I went through all these options with Stell for her front foot. She absolutely freaked with the e-collar, falling over and banging into things, so I tried to find a bite not but there werent any in our area, so I tried the rolled towel thing, didn't work for a front foot on a pretzel dog.
Finally what worked was a muzzle duct taped, with holes in it, I couldn't find a stool guard in time, and me trying to be home as much as possible because I was nervous leaving her alone like this. I also cut the foot and leg out of about a million pairs of panty hose and would spray them with bitter apple spray, let dry then put them on her and tape up around her knee, I figured they still let air in and the dried bitter apple spray slightly discouraged licking.
It was very stressful so to you
