I purchased these for my incontinent senior dog. She’s a 87 pound lab. These are just barely big enough. I have to use two because she wants to lay her head on it and then her hinny is off the edge and that defeats the purpose. They tend to wad up when she moves around but when she does leak on it, it does an excellent job of absorbing her urine. She even caught the very edge of the blue border once but my floor was still dry. When she missed the edge completely and got urine on my carpet, I flipped the pad over and stepped on the wet spot and it did an excellent job of sopping up her urine from the carpet and my foot stayed dry.
