The cartoon on the front of the beige one was inspired by a horse called Ms Jones, who hated being tied to anything. Caroline met her at Flag Is Up Farms the home of Monty Roberts and spent four years with her. Fergus embodies the stubborn versus strong concept. It is important to remember when working with horses that when in panic they will go into flight mode, or fight mode or freeze mode. All these states of high adrenaline are very dangerous for the handler and so it is preferable to introduce horses to objects carefully and calmly.
The text on the drawing is “I’m not stubborn, I’m strong-willed!”
