I have a 14yo Standardbred. He had a long, successive racing career but as far as i know he's always been well looked after. He's very happy with humans so i can only assume this. I ride him 2-3 times a week (full time work sucks) and when we go for a ride, we do have fun. walk trot canter and sometimes gallop. I'm not stupid, i know horses will run themselves into the ground so i never push him too much. We lost one of our 18yo TB's to a heart attack the other week, he had just been cantering through heavy sand. This made he wonder if i should slow my horse down a bit. I trust my judgement and i know 14 isnt very old but i'd hate to think im pushing him too far, what do you think?
