i have had the exact same problem with tessa. look up my post called "unhousetraining?". at first i let tessa have the run of the house but started in with the "presents". i have to go and crate her whenever i leave. i hate doing it, but i need to do what is best. since i have done this there has not been a problem. i tried to go back to the free house thing and after a couple of days she is right back to the left "presents" thing.
