I think i know what happened to this fox!
Some one put it on a fur frame and didn't turn it before it got to dry?Then,they cut it to get it off of it and butchered the hide!
Try this: Soak it in salt water. I think it should be about 1 cup per gallon of water. When and if it softens it will need degreased then pickled before tanning. It will take awhile to soften up,don't be in a big hurry!!!!!
