My friend had a barrel mare that got her tail chewed REAL short by a cow...dumb horse let the cow do it. Well, we had her momma, and they are the same color, tails matched perfectly. We contemplated cutting her mommas tail to extend her tail. Never did it, but we considered it real hard for a while!! I thought it would be dumb though, cause then you'd cut one's tail to fix the others. Her momma wasn't used for anything though, just breeding.
