My dog's crusty, itchy, yeasty skin returns despite medicated shampoo.

Question

My dog has a crusty raised spot and dark spots around it. I use medicated shampoo (DOUXO) Chlorhexidine monthly on her but it returns. Seems to itch her mildly. I think she smells a little yeasty also. She has had quite a history but is hanging in. She turned 15 recently. Pet's info: Dog | Cockapoo | Female | spayed | 15 years and 1 month old | 25 lbs

I would probably have Sissy checked out by your vet. A chlorhexidine shampoo will help with superficial bacterial skin infections, but this may not be the cause of the crusting. It could also be caused by a fungal infection, deep bacterial infection, endocrine disease such as Cushing’s or hypothyroidism, mites, allergies, etc. The yeasty smell is often associated with allergic skin disease. Your vet can help you decide on a treatment for this, which may include oral medications, a different shampoo, or a special diet.
