A mare is a female horse over the age of three.
Mares are often admired for their intelligence, focus, and maternal instincts. In both P.R.E. and C.D.E. breeding programs, top-quality mares play a crucial role in preserving bloodlines and improving athletic potential.

A stallion is an adult male horse that has not been castrated — meaning he retains full reproductive ability and typical masculine traits.
Stallions are known for their power, charisma, and presence, making them highly valued for both breeding and competition.
In P.R.E. and Lusitano breeds, stallions are often selected for their conformation, movement, and temperament before entering stud.

A gelding is a castrated male horse, unable to reproduce.
Because of their lower hormone levels, geldings are typically calmer, more consistent, and easier to handle — especially in training or sport environments.
They are often preferred for C.D.E. competition horses or riders seeking focus and stability.
