Definitely a terrible thing. Several years ago while hunting our property I was sitting on a hill glassing a cut alfalfa field. After scanning the fence-line once, I decided to scan one more time. As I looked, I watched a doe attempt to hop the fence. She thrust her rear legs backward and got her hoof caught in some tangle up chicken wire fencing from years ago.

I made it over to her and by that time she was worn out from her struggle. It took about five minutes, but I used my leatherman to cut the old wire away. She took off and bedded down about 75 yards away.
