Thanks to a revolutionary process, our sod farm can now grow a superior grass product in a soil-less medium. This sod is cleaner and much more absorbent than ordinary grass sod. there is no need for a drainage system, because there will be no smelly urine standing anywhere to drain.
We suggest replacing your dog grass once a month for most medium dogs. Many people go much longer before changing the pet grass. You will have to make your replacement decision based on how many pets/dogs are using the Patio Potty and whether it is indoors or outside.
