Where in the world has most horse breeds?

It's difficult to definitively say which country has the *most* horse breeds, as there are many ways to define "breed" and different organizations have varying classifications. However, some countries are known for having a high number of native breeds, often due to their long history of horse breeding and diverse landscapes.

Here are some contenders for the title:

* China: While not widely acknowledged in Western equine circles, China has a remarkably diverse collection of horse breeds, estimated to be over 200. These breeds often vary significantly in size, conformation, and use.

* The United Kingdom: The UK boasts a long history of horse breeding and has developed numerous iconic breeds like the Thoroughbred, Shetland Pony, and Shire Horse.

* Russia: With vast geographic diversity, Russia is home to many native horse breeds, including the Akhal-Teke, Don, and Orlov Trotter.

* Mongolia: Known for its nomadic heritage, Mongolia has several unique breeds including the Mongolian Horse, known for its hardiness and endurance.

Ultimately, the exact answer depends on how "breed" is defined and how many breeds are considered "native" to a country.
