I will agree with the most recent reply, we trained our dog Nikko (Siberian Husky) male, 2 1/2 years old by cage also. I believe it is the most effective way. Dogs treat the cage more like a den, they don't want to mess in the place they feel safe and secure. We also trained him to stay in the kitchen area, so when he does need to "go", he just stands by the sliding glass door to "go" outside. Works like a charm.

I'm not going to say we didn't have our little "messes" in the beginning.......it just takes some time.

Good luck.
