if you didn't split it and remove the bone,you best bet it trash it and hunt for another fox.it will always be bad. the hair will fall out because it has spoiled meat inside.

always pull the bome then fill it with salt.you can pull the bone by,not cutting it off the fox,just cut around the tail only the skin. then take two big nails and put one oneach side of the tail and put the tail between you fingers and pull toward the tip and the skin should slip right off.
