Wolves are prepared differantly then coyote or fox
They are skinned for taxidermy
Don't skin the ears out completely (don't remove the cartilage)
Wolf's are left with cartilage IN for NAFA, you only need to partially skin them and salt them, they are different then coyote/fox
Make sure you cut around the pads on the paws the correct way as well, they stay on too, don't cut them off by mistake
Also it may sound gross, but the anus is left on!
I would hate for anyone to get a lesser grade at auction
Here is the page from the manual read it a couple times to get familiar
