A 12 year old thoroughbred horse is brought to your clinic. The owner complains the horse was slightly lame in the front left foot a few weeks ago, but now he's showing lameness in the right hind limb. He is generally kept in a box stall in a barn during the day to avoid the flies but let out to a small grass pasture all night. You observe the horse and note bulging over the maxilla on both sides of the head. You also note that the pasture has little grass in it - and the warm season grass is overgrazed.
