I have a pure bred Boxer and I live where it gets cold. It has been below zero at night for the last couple of weeks. He has little to no body fat and gets cold pretty easy. He is not out for extended periods of time. The do make paw socks for the sled dogs, but trying to put these on an adult dog that has not worn them before could be a rodeo. I do dry his paws when he comes in. Oddly he loves the snow and will burrow in it, playing. Again, he gets dried off when he comes in and then he is on his pillow by the fire. dogmom said it, watch them, they will show signs of when they are cold.
