Horse Stamping Hoof

Question
When I was down at my sister's house one of the horses would walk and stamp her hoof. What is she trying to tell me and is it she wants me to get in the pasture with them? I know these horses.

Answer
Hi - NO the horse is most probably NOT telling you to go in the pasture.  

If the horse looks like it is stamping its' hoof, it could be just trying to get a fly off etc....OR - it could be warning you to stay away. Many animals will stamp a foot when giving a warning.

Not seeing the actual way the horse is stamping the foot, it is very hard to tell exactly why it is doing it.
