I have had this same thing happen - hitting a doe in the shoulder that is. In fact, it was the only time I ever lost a deer. My mistake was not waiting long enough. I gave her 5 hours and then took up the trail. No good, when I realized after about an hour of slowly following blood that got fresher and fresher that I was pushing her. I backed out and looked again all the next day but she must have left Dodge. A wise old hunter I know told me I should have gave her much longer, probably waited overnight, so her leg would stiffen up, etc. Anyway, I wish now that I would have done that and it still makes me a little sick to my stomach. At least the coyotes got to eat I guess. Good luck. I hope you find her and just wouldn't push it when looking for her.
