I have tried several Puppy Pads and OUT! is out in my book. It does not absorb and I am having to wash my indoor dog's paws almost every time she uses the bathroom. The urine spreads across instead of being absorbed in the spot she uses. She makes little urine paw tracks across the pad. The last two packs I have tried, the cotton is so thin that in spots there is no cotton. Nothing has compared to Blue Ribbon Puppy Pads thus far. I hope that WalMart and other stores will bring back Blue Ribbon.
