So my mare has tender soles and I am trying to keep her barefoot and using a natural barefoot trimmer right now. I was told Durasole is a great product and I ordered some and just used it for the first time. I did what was suggested on their site which was to clean hoof then dry with blowdryer then apply with a toothbrush. I covered entire sole and frog. However in reading some info online from different sources I saw someone who said not to put on frog and that he had horses that it had caused problems with? UGH just what I need are more hoof problems :( Just wondering what everyone here's experiences with this product might of been and any suggestions you have? The product manufacturer does state it is for the equine sole "and frog". Thanks!
