Hi Heather, Adam here with Lennypads. We have sold countless pads to breeders over the years and they work wonders in a whelping box. During delivery they soak up fluids and any blood washes out well with Peroxide. For weeks 1-8, the pads are great for absorbing urine and feces from the puppies.(pads wash up white and bright with bleach or oxi-clean) The top layers wicks away the liquid keeping the puppies dry, comfortable, and clean. Also clean up is easy with the leak-proof vinyl barrier that is built into each pad. As for the reviews online, we have an abundance of positive feedback, but there have been a handful of Amazon customers who did not understand the quantity of pads in each order or was confused when we removed the logos from the facing of our pad. For the most part, customers LOVE Lennypads - this includes everyone from Veterinary Clinics to "at home" users. Heather I hope this helps! You can order pads online at Lennypads.com or always call us at 1-844-PET-PADS. Through Monday you can save 15% at Lennypads.com with coupon code EASTER15. Thank you for your interest and good luck with the pups!
