house breaking a small pup, books?

 My step daughter ( age 26,  in England) got a 10 wk old Shih-tzu (from a notorious puppy mill AAARRRGH!) and has no experience or knowledge re basic training.  I talked to her about how I've done house training but of course Bugsy was massive by the time he was with us at 12 - 14 wks old so he could go through the night easy.

Anyway any particulars you can offer about house training such a small dog and if you know of a book or two to recommend on basic training let me know.

DH & I are disappointed that she got it from such a place but want to help her educate herself so she can do the best she can from here on out.
