Sway back vs no topline?

I really have no idea to tell if a horse has a topline or not...and usually if they don't have a top line I just say they are sway back.

Can someone tell me the difference between the two (appearnce wise) and maybe some pictures? Thanks

There are pics on this site that are helpful.

That helps...thanks palogal
It mentioned in the artical that some horses naturally hold their head up high, low, etc...how can I tell that my horse does?

When you sit on him, what does he do? If you were leading him on a loose lead where would his head be?

It's hard to say with me on his back but it appears as if
For a walk his head is level to his withers...maybe a tiny bit lower...head not on vertical
Trot, up higher, but not up in the air
Canter...up high lol

He gets frisky when he does anything past a walk...so I think that is playing a part on it

I'd say he's pretty normal if he's not kissing the clouds or his own knees

I know because he still kind has no topline so I wasn't sure if it was just no topline or a sway back. From what everone said it isn't a sway back so I'm taking no topline..
What do you think?

I'd say no topline. If he's swayback and you put a square western pad on him with a saddle, the pad will dig into his hips. He looks like he just needs muscling. Some lunging in sidereins would help.

not using side-reins...I'm anti- any mechanical device. IMO they don't work that well. The saddle fits fine and no digging into his hips.
What other ways can I help build up his topline? I know some tummy lifts are "supposed" to help, but I'd also heard that they don't.

Here's a picture of him when I first bougth him (yes excuse the chubbyness lol)
This his topline was better then? Worse? The same?
