Norwegian Fjords definitely take some firm handling. They can be very headstrong. My riding instructor/trainer had me on one over the winter, as my usual lesson horse (until my mare foaled and the foal was weaned) becomes a complete mental case in the winter. He was headstrong until he got settled into proper riding (he is usually a theraputic riding horse) with me and my dressage trainer. He still had his moments of pig-headedness, but after a few weeks, he started responding to the leg and seat well. Find someone who has experience with the Fjords if you can. They are definitely not like most other horses.
