Holes in frogs/ heels

[moosea]

Hi
I share a 16.1 hh ID x 17 years old.

We have only had her 4 weeks and had her shod about a week ago.

Small holes have appeared in the frog towards the bulbs of heels.
They are not sore or smelly. No sign of thrush and no lameness or sensitivity there.

Her feet were not in the best condition when we got her but the farrier we have now is working on this!

What could they be and do we need to treat them or is it old frog growing out?

Thanks

How deep are these holes?? if they are only a few mm deep, then i think they are normal holes, i wouldnt worry about them, if they are deep holes then i dont have a clue

There are tiny scent glands in the back of the frog - this is how a horse can retrace his steps. Apparently they are good for about 20 miles which is why horses that wander further than this can get lost.

No, I am not making this up , Bob Bowker told me about them.

I never knew that brucea! We can't see them normally though? I've never noticed any holes.
