Looks like she cut the top and maybe it got infected because the whole foot and a bit up the leg was swollen. All I could think of doing was dipping it a few times in a solution of water and Thieves essential oil and within little time she was walking on it again, and this morning I see the swelling is pretty much gone. I only see a big circle around the cut that looks sealed. It's full of clear liquid like a boil maybe? I will keep on watch on it and see what else I can do to help it along.
