Today Marlee was climbing up onto the bed, and I noticed it looked like one of her nails caught on the sheet. I went over and picked it up, and its one of her nails! Except it doesn't look like a full nail, it looks sorta hollow or something, and toward the wider end (what would be by the paw) was split in two. Is this normal? I tried to check all 4 paws to see if she was missing any (esp. the back two, cause thats where I thought it came from) but it looks like they are all there.
