I finally got over my stubborn pride and asked my step dad if I can ride her today, (i've been itching to get on her lol) he laughed at me and said "i was going to ask if you wanted to ride her, but thought i'd see how long it'll take till you give in!" cheeky git!
Any way's I lunged her for a while before hand, she goes both ways with no problems walk, trot and canter.
Then I got on her, it felt so weird being on another horse! Felt like I was cheating on whisks lmao, she done everything I asked, and you can really tell she was used for polo, her canter felt short, like she was preparing for a sudden stop or pivot.
So glad we got her, a horse like that should not be put to sleep.
