I think his hooves look good too. Actually it looks like he has nice frogs developing. Which has gotta mean he's getting lots of heel first landings.
His hooves look pretty healthy. I really can't find anything to point out or address.
I've been wondering what that streak of liquid is on the the front hooves. But with that liquid there it appears that he's got a few ripples right under the coronet band. There are certain things that if the horse eats em they'll cause the wall to let go at the coronet band which will cause ripples like that. Things like sweet feeds, lots of grains, eating tons of grass out in the pasture with little movement. Lots of horses will founder in the spring time because of all that new grass that is growing. I know someone who has to take special precautions with one of her horses in the spring because her mare will founder every spring if no one intervenes.
Another thing the ripples could be is from excess wall pressure in-between the trims. But I do also notice a couple ripples in the past growth. One was approaching ground level and the other was just above the midway point.
Another thing to consider is detox for the horse. I have yet to use any type of detox, but as soon as my debit card gets here I'm going to order the MOP described from this article. http://www.tribeequus.com/detox.html
Looking at those pictures at the bottom of the page has my wheels turning.
That new growth looks so amazing. And I educate myself on the human diet and how to cleanse the body so I really understand the importance of diet and cleansing. And this is one thing that I know is real important to bring superb health to our horses.
I think I read that you were going to finish up the trim sometime in the next few days or so. If you take more pictures can you get a few different angles. Here's a link and the pictures in the pre-trim area are really good examples. All of the angles while the hooves are being held are really nice to give an idea of the shape of the hoof and how everything is growing. http://www.healthyhoof.com/case_studies/BC/BC.html
A good resource I've used to help me learn is to go through those case studies and just look at the pictures first before reading the story. One thing that really popped out to me in that link is the coronet bands while the hoof is on the ground in the pre-trim.
