I've washed heaps of stuffed toys over the last 6 months. We've been given heaps of them of different sizes and I just threw them in the machine. I did wash them near the end of summer though so they got plenty of time in the heat and in the sun. I have washed some smaller ones during this winter but I dont' think I'd like to wash one that's toooo big and fluffy unless it was a really sunny/dry day.
