Sorry but pics are necessary for an answer
1. No pics of wet hooves. Pick them clean, then brush top and bottom with a stiff bristled brush.
2. Clear daylight view of the undersides.
3. Stand the horse on something level like the barn floor, cement, gravel driveway will work as long as the gravel isn't new and sticking up all over the place
4. Stand the horse square on the fronts when taking those pics and square on the backs when taking those pics.
5. Set the camera at ground level, aimed for a side view of each hoof and then set the camera at ground level aimed for a back view of each set of hooves.
Hopefully you can do that in the daylight or in excellent barn light.
It's too bad I can't practice what I'm preaching as I am probably the worst one on this forum for trying the hardest to get the best pics and they turn out the worst
Anyway, there are some great trimmers and farriers on this forum that will be happy to look at your pics and help you along - I am not one of them
