I was giving Blaze his boy manicure tonight (i.e. Putting hoof dressing on his hooves) and took some pictures of his front hooves. The frogs look very odd to me, and would love some more opinions. I've never smelled any odor that could indicate thrush. He is pasture boarded 24/7 so he probably does a lot of standing around in the mud munching hay with the other boys.
Left front hoof:
(btw I know he's due for a trim, the farrier comes out Saturday)
Nope, not that I can tell. I've watched him walk a few times this week, I've paid close attention to his gaits when I'm on his back and I've pressed all over the frog and it doesn't seem to bother him (nor while I'm picking).
My horse's frogs look different all the time, once a big flap(like almost 1/4 of an inch thick) of frog came off of both of Patches' (paint pony) front frogs. If he's acting normal I wouldn't worry about it. Good for you for being observant though :)
My hubby is all in a tizz at the moment because our warmbloods frogs are kinda peeling off. Its nothing to worry about though as far as I've been told. I've seen it dozens of times and theres no probs with it ;)
