Thanks everyone! This helps a lot:) she's already great with her ground manners, and doesn't flinch when a semi-truck drives by! But I also believe that ground manners is key with any horse, any age, any ect. So I will continue to work on that with her. As for the riding, I will get a vet to check her, and talk to me coach/trainer as well. Because I definitely don't want to regress with her:)!
Thanks again everyone!
