I have a 10 year old Morgan, TB, Percheron cross that I’ve owned for 5 years. I broke her late and she was, and is, a real wild spirit. She’s dominant and can be pushy on the ground but is usually laid back and sweet. She gets more aggressive when I tack her up, and it’s like flipping a switch. She’ll go from calm and standing with one leg cocked to walking into me and spinning in circles. No amount of ground handling can keep her from moving-- she refuses to stand still. I have the same issue when mounting unless she’s distracted.
My first thought was the saddle causing pain and making it a negative association, but I have had both my western and English saddled fitted to her, and use gel and relief pads as a precaution. I never mount from the ground and recently had my vet check her for soreness in the back and came up with nothing.
I’d like to know of exercises I can do with her to resolve the tacking issues first, then the mounting problem (hoping one might help with the other). Has anyone experienced something similar? I feel like I’ve tried everything over the past couple years and it seems to be an escalating issue. When I first broke her she still moved around a lot but didn’t spin. What do yall know?
