Most tribes had their own word for horse.
Check by tribe.
Here are a few I have found:
nektosha from the potawatemi
punokomita from the piegan
soquili from the cherokee
kava .... tribe name not available
While all the Plains tribes had terms meaning "horse" the idea of a "small horse" is very strange - perhaps you mean a young horse, colt or foal. Wild mustangs, as caught and tamed by the tribes, are generally all the same size, what today might be termed a pony. But the word for horse was still used, not "small horse".
Just a few native American terms meaning horse are:
Blackfoot.....................ponokaomitaa (elk-dog)
Cheyenne....................mo'ehe-no'ha (domesticated elk)
Arapaho......................woxhoox
Assiniboin....................shugataga (big dog)
Lakota.........................shunkawakan (sacred dog) or tashunke
Crow...........................iichiili (elk)
Hidatsa........................itsuasuka, itasuka, itsuwushka
Mandan.......................ompah-meneda (elk dog)
Shoshone.....................bungu
Comanche....................puuku
Pawnee........................arusa
Arikara (Sanish)............xaawaarúxti'
the aboriginal word for horse is i think papat rendsa
also Yarraman is very common and Jarrang, two different dialects.
in lakota, the word is sunka wakan (pronounced shoonka wahkan) with the k in wakan being gutteral
There are MORE THAN 700 Native American languages. Pick a few.
You'll need to be more specific about which Native American language you mean as there is a multitude of different Native American languages.

by horse
The Sioux traveled by horse and they walked.
The leaders of the Sioux tribe were Sitting Bull and Crazy Horse. your welcome (:
A mustang or feral horse is shungwatogla or shungnuni
Crazy Horse was an American Indian leader of the Oglala Lakota or the Oglala Sioux, one of the seven sub-tribes of the Lakota people.
Sitting Bull/Crazy Horse
Crazy Horse was Oglala Sioux, also known as Dakota / Lakota. He is famous among the Sioux and the White immigrants (Americans) as well.
Sioux leaders were Red Cloud, Crazy Horse and Sitting Bull
Crazy Horse and his people, the Oglala Sioux had no choice but to surrender. In May of 1877 he surrendered to General George Cook at Fort Sheridan.
There is no such word in any of the Sioux dialects, so it has no meaning.
