A couple of weeks ago I watched an almost grown fawn do the same thing to a dog. This happened in the middle of a field. I could see the dog bedded down in the grass. I thought at first he was a large skunk. The deer snorted and stomped for about 20 minutes until there was a grunt from up on the hill, the deer then trotted up the hill as fast as it could. It was kinda funny. I think this is also the same deer that I watched grow up. I seen this fawn alone almost every day as I took my walk. I guess if it was never taught to fear other animals. That might explain why I got close up for some great photos.
