After soaking him it seemed like scab really wasn't ready yet to come off - I was really trying to get under and lift it but couldn't get anywhere; felt like I was going to have to cut part of his foot off to get it. However, it was looking more scabby and dark all across the top of the bumble instead of just the middle -is that a good thing? Put iodine & ointment on & wrapped his foot with a shoe and I'll follow your suggestion about when to let him get a swim in without the wrap before treating him every couple days. I couldn't find clear iodine locally so I ordered some a few days ago and until that comes I have been using something on-hand that is clear-ish but tinted. It's a potassium-iodine solution. I don't know if it has done any good but I figured I could try it. I used your salt-to-water ratio this time which was probably about 2-3x stronger than what I was doing before so hopefully that will make more of a difference now.
I'm sorry to hear you had to say goodbye to your father just months ago. I am going to need some extra strength when that day comes for my daddy! He farms corn, wheat, sorghum, sunflowers, alfalfa, milo and cattle. He doesn't do all those crops every year but rotates them. Before he was a farmer he was a Denver police officer for 20-some years, and before that he was a Marine and fought in the Vietnam war. He has incredible stories - both happy and sad - I really wish I could write a book about his life!
