Several studies have been done concerning the correlation between the lack of spots
in Appaloosa's and night blindness. This can be a very important concern for owners since they may not realize their
horse cannot see at night. The condition is named congenital stationary night blindness (CSNB).
Appaloosas are wonderful, sturdy, intelligent horses. Being aware of the condition of night blindness will help
owners provide the proper care for their horses.
HPS is a proponent of horses spending as much time outside as possible, coming in to be fed, and turned back out.
Our horses have a low night light in their barns so they are comfortable to come and go as they wish.
A horse with CSNB should be kept up in a stall at night with hay and water to keep the horse safe. Night blindness
could cause the horse to panic and become seriously injured. A stable owner told HPS memberrs that she realized that
a boarded Appaloosa had night blindness when the horse placed itself in the cneter of the field every evening as night fell
and was still there come early morning. The poor horse had nothing to eat or drink all night long. The problem
was solved when the horse was put in a stall every evening with a low light left on.
Appaloosas with CSNB should not be bred! It will only pass the genital component on to other horses.
