Here's why:
* Space: Miniature horses, while smaller than regular horses, still need ample space to move around and be comfortable. A house is too small for their natural behaviors like grazing, running, and socializing.
* Hygiene: Horses are naturally messy, and their hooves and manure can create a significant mess in a house. They also require regular grooming and cleaning, which can be difficult to manage indoors.
* Health: The confined space and lack of access to fresh air and sunlight could negatively affect their health.
* Destruction: A miniature horse could potentially damage furniture, walls, and other items in a house with their hooves and playful nature.
* Safety: A house environment can be dangerous for a miniature horse, with potential hazards like stairs, sharp corners, and toxic substances.
It's important to provide a safe and spacious outdoor environment for your miniature horse, with a paddock for exercise and grazing, a stable for shelter, and access to fresh water and hay.
