This is a MIRACLE!!! I am serious! I adopt elderly dogs and I expect accidents. I just adopted Angel who someone just abandoned in the forest. Almost every morning I would find one of her accidents. No matter how many times I would take her out poor baby she just couldn’t hold it. Since this product was “money back “ and I was desperate why not. I really didn’t expect much. But I swear to you it worked!!!! This is a miracle! I only bought the smallest amount but I just bought two gallons today. I’m sooo happy!
