Our real grass training pads are all-natural, making them completely safe to use within the home. Dogs instinctively want to go on real grass, so training is easy. The living grass absorbs liquids and controls odors naturally, turning puppy potty training into a cleaner, more hassle-free process than ever. There is no cleaning or maintenance needed because the entire unit is fully disposable. With our continuous Fresh Patch delivery service, all you have to do is replace your discarded unit with a new one as soon as it arrives at your doorstep!
