My rabbit's nails ended up getting really long because I moved and lost the nail clippers. Then I lost my job and my dog had a medical emergency so it just slipped my mind. He stopped eating so I took him to the vet and they clipped his nails for me. I did notice that one of the nails is upside down with the underside pointing up. Is there a way to fix it or is it permanent? I feel terrible that I might've seriously injured him because I'm too scatter-brained.
