Sondra Baker purchased a puppy last spring. But the suburban Chicago resident rarely takes the canine, an 85-pound Bernese Mountain Dog named Oscar, out for a walk to the park a block away.

Instead, the beast does his business in her condo several times a day — and not on old newspapers laid out on the kitchen floor.

Rather, Oscar, like many other dogs around the country, uses a new pet toilet called the "Pet Loo."
