That's awesome and congratulations. I've seen some serious changes in all hooves with the wonky weather this past several years (maybe 5 yrs in total, just seems like the abnormal is becoming normal). The ones' we've had continuously since 2009 have been most noticeable.
Having an issue now with the "newest" mare (who is currently the 2nd oldest on our property). She is actually shedding her soles and w/ the sand packing into her hooves (normally considered a good thing w/ everyone else, but it literally mounds up like a tennis ball is strapped to the bottom of her hoof) she keeps going lame. Even our farrier is at a loss as to why it won't knock out on it's own - seems worse in the left fore than the right. When this sore, she doesn't move around as much as she should, which doesn't help. She has not had a bounding pulse or heat in hooves or in pasterns. We are also thinking she may be starting (or continuing?) changes that may be due to Cushings or other age related metabolic changes. We shall see. Will be having her tested, may be sooner rather than later.
Have seen a lot of changes on this new property & now, 2 months after all the wet, rainy weather with Hurricane Matthew we are seeing some more. Will be trimming the hooves on the boys in 2 weeks - they had a wetter pasture than some of the others as water flowed thru it...
