Quick one-week update (with pictures, so stop here if you're a little squeamish): the tail seems to be healing well. There was an incident a couple days ago where she got the wrap off while I was at work and picked at it a little, but she didn't pull any of the stitches out. The stump was pretty red and irritated after that, but it's looking much better now. If everything goes well, she should be able to get the stitches out a week from today. She's on crate rest and leash walks until then, which she isn't overly thrilled about. And a few pictures of it from today - it's definitely looking better, but the fur will take a little while to grow back. Her tail does seem sore, but she's been using it normally, and it shouldn't cause any issues when it's all healed up.
