In the end, it is necessary for Saints to adjust and acclimatize themselves to living outside in cold weather. In the northernmost state of Alaska, and other climates of extreme cold, Saints live outside all year long without ill effects. But you can't expect your Saint to stay inside during the Fall season and then ask him to suddenly sleep outside in January. He must have time to gradually get used to the decreasing temperatures and have time to grow a suitable winter coat. Although Saints are people oriented dogs, many live outside in the harshest of conditions.
Water buckets freeze solid.
A slight wind chills us to the bone at minus 40 degrees. Outside dogs are grateful for a well sized warm and cozy dog house to retreat to when they can't come inside. The doghouse must be big enough for your Saint to lie down in and to turn around in, but not too big. He must be able to warm it up with his own body heat. The new Igloos are okay, but far from ideal.
