Curb bit and bridle sizing
I have a 15.3 hand Quarter horse with quite a big head and even bigger muzzle. I am currently using on him a full sized English bridle and 5" eggbutt snaffle bit; everythings fits great. But I have a much harder time when it comes to western tack. All the western bridles we have don't fit him; the browbands and throatlatches are too small. Also our 5" curb bits are too narrow for his mouth. I know that these bridles and bits are the standard size and fit many horses, but not mine. What type of bridle should I look for to fit him? Would a 5 1/2" bit work?
