My 80+ year old house has the original hardwood floors. I watched a friend's female puppy 9 years ago and she had an accident in the dining room; cleaned it up and thought nothing of it again. My two older male dogs ignored it for the most part. Fast forward to COVID and I took in a rescue; needless to say, she found that old spot and made it here own. I tried everything: plastic bags under potty pads, a number of potty pads stuck together, nothing worked from keeping the urine off my floors. Then, I discovered the Pawtect Pads. Game changer. The cost of a few of these is much cheaper than the thousands I was looking to spend on fixing my floors if the problem continued. This grateful Old Home owner appreciates this product.
