Dog hair on the dress?

Kinda panicking. Took my dress out of the garment bag and plastic to measure the length for undergarments and as I'm putting it back in the bag, I notice black dog hair along the bottom. Not like a crazy amount, and if we're being honest, I can almost guarantee no one would notice- buuut it's making me nervous. It's a huge ballgown so I'm sure dry cleaning would cost a kidney. I'm sure a basic lint roller would work, but I'm really just looking for reassurance here! If that makes sense lol. It's really not a lot and I only noticed because my face was a few feet from the fabric, but have any of you had this happen? I'm going to get alterations at David's Bridal, and I know they steam the dresses afterwards, would that help? Thanks!!
