I have been round the field with a fine tooth comb and there's nothing that is untoward there at all.
Opinions on the yard are that it's a kick, but the vet says the marks are inconsistent with a kick and it's a nail in the fence. It is definitely not a nail, as there are none in the fence. The yard opinions are based on the fact he's very young and getting himself into bother with the other horses. He's also the new boy on the yard.
There are two tiny marks if you can see them, one above the knee and one above the fetlock.
What do you guys think please?
