you can get the piddle pads from some members here on YT, or from
http://www.drsfostersmith.com/produc....cfm?c=3307+32
and you can also get the trays to hold the piddle pads on to make sure the floor does not get wet. (these cost less than $25.)
It is not a good idea to train the dog that the floor is the place to go.
A piddle pad is much easier to clean up after, and less confusing to the dog..
