I'm dealing with this right now too. It's been really wet here and not our normal December in Michigan. I caught my Princess limping yesterday. I examined her and found bumblefoot 😪. I did my best cleaning it out, and I put a fresh bandage on her everyday after giving her a soak in Epsom salt. She is still limping. How long for it to start healing? And what are some signs that something else needs to be done? I took a pic of her foot today if that would help?
You can look at my post on how I treated bumble foot without surgery. It took several months in my hen's case. It was bad and I finally had to take her to the vet (since I was already going with a cat). I retrospect I would not change the bandage daily unless it got wet.
Sometimes less is more. Good luck
