Mine is getting better at being cross-trained."
She will pee on the pad or outside on command. So, if I take her out before she has a chance to use the pad she will go when I say, "Go potty." She will usually poop outside, but never because I tell her, and sometimes she holds it until she gets inside - and never on a pad. oh yeah, and she does whine at night when she needs to go out.
We are cross-training her because we live in perfect weather SoCal. We visit our family in very cold, snowy weather on both winter holidays and do not expect her to understand what this very high, cold wet stuff is after usually being in nice weather - and never snow!
So we are hoping this works when we take her to Grandma's house this Thanksgiving for the first time.
