Chin bedding mistake

So we realized the past week our chins bedding has been plain pine not KD mistake order from amazon. Now she seems to be not eating well and sneezing some. I swapped out the bedding for a fleece blanket until I can run to the pet store for aspen (45 min drive). Will she recover now that we have fixed the issue? I have called our vet locally but I would need to travel even farther for a small animal vet (90 mins). She is about 12 years old. Thanks
