at petco we were looking down the weewee pad aisle and noticed a yellow post and i read it and it said that dogs smell the urine and know to go there..so we bought it and it worked GREAT! maisy hardly ever went in the grass..were we wanted her to go..she would go before or when we got back inside..well it worked great for about a week and still once in a while but not as well..i think the smell is wearing off..even though it said even if humans can't smell it dogs still can...i recommend it though..since after a week of using it she knows its ok to go there!!!
