The book I was reading mentioned spreading it by shearing equipment so spreading it with hoof trimmers and hoof knifes makes sense too. I always wipe mine down and dry them after using so they don't rust but if I did not have a closed herd now I seriously would come up with something to dip them in before wiping them down. The goat knee I mentioned did not ooze blood or fluid. Just a tiny bit from being pricked but I could not draw anything out of it. I did not know for sure if it was CAE or even fluid in a joint. The Uva Ursi leaves just took away whatever the problem was. The knee was hard and swollen huge and the goat could not walk. I will pass it along to trim her last just in case and clean off anything she might bleed on really good and give some printed information to the goat's owner about CL and CAE concerns in goat's.
