Well the vet believes that it's just a muscle over exertion issue. Not exactly back sore from an injury or trauma, more like a little too much for too long. She's going to cut down on asking him to lift his back - I suggested using a timer and coming up with some method. The vet is a rider which I really like and recommended more stretching at the warmup. Specifically doing more slow, long and low (there's another term for it but it escapes me - forward and down?) and asking him to do poles and cavalettis while long and low in the warmup. She also recommended a mini break during work to do the same and to do the same during cool down. This is to encourage the muscle to stretch more and help build it up more gently. The vet does not believe it is serious based on the information we gave her and what she saw.
All made sense to me and seemed very reasonable!
On a side note, she said my horse had a beautiful topline! She also said my horse was sassy, LOL. I think I will also be doing the same exercises with my horse - can't hurt. Posted via Mobile Device
