We moved to a newly built house and there is no grass yet. Our small dog just won’t seem to go potty on the dirt but does when we walk by neighbors yards where there is grass.We bought the 4 x 6 ft piece and it actually does look realistic but smells lie the rubber backing (until it off-gasses some more).The backside has some rows of holes to drain. Yesterday the dog looked at it, ran down and peed on it. Success!I bought it because she peed on the carpet a couple of days before, darn it.I sprayed it off with the hose later, likely should do that every day or 2.
