I noticed a major injury on my horse’s face today. It looks like there was some trauma above the eye. When going back through photos and history, it has become clear that It happened while he was at my trainers at least 2 weeks ago. I noticed it when I had him home for a few days for a break this week. I see him twice a week while he is in training and did not notice it until he was home. My trainer also did not notice it while he was in her care. He seems to be acting normal but I am concerned that a major injury happened and it was not noticed. I have an appointment for the vet asap.
How would you deal with this situation if you noticed a potential serious injury that was missed while your horse was in your trainer’s care?
