I think she said that a 12yr old was lightly riding the mare. I'm thinking maybe saddle broke but not trained at all. And, at her age, you would think she'd have been doing something or in a broodmare band.
That's kind of what I think, she should be doing alot more.
Putting it in the ad that a 12 year old is lightly riding her makes it sound like the horse is very good, but then it says that the horse will make a good WP horse, tells me she's only in an arena probably walking around. Take her out of the arena and she'd probably wig out and the 12 year old probably doesn't ride her.
It's very possible that this is a very dishonest ad. If I was looking for a horse and read an ad like that, I wouln't even bother to go look.
