I have a sport influence bred appie (TB and Arabians thrown in there) x with a foundation bred qh mare.
So far, so good. Though she has not been backed yet. She is really athletic and quick! I have turned her out in the arena to play with others and she's taken jumps several times all on her own just because she seems to like the challenge.
She is in my avatar and you can see pics of her in my horses.
So far she is not nearly as dense as her dam, who was a very solid mare. I never saw her sire. She was sort of a rescue/project. I also think her back is a little long for ideal and she has a short croup. She's also butt high, as she grows she seems to level and then go but high again and then level. So we will see how that turns out! Her feet seem in proportion to her body and are tough as nails.
