Are there any Dahlias, like some sort of hybrid, that does not have to be dug up in the fall? If not, is there anything that can be done to preserve the dahlias through the winter without digging them up?

The general advice for dahlias is to dig and store them over the winter months because they are susceptible to rot if left in the ground and they are susceptible to freezing because they are tender skinned tubers (as opposed to thick skinned bulbs or corms). You can certainly try leaving your dahlias in the ground over the winter months. Wait until frost kills the tops back and then cut off all the dead foliage and remove it from the garden. Cover over the area with a thick mulch such as straw or pine boughs to keep the soil from heaving in the thaw/freeze cycle of early spring. With any luck at all your dahlia tubers will survive and sprout when the weather warms.
