I've spent my post work day watching videos about how to field dress and skin a hog.
Some of the hog field dressing/skinning videos are good, others not so good.
We shoot and trap a lot of wild hogs: Every hog is given to folks who need the meat.
Field dress and skin the hog while warm. This is the technique we use:
Skinning:
1. Hang the hog by the rear legs with a gambrel.
2. Wearing protective gloves, cut off the head and front feet.
3. Skin out the front shanks.
4. Slit the skin down the entire front and middle of the back.
5. Skin out the rear legs and hams. Remove the testicles, if present.
6. Using big skinning pliers pull the skin off the hog, using a knife as required.
Field dressing:
1. Cut the poop chute loose from under the tail.
2. Slit the carcass down the front all the way through the ribs.
3. Remove the bladder: Do not burst the bladder.
4. Remove the poop chute.
5. Using a knife as required remove all internal organs,
letting them hang down in front.
6. Cut out the lungs and heart and remove all internal organs.
7. Remove the breathing passage and and throat (goozle).
8. Wash out the carcass as required.
Takes me about 25 minutes to skin and field dress a hog.
