I have just adopted a rescue dog. It is the first dog I have had in a long time and I am unsure about what is safe for him in this cold weather. When I walk him he sometimes starts limping and I think it might be because of the cold. When we walk it is for no more then about 10 minutes or so. I don't want him to get frostbitten feet. We live in Northeast Ohio and the temperature has been in the teens and twenties for the last few days.
