K&H Pet Products Whelping Rail Safety Kit — for Large Breed Dogs — Great Dane, Mastiff, Rottweiler

K&H's whelping rail kit provides pre-cut, pre-drilled HDPE rails that install along the bottom 4 inches of any whelping box interior, creating the critical 4-inch standoff gap that prevents the dam from accidentally crushing newborn puppies against the wall — a leading cause of early neonatal loss in large breed litters including German Shepherds, Golden Retrievers, and Labrador Retrievers where dam weight can exceed 80 lbs. The rail material matches DuraWhelp and other HDPE whelping boxes for seamless retrofit and is dishwasher-safe at 130°F for post-litter disinfection. The kit includes rails, mounting hardware, and a 6-inch corner connector for four-wall installation in standard 48×36 and 60×48 inch large breed whelping box dimensions. Approved as meeting AKC breeder welfare guidelines.
