With a two-layer foam construction and a water-resistant inner lining, the Dog Crate Mat by PETMAKER is designed with comfort in mind. The orthopedic dog bed for large dogs features a 1.75-inch layer of memory foam at the base and another 1.75-inch-thick layer of high-density foam that can support pets weighing 40-75-pounds, perfect for larger breeds. The removable waterproof inner cover protects the memory foam dog bed from getting wet or soiled if your active pet is a swimmer or enjoys playing in the mud. The removable microsuede outer cover offers superior cuddling comfort, has a water-resistant and non-skid bottom, and is machine washable for convenience.
