I have two horses a quarter horse (Blaze) and a giant Belgian (Dave). I call Dave a giant Belgian because he is bigger than the average Belgian. He is about 3 inches taller than me at his should, I am about 6 foot with my boots on so that makes him about 6'3 foot at the shoulder. Anyways, I need to get some dewormer for Dave and Blaze because it has been a while since they have got any. I also want to get some joint supplements for Dave because he doesn't seem to want to move his joints much. I am pretty sure Dave has joint problems because of his size he weighs well over 2,000 pounds. So any help on what joint supplements would be the best for Dave and what dewormers would be the best for Blaze and Dave, would really be appreciated.
