Would you allow your horse to...
...put its head down on the trail?
Every time there is a terrain change, my mare likes to stick her nose right to the ground to see what she's walking on. She doesn't stop to do it, but she pulls on the reins and I'm wondering if I should give her her head or half-halt her and get her head back up.
I do ride on a loose rein, so she pretty much has her head anyways, but not normally enough that she can get her head down that far.
I'll bet she'll stop doing it the more experienced she gets, but I'm not sure if it's something I have to stop.
