I've seen and heard of these sorta things all too much... It sickens me... I am going to show this video to everyone I know so they can spread the word about it. And I don't mean to sound heartless or cruel, because as much as I would like to see these horses rehomed to better people, the best thing they can probably do is put them down... Because all those chemicals and all that weight on their feet, they're going to develop serious leg, foot, and back problems as they age... They'll all at least have arthritis, laminitis, and serious issues with the hind legs. Like I noticed one horse there, he tried to take all his bodyweight off his front legs, but his hind legs could barely hold him up... I know if i had the money I would do whatever I could to fix these guys and make them happier, but I don't, and not many people who actually care do...
This reminded me of a story I read.. It's illegal, but people used to, and likely still do, burn racehorse legs so they feel nothing below the knee. It's so they can race through pain and injury. There was one of those horses who had been rehomed, and he wasn't real good on his feet because of it. One day him and another horse were playing, and the other horse kicked him. It was just enough that he fell over. He couldn't get back up, so his owner helped him up. She got the vet out there, who said that his back had given out as a result of all the stress that had been put on it because of his legs. They decided to put him down right then. Just before he was put down, all the horses in the field pushed against him to hold him up, and they gently lowered him to the ground when it was done. They then followed in a procession to his burial site.
