I have three lungeing cavesons and none of them fit my arab cross. I can mostly get by with buying cob size in her tack, but for some reason cob lungeing cavesons are still too big. The noseband is too large and the jowl strap is ill-fitting. Can anyone recommend a brand or style that is tried and true? She's 15.2, she has an arab influenced head, not quite as convex and small as a full bred arab. :?
