It doesn't hurt that Steve is a confirmed lover of horses - and River knew that!
No more turning the other way when she thinks she's going to get caught - she's actually getting a little pushy, so it's time to teach her that I have a bubble around me that she can respect and ask to come within.
After her run, I took her out back to meet the critters - Asston Martin the mini donkey, Rose Royce the mini horse, and all the goats. I thought she might be alarmed, but, No! She thought they were great. They kinda liked her, as well!
