Thank you. Can you upload photos of representative skin in those areas to our conversation? You can upload photos by texting them, or by using the paperclip or add file icons above your message box...if you can see those icons on your device. You can also use an external app such as dropbox or navigate to and scroll down to "other".

Ah! The areas you've mentioned are often heavily colonized by yeast. The underlying reason for this is usually allergic dermatitis - atopy or food intolerance and so I'll post my synopsis of both for you.

Environmental allergies (atopy) are usually initially addressed with a steroid such as prednisone. In some dogs an over the counter antihistamine such as chlorpheniramine (many generics) at a dose of 0.1 - 0.25 mg/lb (maximum) every 8-12 hours or diphenhydramine (Benadryl) dosed at 1-2 mg/lb every 8-12 hours (maximum dose of 50 mg at any one time) may be effective. Antihistamines, however, aren’t reliably effective. Adding fish oil to the diet at a dose of 20 mg/lb daily of the EPA in the fish oil might synergize with antihistamines to provide better anti-pruritic action. The omega-3 fatty acids in fish oil are anti-inflammatory but may take 8-12 weeks to kick in. The cytokine antagonist oclacitinib (Apoquel) is likely to revolutionize how we address atopic dogs and should be discussed with Rosie's vet. Oclacitinib works as well as a steroid but without a steroid's adverse effects. The injectable Cytopoint is another good immune mediator to consider. Bathing twice weekly in a noninsecticidal shampoo can rid her skin of offending allergens and thus hasten remission of Rosie's atopy.

Food intolerance/allergy is addressed with prescription hypoallergenic diets. These special foods contain just one novel (rabbit, duck, e.g.) animal protein or proteins that have been chemically altered (hydrolyzed) to the point that **immune system doesn't "see" anything to be allergic to. Over the counter hypoallergenic foods too often contain proteins not listed on the label - soy is a common one - and these proteins would confound our evaluation of the efficacy of the hypoallergenic diet. The prescription foods are available from Rosie's vet. There are many novel protein foods and a prototypical hydrolyzed protein food is Hill’s Prescription Diet z/d (I prefer the hydrolyzed protein diets because they lessen the possibility of my patient being intolerant to even a novel protein.) A positive response is usually seen within a few weeks if we’ve eliminated the offending food allergen. Food intolerance can arise at any age and even after our patient had been eating the same food for quite some time.

It's important that Rosie's vet performs cytology (microscopic exam of a small sample of affected skin surface looking for abnormal numbers of both bacteria and yeast). These infectious agents will need to be eliminated before treatment for allergic dermatitis can be completely effective.

Please continue in this conversation if you wish.
