It's been my experience that when all the pus isn't removed, it comes back, so you'll know soon enough. As for draining, again, they're different, so they don't drain the way you're used to seeing in the other animals you have.I couldn't find anything that specifically states blood thinner for Rimadyl (or maybe I'm not using correct terminolgy) but she hasn't had anything since this morning since it's only once a day. Thank you for those anatomy photos!!! I was trying to find exactly what you posted and I kept coming up with images of cooked legs which was clearly not going to help me lol. I was able to remove the scab with the lovely thick backing and keep the bleeding fairly controlled while doing so. I think I got it all but it wasn't an easy area to really see clearly even with flushing and moving things around. Hopefully it still helps. At least it's open so it can drain freely now. Thank you again, those pics were exactly what I was trying to find.
Glad you were able to get it out!
