Thirty-four dogs with superficial pemphigus (pemphigus foliaceus, pemphigus erythematosus) were treated with tetracycline and niacinamide (TCN). Follow-up information was available for 29 dogs and 62% of those responded satisfactorily to TCN. Success or failure of TCN treatment was not associated with patient sex, duration of disease prior to treatment, previous systemic glucocorticoid therapy, the presence or absence of pruritus, duration of TCN administration, TCN dosage, ability to reduce the frequency of administration of TCN, or distribution of skin lesions.

A 6-year-old, spayed female Shiba inu presented with pruritic behavior on the right ear. The dog had been diagnosed with otitis externa and treated in other clinics. Auripuncture and flushing of the tympanic bulla were performed under video otoscopic examination to collect the content. Based on the presence of bacteria in the content, the dog was diagnosed as having otitis media. The dog was administered antibiotics to which the bacteria were susceptible for 2 months. Pruritic behavior improved, and auripuncture under video otoscopic examination revealed no bacteria in the tympanic bulla. Auripuncture and flushing of the tympanic bulla under video otoscopic examination were found to be effective in the diagnosis of otitis media in the present dog.
