We have a big dog, Maddie is an 86 pound white lab and she loves our bed to nap on even though she isn't supposed to be in there. She would destroy a quilt easily just from her weight and nails. I have an older quilt that I will put on the bed with the back up so she can get on, but usually I just keep the door shut. I would not put a nice/new quilt for her to sleep on as it wouldn't last.
