Stop Killing Horses!!

I watched this youtube video of ex-race horses being shot once and dragged, by their legs, by a tractor for 60m. They are brutally beaten with sticks and the same people cut their necks and after all of this, they get turned into pet food!! Whats the point!! This is all because the poor things weren't fast enough, or they didn't meet a standard by the tiniest bit. This is murder!! I am a horse lover, i always have been, but watching this video doesn't only make me a horse lover...it makes me a determined horse lover!! I will stop this cruelty, but i need your help!! Please please pleeease share this forward. I realy want this petition to go far!!
