My 11 year old paint horse was diagnosed with osteo-arthritis in his proximal intertarsal joint of his left hock. Vet said that arthritis in that high movement joint was rare and that he probably did something to make it that bad since it is almost fused 😞. He also has moderate arthritis in the lower hock joints of the same hock and mild arthritis in the lower hock joints of the other hock. I had both hocks injected and he was feeling way better for 2/3 months. He is currently ridden (doing low level dressage) and walks fine but since it has gotten colder he limps for a good 5-10 minutes when we start trotting. He is on 1/4 pill of previcox a day. Which doesn’t seem to help anymore. He is also on Omega Alpha’s Sinew-X + HA but i’m looking for a better joint supplement. I know there are so many options so please share what worked for your horse and I’m wondering if anyone has a rare case like my horse that has arthritis in his high movement hock joint😞.
