I have Mud River Dog Products kennel pads. $20-26 pending size I think. I use to use $3 bath towels from Wally World (which would be shredded in a week) but after hearing horror stories on HPA and beyond of dogs in emergency surgery to un-obstruct bowels filled with fabric, I switched over. They take a beating, you'll hear the sound of their nails scratching the nylon fabric trying to get a snag and a foothold to work with and rip it apart, they haven't. They routinely get coated with woodcock cover gunk but they clean up nice, I put an 1/8 cup of laundry detergent on them and rub it in good with hot water, rinse, work some K.O.E into it and rinse again... good as new. They're down side is taking about two days to dry completely inside and out. I've got a rotation of four right now with a pup that seems to have an intense desire to pee somewhere between 2-4am, have not figured it out yet.
