Dog Potty Spot Made from Sod Squares

We live in Florida and half of the year we are prepping for hurricanes and my dog may have to stay in for hours or even days during bad weather. I went to my local garden center purchased a couple of pieces of fresh sod(yes you can buy pcs! About $2.50 each) I put the sod in a cheap plastic kiddie pool on my back porch and voila! Outside potty inside!
