I noticed this sore on Carmens back foot about two weeks ago and just thought that she had scraped it on something outside. I've been keeping an eye on it and today it seems to be larger and is now a little bloody but not bleeding out or anything. It is tender to the touch, isn't scabbed over and she keeps licking at it. Has anyone ever seen anything like this before? Do you think it is just a wound or is it something that I should be worried about? I already have an appt at the vet tomorrow for another grey with a corn and can probably get her in as well. Please tell me what you think, I am so worried right now.
