We own 2 weims and while we are working, they are always outsite (summer and winter). They are used to this since they were little and both like it a lot. I even tried once to keep our male inside, when it was bad weather outside (the time I owned just one), but he was very stressy when I came home. You could see he was not happy with this change... They have a luxury place to sleep in, into our garage and sleep most of the time while we are not at home... Once we are comming back home, they greet us with no ending... Of course, they always stay with the family when we are inside.
