Yesterday when I went to take my horse out I noticed that his right back leg was swollen but there was not tenderness or heat coming from it so I assumed it was him just stocking up from being in the stall and so I took him out and round penned for a few minuets and after his leg was no longer swollen. I recorded me round penning so I could review further and ask other people's opinions. I think he might be stiff in the right hip maybe? I'm not sure because it's not that noticeable, but I could just be thinking I see something that's not really there. Does anyone see what I see or am I loosing my mind?
