Our Standard DoggieLawn portable dog potty grass (tray not included) is ideal for dogs under 25 lbs. The indoor pet potty grass is 24 x 16 inches and is hydroponically grown on a farm in California. This item ships from California and is a one time purchase only. For recurring deliveries of our real grass potty pads, go to "Pick Your Plan" and choose your frequency. We recommend purchasing our Standard DoggieLawn tray with this portable grass as a tray is not included.
