The other day I noticed Meesha's back nails were bleeding. At first I though she cut herself during our walk but then I could tell it was her nail. It was super short and I haven't cut them. I started to pay closer attention to this and noticed sometimes on walks I can hear her nails scrap on the ground (like when she is bringing her foot nack to the front she doesn't lift it up high enough) but I can't tell if it is her front or back paws this is happening to. The bleeding thing has not happened in a few weeks but I thought it was strange. This ever happen to anyone else or have ideas..
