My horse was recently diagnosed with navicular. I've got eggbar shoes on him and on a low dose of bute. He's not lame with this treatment. My question is about my saddle. I have a wonderful Crates reining saddle to trailride in but it weighs 32 lbs. Is this too heavy for a horse with navicular? Does extra weight make it more difficult for them? I've tried to google this question but I haven't found any answers. So thought I'd ask here.
