I know I live in south Georgia, but it can still get pretty cold. This morning my car said it was 35 which is darn cold for us southern whimps My question is, I know dobes are pretty intolerant of extreme cold and extreme heat. He's never left outside obviously, but for potty breaks, playtime, and our park walks, I think a coat may be needed. He was out for about 20 minutes this morning going potty (he takes FOREVER to poop) and came in shivering. I also want to continue our morning walks so assume that he would appreciate a coat then too. We don't get snow so what kind of coat would you guys suggest? Also, how do I determine what size since he's growing so darn fast?
