Broke 7 year old pony mare. My 5 year old rides her with help. My 9 year old can ride her by himself with no lead. Shes a very sweet mare only fault is she has 1 eye so she is sensitive on one side but has never ran off or bucked. If she spooks she just stops then will continue on when asked. She isnt a fast pony will only walk and trot ill measure her but I would say close to 30 inches. Has good feet and is current on vaccines and wormer. Will walk through water and over tarps nothing bothers her too much. I have videos of the kids riding her.
