Lost vibrant blue dog collar with brass name tag engraved 'Rex' near Chippewa Trail, Northern WI.

I lost my dog's collar while hiking in Northern WI near the Chippewa Trail. The collar is a vibrant blue color and has a small brass name tag attached with my dog's name, Rex, engraved on it. I'm really hoping to find it because Rex is my best buddy, and it would mean a lot to get his collar back.
