Many pet owners use porch potties to train dogs, especially puppies, to use synthetic grass to eliminate on. Porch potties can be used indoors or outdoors, and are ideal for people who travel with their dogs and for urban-dwelling dog owners who don't have access to greenery. Many pet-product companies make porch potties, but they can be very expensive. To save money, make your own porch potty with just a few simple materials from a home-improvement store.
Measure the dimensions of the washing-machine drip pan. Then measure and mark these dimensions, minus one inch on each side, on the mesh grating and the synthetic grass.
Cut the metal grating and the synthetic grass to the marked dimensions. Poke holes in the synthetic grass to allow for easy drainage. Puncture the grass every few inches with the tip of a pair of scissors.
Place the mesh grating inside the plastic drip pan. Place the synthetic grass on top of the mesh grating, so that they're evenly aligned within the pan.
Spray the grass with a puppy potty-training-aid spray. This will encourage the dog to eliminate on the grass.
Clean the porch potty by removing the two layers (the grass and the grating), and disposing of the contents of the pan. Wash the pan, the grass and the grating by spraying with a hose. Feces should be removed immediately with a plastic bag or poop scooper. Let the grass drain fully and dry upside-down before reassembling the potty.
