I've placed all of my daughters stuffed animals in the washer and dryer with no problem. The only ones I don't do are the ones that make some kind of noise - those get hand washed. Also, you might want to consider once a week placing the animals in the dryer for 15 minutes or so to get mildew and dust mites off of them. The heat from the dryer does the trick!
good luck - M.
