One can find a list of horse breeds on Wikipedia. The main horse breeds are Barb horse, Abtenauer, Abyssinian horse, Akhal-Teke, American-Indian horse, Friesian horse and Irish Draught.

A list of horse breeds would include the abaco barb, the American cream draft, the American quarter horse, and the American paint horse. Also on the list you would find the Arabian, the Russian Budenny, the camargue, and the Caspian. Additional horse breeds are the Cleveland bay, the Clydesdale, the American saddlebred, the Morgan, and the Tennessee walking horse.

I'm unsure on the complete list of horse breeds from Italy, which I am currently researching, but these are the breeds I currently am aware of.

Italian Heavy Draft

Italian Saddle Horse

Italian Trotter

Salerno

San Fratello

Well, I haven't counted them all but i think there are over 300 horse breeds, as there are many rare and unknown breeds which are not included on the Horse Breeds page on Wikipedia, although this is still a good list. I found a website which is new, so, unfortunately incomplete. However, they have listed many horse breeds. Check out the website if you are interested: http://equi-mania.wikidot.com Hope I've helped you answer your question!

There are SO many breeds of horses, that it would be totally impossible to list all of the breeds not on HorseIsle.

If you want to see what breeds ARE on HorseIsle, go to the library in a town such as Earton, and click on "Research Breeds" to see a complete list.
