You are correct it was iodine & sugar wrapped with vet wrap & duct tape over it to hold it on.. For the bumbles, you might try what someone on another thread did, mix sugar and ... oh rats, I'll have to go look and come back, think it was iodine? Anyway, she mixed into a paste, put on the bumble, and wrapped with vetwrap or duct tape, and never had to do surgery. WAY simpler. I'll look it up and post later. Just my random thoughts on how you might deal with this.
