Saw this on another forum...
If you live in north eastern kansas and north western missouri be on the lookout for tail thieves. Yesterday at my barn at an ARMY POST 3 horses got their tails chopped off in broad daylight (10am-noonish). We don't know who did it. The horses were in a paddock on the far side of the barn where no one looks unless you walk over there. There have been other reports of this happening all over and it's even been on the news.
A friend of mine in Canada, also lost her Gypsy Horse's tail to thieves in the night.
