Query: Iris Protection Tray

I have a long hair Chihuahua; she is a rescue dog & learning about everything as she had been kept in a crate by a hoarder. She didn't know what to make of the tray at first but is now using it to pee. As a last resort she will poop on it. I am very pleased with the product because she will use it to potty first thing in the am. & last thing at night. I live in the Pacific NW so this is a great help. I ordered two more trays yesterday for other areas of the house. The top rim clips to the bottom & holds the pad on the tray. I haven't had any problems at all. The product does what it claims to do & is very easy to clean.
