Every dog, mainly German Shepherds, have liked to get as muddy as possible, usually in a smelly swampy mud puddle, so there has been no chance of them going anywhere but in their assigned, easily washable bed.
Growing up, we had a very sweet King Charles who hated dirt and wouldn't go out in the rain etc.
She would try to get in the bath with you and wanted drying with a hair dryer, so she snuggled with one of us, wether in bed or on the couch.
