Those who live in high-rise apartments might find it awkward to take their pup down the stairs every time he needs a pee. A puppy potty inside or on the balcony comes in handy, especially in the middle of the night. Even if you have a convenient yard, creating a specified sheltered area for the toilet prevents the place becoming too messy and dog urine killing off a lawn. Various forms of dog toilets exist, with one of the simplest homemade options using artificial grass, such as AstroTurf.
Acquire a large plastic tray. For a very small dog, a cat litter box would just about do, but for most breeds, you’ll need something a lot bigger. Drip trays like those underneath refrigerators and cement mixing trays work, and the larger the better.
Lay a few inches of cat litter mixed with a little baking soda in the tray. The litter absorbs urine after it drips through the grass and the baking soda helps control odors.
Measure the length and width of the tray from the inside edges, and cut a rectangle of AstroTurf to fit snugly.
Lay the grass rectangle over the litter and place the tray in the most convenient toilet spot available, remembering that there may be splashes. If you want the potty on a balcony or another outside location, make sure the spot is sheltered from the elements; otherwise the tray will fill up with water when it rains.
Remove and rinse the grass and replace the litter as required. Depending on the relative size of the dog to the tray, and to a lesser extent where you have placed it, this might be daily or just a couple of times a week.
Wipe out the tray with a mild disinfectant at least once a week.
