OH! There is actually a type of 'doggie' litter box now. I know of breeders that use this stuff to help housebreak small breed pups before they go to their new homes and pup buyers rave about how well started the puppies are when they get them (they learn to go outdoors when the box is moved out there by the breeder or whatever system used). I know of one Anatolian breeder that raises her dogs as house dogs and she recently bred her first litter in about a decade. She said she liked the convenience of this box because she didn't have other arrangements for the pups to go outside sometimes. I don't personally have an opinion/experience with it.

Here's another article using different locally available materials.

All that said housebreaking an adult or near adult dog should generally use the same techniques normally used with puppies. Here's an article called: Housebreaking the Second Time Around one of our forum library has on housebreaking rescues and other adult dogs.
