We haven't used one, but my sister trained her min pin to use a litter box. It works well for them. One potential problem - when our dogs are around their cousin's litter box, they eat the litter and carry it around the house. We personally use piddle pads. I saw someone else on here who said they used a little box with a piddle pad in it instead of litter. That sounded like a neat idea. Good luck! |
