I was cleaning Coraline's nails tonight (it has only been a couple days since the last time I did it), and her pinky claw on the front was especially cruddy. She started freaking out when I cleaned away the crud, and then it started bleeding, but I can't really tell what's wrong with it. Has anyone had this happen before? I'm planning to take her to the vet in the a.m. to get it checked out. Is that the right thing to do?
