Breaking and Training the Driving Horse by Doris L Ganton (1984, Paperback, Revised)

81 pgs, 40 illustrations, many b/w photos.
A good basic starter book for training the driving horse. Covers the most common areas related to starting a horse in harness. Describes the proper names of the harness and carriage parts, which makes for a handy reference when dealing with harness makers and carriage makers.
Sweet: nicely done illustrations, concise overview, excellent descriptions of vehicles and harness, as well as a bits page. Low priced
Not so sweet: Somewhat dated (20+ years publication) Geared more towards a show ring than the average pleasure driver. Does not address problems that can occur with certain horses.
