What a great idea! I would probably use peanut butter, since my Otis loves peanut butter (and it doesn't mess up his digestion). I've done one soak time with him, where I got a microfiber cloth sopping wet with the Epsom salt solution, wrapped it around his foot and put a plastic bag over it and secured it with painter's tape. Then I sat with him and fed him treats for 10 minutes and gave him lots of loves. It actually worked!
