Problems with a "straight" back?

I was just curious to know ... there's a new horse at my barn, a 12-year old Morgan, who has an extremely straight back. There is hardly a dip in it at all, and the withers are barely visible. Is there any health or riding issues with a horse having a straight back?

Hmmm...
Saddle fitting is def. Going to be an issue for this horse. A flat back means his saddle is going to slide around and not fit accurately. I don't know much about flat backs and back issues, but I would thing that it would cause more stress on the back when working. Especially if the horse is sometype of jumper or dressage horse.

Very true. She's a western horse, and I've always known western saddles to be harder to fit. Hmm ...

My three year old is pretty straight backed, but then again, he is still young and unworked really. I'll have to look at him again tomorrow, I don't think he has a back like a board though.

My horse has a pretty straight back with barely no whither. I havent had anyproblems fitting the saddle (although it does slip around a bit sometimes lol) and I havent had any back problems with him at all!! He is harder to ride bareback cause there is nothing to grip onto! He is just a smooth round barrel lol!! But yea, no heath issues to do with his back at all!!

Ok, thanks guys!
