About 10 years ago we had a doe that looked just like that one!! We had her and one that had a injured front leg all through rifle season that we kept seeing but we would not shoot. Well on the last day my uncle put a drive on and we both knew that them two would come out! And sure enough they did. I had not taken anything yet so I chose the one with the injured leg! We figured it was a tumor. The one that we seen had it from the throat down to the brisket and it was the size of a basketball! That is the only deer I have ever seen with a tumor like that other than in magazines and the one you posted here!
