Very happy with EquineCare Probiotic spray. I use on greasy heel as a preventative maintenance. This year, 2022, with the extreme wet weather the greasy heel got away from me a bit, but no where near as bad as before ECB. I love the fact that you can spray it on, my mare was quite reactive when she had a bad dose a few years ago, spraying meant I could treat her twice daily without getting hurt.
