We live in a condo and one of our dogs is a senior tripod, so it’s especially helpful to have this lawn on our balcony when it’s raining out, for late night pee breaks, etc. Our dog is ~30 lbs and I find that if he uses the lawn once to twice a day on average, it lasts for ~two weeks before he starts getting fussy about it. (Our other dog refuses to use it.) I’m not sure if it’s possible, but I would love to see Doggie Lawn’s operations expand to the east coast. Shipping (understandably) takes a long time to get from CA to the opposite coast, so I have to factor that in to my ship dates. So far though I’ve found service to be consistently good and I’m happy with our subscription.
