I have the same problem, and bought distaste, i think it was, but it just gives her diarrhea. great!!!
your suppossed to clean it up right away, or if I see her do it I yell so she definately knows better.
Trainer told us to take her out on leash only to go potty so she had no control where she went and we could remove her right away, but since my 11 year old never complied with that rule, it never really happened.
she has gotten much better about it and it only happens if she is not watched wich is rarely!
