* Shape: It's rounded, often slightly sloping downwards. The top part of the rump is called the "croup."
* Size: It's large and muscular, as horses need powerful hindquarters for running and jumping.
* Tail: The tail is attached to the rump and is typically long and bushy.
* Hair: The hair on the rump is usually shorter than on the rest of the body, giving it a smooth, streamlined appearance.
* Muscle definition: You can see distinct muscle definition on a horse's rump, especially in well-conditioned horses.
Think of it like this: Imagine a rounded, slightly sloping hill with a big, fluffy brush growing from the top. That's a horse's rump!
Remember, different breeds of horses have different body types and sizes, so there will be some variation in rump appearance.
