Dog owners, this indoor grass pad system is seriously smart for those times when getting outside just isn't possible! The main tray measures 35x23 inches - spacious enough for medium and large breeds to use comfortably. You get two replacement grass pads included, so you can rotate them during cleaning and always have a fresh one ready. The artificial grass feels surprisingly realistic under your dog's paws, encouraging them to use it naturally. The secret is in the drainage system - with 6 times more holes than typical pads, urine flows through quickly to the absorbent pad below, reducing odors significantly. Training is easier since most dogs instinctively understand grass surfaces - just place a few drops of their urine on the pad to help them make the connection. Perfect for apartment living, bad weather days, senior dogs who can't make it outside, or late-night emergencies. The weatherproof design means you can also use it on balconies or patios if needed. The grass pads are soft enough that your dog won't mind stepping on them, and the tray contains everything neatly. Cleaning is straightforward - just rinse the grass pad, replace the absorbent layer, and you're ready for the next use. This system takes the stress out of indoor potty solutions while keeping your home cleaner and fresher between outdoor trips.
