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. Pyoderma can mimic dermatophytosis, demodicosis, pemphigus foliaceus, epitheliotropic lymphoma, etc.
