My 13 year old labradoodle has a yeast infection diagnosed

Customer Question

My 13 year old labradoodle has a yeast infection diagnosed by our vet. He was put on antibiotics but it seemed to make it worse. I have his ears under control but he smells terrible and scratches everywhere, scoots on his behind and licks his paws. I have been treating with vinegar water and it has helped some. Can I use mono stat on his coat and paws?
JA: I'm sorry to hear that. Using the wrong medication for fleas can be dangerous. You should definitely talk to the Veterinarian. What is the dog's name?
Customer: His name is ***** ***** he has been to the vet. He doesn't have fleas.
JA: Is there anything else important you think the Veterinarian should know about Doodles?
Customer: He has been going to this vet for over year now so he knows Doodles quite well. Doodles had pancreatitis last Christmas.

I'm sorry to hear of this with Doodles. Can you tell me which antibiotic was prescribed? Ketoconazole dosed at 5 mg/lb once daily for a month plus shampooing twice weekly in a chlorhexidine- and ketoconazole- or miconazole-containing shampoo usually is quite effective when addressing widespread yeast. Here's my more complete synopsis of yeast infection for you:

1. Any underlying cause (allergies/food intolerance, atopy, e.g., endocrinopathy/hypothyroidism, e.g., keratinization defect/seborrhea) must be identified and corrected.

2. For mild cases, topical therapy alone is often effective. The patient should be bathed every 2-3 days with shampoo that contains 2% ketoconazole, 1% ketoconazole/2% chlorhexidine (https://www.amazon.com/Keto-C-Ketoconazole-1-Chlorhexidine-Shampoo/dp/B00Q34IY6Y), 2% miconazole, 2-4% chlorhexidine, or 1% selenium sulfide (Selsun Blue). Shampoos that have two active ingredients provide better efficacy. Treatment should be continued until the lesions resolve and follow-up skin cytology reveals no organisms (approximately 4 weeks).

3. The treatment of choice for moderate to severe cases is ketoconazole or fluconazole 10 mg/kg orally with food every 24 hours. Treatment should be continued until lesions resolve and follow-up skin cytology reveals no organisms (approximately 4 weeks).

4. Alternatively, treatment with terbinafine 5-40 mg/kg orally every 24 hours or itraconazole (Sporanox) 5-10 mg/kg every 24 hours for 4 weeks may be effective.

The prognosis is good if the underlying cause can be identifed and corrected. Otherwise, regular once- or twice-weekly antiyeast shampoo baths may be needed to prevent relapse. Please respond with further questions or concerns if you wish.
