It's actually very possible to look over something like that. A woman wanted me to start one of her younger horses under saddle because she had gotten on him a few times and wasn't very confident with him. Anyway, I ended up at her house and got the little guy out and started getting to know him and grooming him and noticed he was very slightly limping. When I asked about his limping she said he had always done that. Well, I picked up the hoof he was favoring and looked and couldn't find anything...walked him around again watching how he walked and still didn't like it. When I picked up his foot again I poured water over his frog and felt all over it with my fingers. I found a shard of glass about the size of a dime stuck right in the pointy part of his hoof that had almost grown embeded in his hoof. We had to cut it out and the woman felt awful because she had been over looking it too.. Don't be hard on yourself. Just let him take it easy and see how it goes.
