Have a pretty decent size herd (well really two separate ones that mingle in the middle) here at work. They've been out in the fields every night for the past 3 weeks about 4-430ish when I head home. 2 weeks ago there were 3 6pt and a nice big 8pt....now all antlerless. And another guy go a picture on a trail camera of a big buck that had just two big flat spots where his gear was (probably the reclusive 14pt nobody has seen in person).
I've had my dog out a couple times and went to all the bedding areas close by, nothing. I'm planning to go further out soon after a little melting with the projected 40°F days coming up this weekend.
My dog has never found a real shed, just all the planted ones I leave around.
