I seem to recall a post from a while ago where someone was dealing with severe potty problems

Her solution was to carry the dog around with her in a vest-harness pretty much all day. The pup only was put down outside - to go potty. This forced the pup to wait - so when it was put down outside it had to, and could go. I thought it was a very creative approach, and was effective

Aside from something like that - limiting the pups territory, keeping to a rigid schedule, and CONSTANT monitoring is the best approach. It sounds like she is confused right now, so it may take some patience until she understands what you want her to do

Question - when you said you "let her out" does she go outside with you on leash, or does she just go outside on her own? If she is going outside on her own, I would put her on a leash and walk her. Do not let her come back inside until she potties - pees and poo.
