I copied this from the fur harvesters fur manual I hope it helps.
"The first step in pelting your fur is to brush from the head
to tip of the tail. Remove any dirt or mats as completely
as possible. Do not attempt to cut out mats. Next, lay the
fox on the table and grasp the front paw. Cut from the
paw to the elbow joint in a straight line. The next step is
to cut from the hind leg to the belly side of the vent hole.
Cut from the paw to the vent hole using the natural fur
line (white and red colour of the fur). Cut completely
around the vent. By using your fingers, work around each
leg separating the hide. Place the fox in a skinning gambrel.
By using an adjustable set up, one can raise and lower the
fox to whatever level is required. A good set up helps save
on back pain and increases production.
Using a tail stripper, free the tail from the tail bone. Begin
working the pelt forward toward the front legs. Ensure that
when skinning a male fox that the penis bone is cut out.
When you have worked the pelt all the way down to the
front legs, again use your fingers to pull the pelt free of the
front legs. Using your knife, ring around the front paws
when you have freed them from the pelt.
Pull pelt down toward head. Ensure that your knife is sharp.
Gently pull the pelt forward toward the eyes, again cutting
close to the head. Finally, cut the nose and bottom lip off
the pelt. If pelt is bloody or dirty, wash it in cold water and
mild soap. Remove excess water before boarding."
