This is actually a trick I taught Greta. I don't think I ever teach another horse this, but Greta is one of the few horses I've met that's not mouthy. If only they could all be this polite! She also picked up on in less than a day, and will do it without any treats, just me asking. Love that pony!
OMG as for that last picture: either I look like Justin Bieber or Justin Bieber looks like a girl. Please God be the latter!
