My ex was a vet. When skunks hit dogs she used dawn and peroxide. It worked amazingly well. I have been using dawn on all of my hunting clothes for years with great luck. It actually breaks down the oils in the fabric....so on some wool you'll need to move quickly to not smoke the natural oils.
I use Charlie's Soap Laundry Powder. Fill up my bath tub and agitate the clothes by hand and let them soak. It's worked to get the funk out of wool clothes I have bought off of Ebay.
I’ve brought my share of used shrunken smelly wool shirts / jackets. Some smell like it was stored in a damp musky/ moldy basement for decades. Others smell like their dog had been sleeping on it.
And it’s not just wool. once brought a hunting jacket made of polyester. It smelled like dog urine (had dog hair all over it.) wouldn’t surprise me that was the reason the seller sold it.
Try dry baking soda on it for 24hrs then hand wash it gently in water & vinger. Hang/ lay flat on a towel to dry.
Follow the cleaning instructions on the label.
Unless the label say it’s ok to wash in a machine, I would not wash 100% wool in a washer machine. I made that mistake once, and I was shocked at how much it shrunk.
Unless you like the smell of febreze, I would not use febreze on hunting clothes. It has strong scent.
I brought a used hunting shirt that smelled like febreze (flowery scent). Had to wash it several times to get it out.
