I agree, Aly described training perfectly. The only thing I have to add is to beware of the smart dog. When we weref irst crate training Sadie, we used boxes to reduce the size of the crate. Smart girlshe was, she figured out how to get on top of the boxes and do her business out the back side of the crate!! Made her own little 2nd story bathroom! We then bought a divider made by the same company as the crate, and that worked much better
