It's the rain and ice that gets us more than the cold. Sam has a poor coat and even with a raincoat he can get pretty soaked and cold if the rain is heavy/chilly enough, especially since he's on the smaller side. And the ice is just dang unsafe. We're prepared this year with lots of enrichment games, new fitness equipment, and a beginner scentwork DVD, but nothing really replaces a good hike. We try to get him out as often as possible when the weather is safe and enjoyable for him/us.
