Almost everytime I leave the pasture and am out of the gate my mule puts his ears back and sticks his neck out like he's trying to boss me. Is he showing dominance or is it that doesn't want me to leave him behind? He has never shown any agression towards me, so I wonder what he's telling me.
It sounds like something that female donkeys do when they are cycling. Is it a mare or a john mule?
He's probably saying that he wants fries and a Coke with his meal.
I'd like to see what your writing about. Could you take some photos?
He is talking to you, but in a very low voice that you can’t hear. If he was trying to dominate you he would be braying. I think he wants you to stay. Do you brush him? Brush him everyday, grooming is bonding.
As long as you see no change in attitude when you are working with him, I wouldn't worry about it. I always figure what the equines do when they are "off the clock" is their own business. Even after a lifetime with them, some of their interactions/communication is totally baffling to me.
