I don't think it's a photoshop job. I think this mule just went ape sh*t when they put the dead lion in front of it, and they "just happend" to have the camera ready?? Pretty cool pics, I don't know why you would want the hide torn up or you would want to scare the crap out of a mule on a hill side.
I have never hunted lion with hounds, but it seems the dogs would be right in the middle of the fight. Maybe they know the lion is dead and don't mess with a pissed mule.
It will be interesting to hear some houndsmen's take on these pics.
