Charlie the ranch dog

When Charlie wakes up to a world covered in snow he can't wait to get outside and see what's going on around the ranch. He even takes a break from patrol duty to take a fun sled ride with Walter and Sister down the snowy slopes--whee! One ride is enough fun for Charlie but Walter can't wait to go again and again. That is until Walter goes missing! It's up to Charlie to take control of the situation and bring his buddy back before anything bad happens to Walter!
