I'm assuming that you're wanting some general info on what an NSH is like, attitude, abilities, etc.? If so, here it is.
I used to own a pair of NSH mares- sisters. They were my first horses- and I couldn't have asked for better teachers! The girls I had were very friendly, and the most loyal beings I've ever met. Once you win their loyalty, it's yours forever. The older sister was built more like an arabian than a saddle bred- she had a delicate face and was skinny. (Sadly, she passed away a year ago). Now, her sister, who I still own, is more like a Saddlebred- right down to the swayback! She has an EXTREMELY bad swayback! I'm currently looking for a custom pad for her! I use my current mare for dressage, and she's doing very well- these are incredily smart horses!
In my opinion, they are the perfect breed! They're fairly calm and quiet on the ground, but when you ride them and ask for a little bit more spunk, you'll get it! They can be very flashy and showy, with a "look at ME" attitude.
Hope this helps! Enjoy your new girl!
