Hi, I have a new 6 yr old mare Ella, who is super sweet, she literally lowers her head and stretches it out for me to scratch her head. but she clacks her teeth and fidgets when I groom her body. I'm fairly new, Ella is my second horse and my long time partner, Sophie who I lost to cancer last year, also a mare Never did this. so I'm not sure if this behaviour is because she really really likes it or I am hurting her. She Clacks her teeth and then reaches her head toward me and moves away, sometimes pawing the ground. I've tried cross tieing her, softer brushes and gentler strokes with the same responses. Could it be boredom? How do I stop the pawing and fidgeting? And should I be concerned about the teeth clacking? Thank you in advance for any insight on this.
