Nothing cuter than a baby Fjord! Nope, nope, nope!
And yes, they're defined as horses now, but technically speaking, any breed that averages under 14.2hh is classified as a pony, and so the Fjord fits in that category. And pretty much any horse incyclopedia/book labels them as ponies.
As they grew un popularity, however, especially in North America, the registries switched it over to the Fjord Horse, because they're so versatile and can be ridden by anyone. They're also quite stockier than most ponies.
Either way, they are a fantastic breed & I agree with some of the above posts - i've never met an ill-tempered Fjord but i've never met one that wasn't stubborn either lol!
