I'm glad that you are there to give advice, and help out where you can, and kudos to them for being willing to listen to you, and take your advice instead of putting on airs that they know what they are doing, and you don't, so no advice thank you. He seems like a sweet natured horse, has a good eye, and I agree that he looks like a strawberry roan, if you look at his face, and the coloring right next to the white which is definitely darker than a palomino, even a dark one, would have. By two years old, he should have dropped, so I would check on it when you go out, because sometimes I know they aren't easily felt, and you can think that there's nothing there when there is. Not being experienced horse people, they may have just missed it, or not even felt around, and just assumed that because they aren't obvious, that he hasn't dropped. Maybe you could go to a tack store with them, and show them what type of bit they should get, as well as a better fitting saddle pad, and make sure that they don't end up with something else they shouldn't use on the horse. He's a cute horse, and I think that he'll turn into a very nice riding horse, if he keeps his really sweet disposition.
