There is a difference between “thrush treatment,” and “horse healing.” NO THRUSH treats in 3-5 days in which time you should no longer notice the black, wet mess. Do the “pick-test.” Insert your pick into the thrush area and see if it comes out dry and clean. If so, this is proof that the bacteria is no longer active. Meanwhile, for extreme, deep-sulcus cases, be sure to keep dusting whenever possible while the “healing” takes place. NO THRUSH promotes a positive healing environment – but know that your horse is susceptible to reoccurrence until the crevices and the area between the heel bulbs close and grow back with healthy tissue. Depending on the tissue damage created by months/years of thrush, this may take a few weeks. Go to the Video’s link for additional education.
