Vet Q & AWhat shampoo can treat my dog's black skin from a yeast infection?
Snoopy's skin issues could be a result of allergies or even systemic diseases (such as Cushing's disease or hypothyroidism) that can compromise the immune system and weaken the skin barrier to infection. Some yeast infections can be managed with prescription-based shampoos containing climbazole, ketoconazole, or other antifungals. To my knowledge, there are no safe and effective over the counter anti-fungal shampoos for dogs. Your vet should be able to prescribe an appropriate shampoo for Snoopy. I realize that you are unable to medicate Snoopy, but realize that some skin yeast infections do not respond to topical medications or shampoos alone and require oral antifungal medications. Hopefully this won't be an issue for her. I hope that she's on the mend soon!
