Maybe talk to her – say you'd like to make her a quilt but know that she has problems with her dog chewing things, and would she like one anyway or would she like you to wait a few years till the dog has outgrown (!) the problem? At least it's a heads up that if you give her one, you don't want to see it chewed, and if she doesn't want to be responsible for keeping the quilt safe, she can say so since you are giving her an out.
