so he hasn't been out running for almost a week. I have no idea what was wrong. He just wouldn't put it to the floor. He has done this twice in the past but both time it was a little swollen and slightly hot. I felt everywhere! up and down his leg, in betweeen his toes, his nails his pads (looking for grass seeds). Anyway I found some Mexacam in the animal medicine cupboard - he's had three doses and now he seems fine so off we go for his run in about 20 mins.
