Piddle Patch is the UK's original real grass dog toilet! Train your dog to only relieve themselves on the grass with our natural dog toilet solution Our soil-free dog toilet is grown in a liquid retentive mat, instead of soil, as this ensures no muddy paw prints are tracked into the home and extends the lifespan of the grass. Our grass is grown in the UK, without harsh chemicals or pesticides, and delivered direct to your door. Piddle Patch was featured on BBC Dragons' Den and received offers from 4 out of 5 dragons.
