My dog will not poop in front of anyone. PLEASE HELP fix my mistake!

Hi!

I want to thank you, your "8 weeks to 8 months" video has worked great for my newly adopted 6 month german shephed pup. I saw changes in days with the in-home leash training! I am the first to admit it is me who needs more training then the dog, and that is why I'm coming to you. My dog I working on potty training. I say "working" because she will not poop in front of anyone. I was having problems with her going in the house right when I got her in sneaky places where I couldn't see her. She is not almost there. She hasn't had an accident in the house in a long time and is allowed to sleep out of the crate at night now. We still do leash work in the house to make sure she won't wonder off. But she refuses to poop in front of anyone. We don't have a fenced in yard so she is always on the leash out side because we don't trust her enough if someone with another dog walks by that she would mind us. But anyways she pees no problem but has not pooped once on the leash in over almost a month. The only way she will go outside is if we let her out on our very small fenced in courtyard which I do not want her messing in for that is where I and guests like to sit or stand and chat. I don't want large piles in our nice little courtyard. But the only time she will go is if we let her by her self and since that is the only place fenced in, it is the only place she'll go. I understand now I have started a bad habit of the first time she went outside I was so happy it wasn't in my house I didn't correct her. And I have let her continue to do it for worries she'll hold it until night and go in our room or some sneaky spot in the house again. We have tried taking her out every hour, waiting and waiting for her to not be able to hold it anymore but she always does. then she'll sit and whine at the courtyard door. PLEASE HELP fix my mistake!!!

THANK YOU! Ashley
