Thanks for all your replies. I'm sorry it got a little heated, I didn't mean for that to happen.
I can actually see both sides of the fence. If the dog prefers to be outside most of the time (and I guess you wouldn't know that if you first get him) then he can be outside. But I wouldn't leave a dog outside that a. didn't want to be, and b. was outside when I wasn't home or sleeping. I'd be afraid he'd get stolen, poisoned, etc.
I really hope that this SCWT WANTS to be outside. But the way he pokes his little nose under the fence, I don't know about that.
Do you think his coat keeps him warm enough?
