dog-hating horses and cruppers

[Stephanie Wind <wind@moltech.com>]

On a totally different vein, Cathy mentioned having an Appy mare that hates
dogs. I also have a horse that will attack dogs. Is this normal? How can you
keep your horse from looking more vicious than a Rotweiller when an elderly
woman with her little Fifi goes walking by?

Also, how do you teach a horse to accept a crupper if they don't lunge?
