Abstract: A multi-layer modular pet bed includes a foldable outer layer, a folder inner layer, and an attachment means for securing the layers together in order to form a pet bed. The foldable inner layer has a slightly smaller perimeter than the foldable outer layer such that the foldable inner layer sits just within the foldable outer layer. When ready to wash, a user simply opens and unfolds the foldable outer layer to convert the bed into a throw blanket sized unit for ease in cleaning. Optionally, a protective layer may be added, either on top of the foldable outer layer or encompassing the entire outer layer when the modular pet bed is in its folded configuration. Additional cushioning material may be added to any or all layers, in some embodiments.
