Minky on one side, and nubby fleece on the other, these are the blankets we use for all of our mommies and babies. We send each puppy home with one, and they LOVE them. They are just the right size for putting in a crate, and for dogs to drag around with them from cozy spot to cozy spot. When layered, they are as cushy as a dog bed, but much easier to pop in the wash and dry.
