one of the Bloodhounds on our SAR team kept getting reacurrent fungus on his skin, he was a beautiful BH, not at all what you see in the show ring, those to me are way oversized.
anyway, he was the true working dog with a nose to die for.
the gal did some research and finally came up with a natural remedy.
they told her to feed him Cinnamon in his food.
i believe it was either a pinch or a teaspoon twice a day.
it worked.
it took some time, but, it did do the trick.
you guys might want to do some research on cinnamon and see if it is a worthy thing to try.
