Screen

Hello! So, I own a Dell XPS 15. the glass of the screen has had two large cracks in it for a while now, product of roommate's dog sitting on my laptop while after I left it on the couch to use the restroom, and the other day, my back pack (with my laptop in it) fell of a chair, shattering on side of the glass. I was wondering if I can get the glass replaced, and if so by whom? (preferably by Dell, but doubtful)
