I have researched past posts on treating ringworm with fluid film, and bacon grease, and the fung all from sullivans but am still wondering what is the best treatment and what is the best way of ridding this stuff? Is the shampoo worth using and what about the pen? Is there anyway to get rid of it completely? We have never had this problem before and unfortunately bought a steer that was housed with others that had it and now our second steer has it to. Any help would be great!! I am not worried about hair right now as we wont be showing them till early may so I am open to all suggestions. Thanks!!
