What is a female horse called?

The term HORSE is mostly used to address the male horse. The general name for a female horse is MARE. A young female horse under the age three is called a FILLY. However, the term FOAL is used to address both the young male and female horse.

While an adult female horse are called MARE. A DAM is the name for a female parent of a horse with known breeding lines. A YEARLING is a young horse either male or female that is between one or two years old. Hope this helps.

The answer to this question should not be fill in the blank. How are people supposed to know that you mean any female horse. When you say female horse people assume you mean an adult one. If you wanted mare and filly you should have specified, better yet, make it multiple choice! Even if someone did say mare and filly, they could type it filly, mare and get it wrong. Someone needs to rethink how they make their quizzes.
