Bahaha, he's great with kids, but once you put and adult up on him, he gets a little more ... spirited, shall we say lol :p
Ouuu, what were momma and daddy's stats? What colour is she? Details! :)
hahaha TB's!! Lol my boy is like that too (only half TB though, other half is Arabian), perfect with kids but put an adult on him and he's reliable 90% of the time, and then there's that 10% where he just explodes. Sometimes that's as small as being slightly too forward, sometimes it's as big as bucking and bolting, and he has reared once with me because I wouldn't let him trot towards home.
Filly's sire is a stallion called Hartley's Spirit, whose bloodline traces back to Northern Dancer through some very well-known stallions. The man himself is known to produce big, solid, dependable foals that mature late. They're usually useless racehorses as 2yo's but pretty handy on the track given time to mature (but I'm not looking for something to race). They've got a reputation among racehorse breakers as being easy to break and wonderful to handle.
Filly's dam, as best I can determine, is a mare called Verity (owner said Veirtry but the studbook has nothing that matches anything close except for verity), from bloodlines I haven't heard of, but through dam of dam there might be some well-known English horses. There are a couple of names that are familiar.
So this girl is quite well-bred. Chestnut with 3 white stockings and a star and stripe, will mature around 16hh, coming 2yo, unbroke and free to a good home. Because she's free I'm going to be very skeptical about her, and will make a point of checking out her feet and joints, but she's not even broke so she's not had any of the wear and tear of racing or racing prep. I figure she has a better chance of being sound than the average TB.
