Nice Horse! I agree with the last post, she could use some muscling up in the rear. Don't let her small size scare you, pasos are very strong and sure footed little horses. Most due well being barefoot as well. I board my Paso at a Paso Farm and all of the horses are barefoot. What you are calling "hot" is her Brio. Pasos turn into different horses when you get on them. They know they have a job to do and are very intune to their riders. If a Paso is trained properly they will react to very little cueing and it is in their blood to move forward. Don't let this scare you, it's part of their breed. These horses are very smart, learn fast and bond with their owners right away. I hope you enjoy your little mare and good luck to the two of you!
