My idiot (excuse me) mom clipped them with normal nail clippers when I wasn't looking, and now they're 3x shaper then they were.. it's really hard to hold her, let alone try to file them, should I or should I not?

Also should I put anything on this? It burns really bad to even touch it so i'm hesitant (this was from my pups dew claws) http://i635.photobucket.com/albums/uu74/lovestosmilexo/5214285943_72e2186566_b.jpg
