have to be out for about an hour and a half. I've bought two more big kongs and am going to leave him with extra kongs, a pigs ear and some fish4dogs braids and hope for the best. He can do an hour now, but an hour and a half is pushing it.
How long do pigs' ears generally last other people's pups?
