Anyways, he did two weeks of nothing! I would bring him out of stall rest to brush him, pick feet, and give him some fresh air outside just walking on a daily basis. The last couple of days he was feeling better, I put him in the round pen then arena to kick up his heels a little. Free lunged in round pen night before last (we took it easy). Last night my instructor said she felt as though he was ready to start getting back into work (no more mucus and cough had disappeared). We were in the round pen working at walk and trot and I think he had forgotten everything he learned. Five months of work was forgotten. NO WHOA (was his fave word)! And rushing the walk, rushing the trot (what happened to my uber-lazy horse!!!). We spent our short time working on "easy" to slow it down and whoa without pushing our nose as far as we can! Granted he is young at just five, but I had no idea he would regress so much!
So, tell us how long your horse can go without work before you have to reintroduce yourself to each other!
