If you look at her underside, you may see her udder.
If her tail is lifted, you will see that she has two openings: the anus and the vulva.
The vulva is part of the birth canal.
Young horses: Fillies, which are young female horses, are not significantly sexually different than adult mares.
How do you tell if a horse is a male or female?
A broodmare is a mare used for breeding. A horse’s female parent is known as its dam. An uncastrated adult male horse is called a stallion and a castrated male is a gelding. Occasionally, the term “horse” is used to designate only a male horse.
What is a male horse called and what is a female?
The term “colt” only describes young male horses and is not to be confused with foal, which is a horse of either sex less than one year of age. A young female horse is called a filly, and a mare once she is an adult animal.
How can you tell the difference between a gelding and a stallion?
A male horse is born as a Colt. When he’s three years old he’s called a Stallion even though he may be able to breed much sooner. If he is gelded (has his testicals surgically removed in an operation called castration) he’s known as a Gelding and is unable to breed.
Can you ride a female horse?
A female horse is called a mare. Most mares can make fine riding horses. To the contrary, if they’re managed and handled well, stallions can become excellent, responsive riding partners that take very good care of their human — but they do require a high degree of skill and awareness in a trainer and a rider.
