Sos-Frog: the frog, with its rubbery structure, in addition to having a shock-absorbing action, has an important role in the mechanism of dilation and contraction of the hoof, which is essential to ensure good circulation to the horse's limbs. In case of frog rot, sprayed regularly on the affected area (two, three times a week) helps the regrowth of damaged tissue. Sos-Frog is also indicated in the presence of woodworm, abscesses and detachments.
