A pet bed has a collapsible frame with front and rear side walls and left, and right side walls, and a bottom. The collapsible frame also comprises a base which may be disposed in an interior of the frame to maintain the front and rear side walls and left and right side walls in a spaced-apart relationship when the frame is in an expanded configuration. A cover is formed from a pliant material and may be configured to be releasably attached to the pet bed. The cover attaches in such a way to cover the inward and outward faces of at least one of the front, rear, left and right side walls.
