What do we call a female horse?

A female horse is called a mare. If she is a young horse still it's called a filly. A male horse is called a stallion and as a foal it is called a colt. If the boy horse has been cut (unable to breed) it is called a gelding. A foals father is called the sire and a foal's mother is called the dam. Blessings, Angela
