Real Horses!

We went to visit "grandma" on the farm. Jake was there, and that other one with the bad attitude too. We ran around and played and then there was a REAL horse!! No foolin' At first I was really unsure, do I sniff it's butt like other dogs do? Nope, too high. Do horses bark? Should I bark and see if it barks back? in the end I gave it a good sniff and then just laid down to observe it for awhile.
