If one is into this type method of curing rearing,
a PLASTIC ball bat works well. It makes a satisfying smack sound, it is
visually big enough to startle, it won't break the horses skull, it won't put
out an eye like a crop end.
PLEASE NOTE:
This post does not advocate, nor condemn hitting
between the ears to stop rearing, it merely suggests an effective and SAFE thing
to use.
