These are wonderful for travel, at home and to use in your dog's crate. These mats are made in seven sizes and in two different fabrics-fleece or micro fiber. Their non-skid backing works great on hardwood floors. The mats are crate pan sizes and have small elastic straps on each corner for securing around the tray of the crate. The SUV size can be used in a whelping box or thrown over the couch. These mats are machine wash and dry.
