I got out my plastic stencils and taped them down to the mat. First I traced inside the stencils with a magic marker.
I filled in all the blank spaces with black paint.
It works perfect. As soon as I put it down under his water dish he dropped his ball in the water dish and it splashed all over. This time it landed on the mat.
Next up, one for the kitchen under his food dish and his large water dish. This PUPPY is taking over my house and my life!!!!!
