I've dealt with horses who "blow up" while you're girthing them up, but Blaze is pretty bad. I know he's doing it, so I just loosely tighten the girth as I'm tacking him up. Then I walk him over to the arena, and tighten again.
It hasn't been a real issue until today, until we finished a canter and I realized how loose my saddle was. Before I'd hopped on, I'd walked him around/attempted to tighten the girth 3 times!
Any other suggestions? I don't want to end up underneath my horse I know one thing is that my girth is too short; I need one that's 2 inches longer.
