I thought mine to speak, many videos on YouTube to learn. Once I had that down pack I would tell them by the door before going out speak and give a treat. Then one day my older girl which is 2 1/2 started doing it on her own she had diareah that day. So I got so happy with the good girl good girl. One day my boy started speaking by the door so I did the happy dance for him too. But he still wears a belly band because he is not neutered and I've used him for stud, so he still marks around the house. Then my youngest which is 8 months picked it up in two weeks she was speaking too. So now potty time they start barking by the door. If they play or want something they squeak and whine it's a yorkie thing I guess. Good luck on your training, I'm thinking of installing a doggy door since my yard is fenced in so they can just go out. Btw my boy dosent pee when he has the belly band on but if I take it off instant marking starts.
