200. Derm wrap up for 2023!

Send me a question or story!For how common we see pyoderma in cats and dogs in veterinary practice, the appearance can be variable. A cutaneous bacterial infection can appear as crusting, erythema, scaling, moth-eaten alopecia, epidermal collarette, etc. Differentials can also be varied.
