If you read second post by OP it states this is only the third time this farrier has shod horse. So who knows how feet will look months down the road.
There are issues patty stiller pointed out loosie has also pointed out some things. Its not a horrible job but certainly not the best eihter.
Took more then 3 visits from farriers I fired to figure out they werent going to fix anything. All of fired farriers wouldnt listen to any concerns either. So when my concerns fell on deaf ears... they werent coming back and they were let known.
We don't know what the feet looked like prior to this shoeing, and the 2 before that. It looks to me like he's trimmed the toe back as far as he could, and moved breakover back a bit which shows me that he knows what he's doing. It appears that bringing the heel back any further would have sacrificed the angle, which he was smart enough not to do. It does not look like the horse's hooves are getting worse, they look well maintained.
It took a farrier over 8 months to get my horse's angles on the positive side while bringing the heels back. It took time. My farrier prior to that tried to do it in 2 trims and failed. All he got was a negative palmer, and was not invited back.
OP also said that the farrier is easy to communicate with, and that's worth a lot too. He does listen to her.
On any hoof, there is always room for improvement, I haven't seen any perfect hooves yet except in a book.
What's nice about this forum is that there is so much food for thought offered from different opinions . Patty and Loosie are 2 of a bunch here who are so knowledgeable I love reading their replies, and learning lots ,whether I agree or not.
I think the OP can ask the farrier next time what he sees as his goals with her horse's hooves, and what the plan of care is. That would be the most polite way of finding out if it's what you believe the goals should be.
