i have a one and 3 months old female yorkie. i trained my dog to potty in the big tray she is doing fine(she will go potty on the tray) if i confine her in the bathroom. but once i let her run around the apartment, she seems lost, (poop on the rug). but the funny thing is she knows where to go pee. she will usually go to the tray and pee. I dont understand what is going on>_<how can i teach her to go poop in the tray???? can some one help please!!!!!!!!
