I have dogs. Occasionally dogs have accidents. Occasionally we spill a drink on the floor. We had one such incident happen since getting this rug pad and it seems to have worked to keep our hardwood underneath from getting wet. A little pricey but worth it to save floors. I’ll be buying these pads for most of our rooms. It was a little bigger than the rug and we need to trim it down. I haven’t been able to do that yet so I can’t comment on ease of trimming.
