My little terrier was tortured with yeast infections for quite some time. Black skin, hair loss, broken skin, incessant itching and chewing. Between the vet and every remedy I could find, some worked a bit but no cure until I found a comment on line. The vaginal cream women use for yeast infections! Yes, it works! I bathe him 2-3 times a week, dry him completely, then smear it on, focusing on the armpits, rump, feet and wherever I see black. Voila!
