Drymate Green Dog Whelping Box LinerThe Drymate Whelping box liner is the ideal solution for your litter of puppies. Liner can be cut to fit whelping box; edges will not unravel and entangle puppies. Patented Zorb-Tech (R) anti-flow technology absorbs and contains liquids from soaking through and provides a clean and sanitary whelping area. This machine-washable mat grips the floor and keeps liner flat and in place. Fabric provides soft, insulated surface for puppies and is durable and puncture resistant. Clean up is a cinch; just machine wash like your other laundry.
