First, this big crack has appeared in the past two days. But, what's bothering me more is the underside of that same foot. It's very soft, with a bad smell. When you use the hoof pick, the sole has a lot of "give" under the pick. When you rub it with your finger, it "smooshes" a little. There is black gunk on the side of the frog that makes me wonder about thrush. I also don't love the look of the frog itself.
I don't know how we could have thrush right now, it's so hot and dry, the ground is hard, her stall is well cleaned every day and her feet are picked every day. There are a lot of flies and the horses are stomping on the hard ground to get rid of them, so I'm not as surprised about the chips and cracks around the edges. It's been about 5 weeks since her last trim, she gets done every 6. She's always been barefoot.
The left front has some chips and cracks around the edges but not the same soft sole. The backs look good. She isn't sensitive or so in any way she's letting on. Rode her today and she felt great.
So, two questions:
1. The crack on the front- what should I do to help it and what should I be worried about with that?
2. The soft, crumbly sole- this is scaring me a bit. Any thoughts on what it is? What can I do to help it?
