My rescued mare is just being backed at 12 yrs old! She's doing brilliantly and she was mouthed, now ridden, in a loose ring french link. She's fine in it. For anyone who remembers, this is Angel, the same mare that threatened to maim anyone who tried to cut off her hideous, scratty beard! She's now got a low trace clip, ALL her feathers clipped off (she had terrible feather mites) and her beard is GONE. And the best part is that even her softy old mum now knows how to make sure she doesn't lapse back into her old ways. I'm nominating the lady who took her for schooling for sainthood lol! x
Baron goes well in one. He tends to hang on my hands quite a lot on an eggbut but much less in the loose ring. Aswell as the french link I also use a lozenge bit (with a copper lozenge) which I also find good.
