The mule hated dogs. I got him to ride in wagon trains. Everybody takes their dogs on the trains. I found out pretty fast that wasn't going to work out. :-)
This is from one of our wagon trains. My daughter is on the big bay horse. I'm in the blue hat on my retired barrel racing Leopard Appaloosa. He was the BEST trail horse. His only problem was that he loved beer and there was a lot of beer on wagon trains. As long as I tied him where he couldn't untie his own rope, we did fine.
My Appaloosa was cinchy too if you got it too tight. He didn't go stupid but he would whip his head around and nip me on the butt. That was his signal that it was enough.
Ah, thanks for posting that beautiful picture. Wish I was there.
