I've heard of people seeing weird hairless critters in the winter time when all the mange parasites should be dead, but no this fella had mange. I snuck up on him with a 12ga in broad daylight...he had to have been nearly blind as well.Predator keeper have u ever heard of a sampsons fox it's a rare genetic mutation that results in lack of or shorter hair in coyotes and foxes, not all hairless canids have mange, just thought u would find it interesting
