There's a few things DS that have contributed, his weight is a huge factor though so yes you're right. His conformation and the type of trim he was getting are other possible contendors. I'm also trying to do as much as I can to lose weight so he's not carrying such a heavy load. I do think he's feeling better in himself lately, although yesterday when I rode, he was a slug and a bit lame. We shall see if it is just bridle lame. He's on turmeric now for the past week and I'm hopeful. Lets hope there is another vid in six months with a vast improvement! The last thing I need to get checked now is his back. Saddle, teeth, feet have been checked. Friend is getting back man out soon so will get him a nice massage so we can check if he's compensating badly in any way.
