my pup whined for about a week when i first put him outside. Like they said earlier, don't go out to him cos he'll expect it then. It is hard, my neighbour's where going mental but it's worth it in the end. I put an old jumper, a clock and a radio in to keep him company. Dunno if it helped or if he got pi**ed of with radio 2 and thats why he whined....
