My horse has transitioned to outdoor board over the last week. We are in the middle of winter and the ground freezes over night and thaws during the day. The reason for turnout was muscle atrophy after a long stall rest and potential ulcers. Since Sunday I think I have noticed some soft fluid around the point of his hock. He seems sore on it today. I think this is a result of sleeping on the frozen ground and pressure. Any helpful tips and tricks to cushioning this area?
*note he has an old sarcoid on this hock
