I used a soft collar for Diggity recently when he had the start of a hotspot on his paw. He didn’t like it during the day, but at night, he just went right to sleep with it on. This is the one I have. Not sure of the size as I had it with my previous dog and had bought it several years ago.

As for spaying, I think you need to do what you feel is right. There are lots of opinions, but at the end of the day, it’s your dog and you make the call.
