Ok here is t what I caughe story goes that the animal was killed after getting caught in the fence.. how ever in that pic the animal is still alive..heres how I know..
1: the head is elevated at least a foot or more off the ground yet the neck isn't hanging from the wire its at a more obtuse angle. Leading me to thing that the muscles are holding it off the fence or its pulling against the wire.
2: Blood livitity, after the animals heart stops beating blood instantly start pooling to the lowest points of the body. The mouth of that animal is still flooded with blood and since its the highest point it would be the first to loose color.
3: electric fences are made with low enough voltage that it hurts but don't kill..defeats the purpose if your animals drop dead when they run it to it.
