Hard to tell with the body position. It has a sagging belly, but no dip in it's back. It looks more like, from the picture, that there is something wrong with it. It's body positioning looks like it may have some sort of spinal injury. The picture seems to say, "quick, somebody shoot me please." Do you have any other pics of this deer?
Actually, in that picture it was taking a dump. I have another photo I'll show another pic of it later.
