The Petnap Whelping Box comes with a set of 3 essential puppy rails & is constructed from robust corrugated cardboard.
Comes with a further piece of wax lined cardboard to help prolong the life of the base of the whelping box.
Disposable whelping boxes are often preferred as they are recyclable & avoid cross contamination.
Whelping boxes should be purchased and in place at least 2 weeks before your bitches due date - this allows them time to adjust to being in the box instead of their usual favourite bed.
