* Breed: Pony breeds vary significantly in size and build. A Shetland pony will be built differently and weigh differently than a Welsh pony, even if they are both 12hh.
* Individual variation: Even within a breed, ponies can have different body types, muscle mass, and bone density.
* Age and Gender: Young ponies are typically lighter than adults, and geldings are often heavier than mares.
* Condition: A pony's weight can be influenced by its diet, exercise level, and overall health. An overweight pony will be heavier than a pony in good condition.
Instead of focusing on an average, it's more helpful to look at a range:
* A 12hh pony in good condition could weigh anywhere from 400 to 600 pounds.
It's always best to consult a veterinarian or experienced horse professional to determine a healthy weight for your individual pony. They can assess your pony's body condition score and help you create a feeding and exercise plan to maintain a healthy weight.
