Well for the first while (3 months) just a pen, no shelter (winter in Canada,

) but then about a month ago the built a particle board 3 sided box with a roof, that did not proctect them from the wind at all sides. Then I guess the human society steped in. Then they put a forth side on the box with a opening with blue foam on the inside walls. The dogs ripped out the foam and spread it outside in their pen so for 2 1/2 weeks they walked in 3 inches of foam outside and had no where to poop. Finally the crappy owners cleaned it all up but they still leave their dogs to freeze while they live inside their warm brand new house. They do not even let their dogs sleep in their double car garage. Sick sick sick!
